Free and Premium AAPC CPC Dumps Questions Answers

1. Procedure and CPT® Code Selection:

The procedure performed was a hysteroscopy to examine the uterine cavity due to abnormal vaginal bleeding. This is a diagnostic hysteroscopy.

CPT® Code 58555 is specifically for a diagnostic hysteroscopy to examine the uterine cavity, which aligns with the procedure performed in this case.

2. Rationale for Excluding Other Options:

Code 58558 is for a hysteroscopy with a surgical procedure, such as biopsy or removal of a lesion or polyp, which was not performed in this case.

Code 58579 is an unlisted procedure code for the female genital system and is unnecessary here because there is a specific code (58555) for diagnostic hysteroscopy.

Code 58578 is also an unlisted hysteroscopic procedure code and is not appropriate when a specific diagnostic code exists.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines indicate that 58555 should be used for diagnostic hysteroscopy procedures without any surgical intervention.

Therefore, the correct answer, following CPT® guidelines, is C. 58555.

69209 = Cerumen removal using irrigation

69210 = Cerumen removal using instrumentation

Different techniques on different ears require separate codes with laterality modifiers

Procedure: Albumin Cobalt Binding (ACB) test to determine ischemic nature of chest pain.

CPT® Code:

83857: This code is used for the Albumin Cobalt Binding test.

Code Selection Justification: The ACB test specifically measures ischemia-modified albumin, making 83857 the appropriate code for this laboratory test.

1. Procedure and CPT® Code Selection:

The obstetric panel ordered includes the following tests: syphilis screening (non-treponemal), automated CBC with manual differential WBC count, HBsAg, rubella antibody, serum antibody screen, and ABO/Rh blood typing.

CPT® Code 80055 is for a comprehensive obstetric panel that includes all these components. This code is intended to report the entire panel of tests as a bundled service rather than itemizing each individual test.

2. Rationale for Excluding Other Options:

Option B lists the individual component codes for each test in the obstetric panel (e.g., 85027, 85007, 87340, etc.), but using 80055 is more appropriate because it provides a single code to report the full obstetric panel and follows CPT® bundling guidelines.

Option C also lists the individual tests separately, which is unnecessary when 80055 includes all these components.

Option D lists 80081, which is for an obstetric panel that includes HIV testing. Since HIV testing is not part of the tests described in this scenario, 80081 is incorrect.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines recommend using the single code 80055 when all components of an obstetric panel are ordered together, as itemizing each test individually is not necessary.

Therefore, the correct answer is A. 80055.

1. Procedure and CPT® Code Selection:

The patient underwent a thyroidectomy for malignancy in the right lobe, as well as the removal of the parathyroid gland due to a suspected malignant lesion.

CPT® Code 60505 is for the parathyroidectomy with exploration of parathyroid glands and is appropriate for the removal of the parathyroid gland due to a suspected malignancy.

CPT® Code 60220 represents a thyroid lobectomy (total removal of one lobe of the thyroid), which applies to the removal of the right thyroid lobe in this case.

2. Modifier 59:

Modifier 59 is added to 60220 to indicate that the thyroid lobectomy is a distinct procedure from the parathyroidectomy, performed in a separate anatomical site during the same surgical session.

3. Rationale for Excluding Other Options:

Code 60500 (in options A and C) is for a parathyroid exploration only, not including the actual removal of the parathyroid gland, so it does not apply here.

Code 60240 (in option D) is for a total thyroidectomy, which involves removal of the entire thyroid gland. Since only the right lobe was removed, 60220 (thyroid lobectomy) is correct.

4. AAPC and CPT® Coding Guidelines:

Per AAPC guidelines, 60505 is the appropriate code for parathyroidectomy procedures involving exploration or suspected malignancy, and 60220 with Modifier 59 accurately reflects the separate and distinct thyroid lobectomy procedure.

Thus, the correct answer is B. 60505, 60220-59.

This is anestablished patient office visitcoded byMDM(or time, but time is not provided). Problems:one acute, uncomplicated illness(URI) → supportslowproblem complexity. Data: no labs/imaging ordered or reviewed →minimal/nonedata. Risk: although a prescription is given, MDM level is determined by2 of 3elements (Problems, Data, Risk). Here, only the risk might approach moderate due to prescription management, butproblems and data remain low/minimal, so the overall MDM doesnotmeet moderate. Therefore, the visit is best supported atlow MDM, which corresponds to99213for an established patient. It is more than minimal (99212) because a focused exam and management plan are documented, but it does not meet the higher complexity required for 99214/99215 (multiple problems, significant data review, or high-risk management). CPC exam focus: don’t let a single element (like antibiotics) automatically “force” a higher code—MDM requires meeting the level intwo elements.

This question tests matching each study to the correct radiology code family and recognizing CTA coding. Fornasal bones, CPT70160is the “complete” nasal bone study (minimum 3 views). Because only2 viewsare done, the best match in the provided choices is70160-52(reduced services). For theforearm (2 views),73090is appropriate; fortibia/fibula (2 views),73590is appropriate. ForCTA head with contrast, the correct CTA code in the options is70496(CTA head). Option C is the only choice that correctly includes70496and the correct extremity X-ray codes73090and73590and also handles nasal bones as reduced service. The chest portion is imperfectly represented across the options (3-view chest typically aligns with a higher-view chest code than 71047), but the CPC-style best answerwithin the provided optionsisCbecause it captures the key intended learning targets: nasal bones reduced, correct extremity radiographs, and correct CTA head code.

This scenario describes acytogenetic-type analysis targetingchromosomal abnormalities, performed using fluorescence-based microscopy techniques (commonly conceptually aligned with FISH-type evaluation). The question explicitly states thatno specific CPT code accurately describes the service, which signals that anunlistedcode is required. In CPT, the88299code is the unlisted procedure code forcytogenetic studies, used when a chromosomal/genetic laboratory procedure does not have a more specific existing CPT descriptor. The other unlisted options correspond to different laboratory sections:84999is an unlisted chemistry procedure,88199is an unlisted cytopathology procedure, and88749is not the correct unlisted cytogenetics code for this context as presented. CPC exam technique: match thedomainfirst (chromosomes → cytogenetics), then select the appropriateunlisted code within that domainwhen the stem says no specific CPT code exists. Proper use of unlisted codes also implies documentation of method, purpose, and comparables for payer review, but the test asks only for the correct unlisted CPT code.

In ICD-10-CM coding, an Excludes2 note under a code indicates that the condition listed in the note is not included in the definition of the code, but it does not necessarily mean they cannot coexist. This type of note means that while the conditions are distinct, it may be appropriate to report both codes if a patient has both conditions at the same time.

A. is incorrect because Excludes1, not Excludes2, indicates that certain codes should not be reported together.

C. is a description of an Excludes1 note, which implies that the two conditions should not be coded together because they cannot occur simultaneously.

D. is also a description of an Excludes1 note, which serves as a "NOT CODED HERE!" directive.

Therefore, the correct answer is B. It is acceptable to report both the code and the excluded code together, when applicable.

Cervical spondylosis with myelopathy: Condition requiring decompressive surgery.

Bilateral posterior laminectomy, facetectomies, foraminotomies: Procedures performed to decompress nerve roots.

Interspaces C5-C6 and C6-C7: Specific levels where the procedures were performed.

CPT code 63045 is used for the initial cervical laminectomy, and 63048 is for each additional segment. The combination covers the decompression across two interspaces.

In CPT, a code labeled“separate procedure”is typically a service that isnormally includedas part of a more comprehensive procedure andshould not be reported separatelywhen performed as an integral component. However, itmaybe reported when performedindependentlyorunrelatedto the primary procedure—this supports options A, B, and C as true. The false statement isDbecause CPT doesnotinstruct that modifier79is specifically required to report a separate procedure with an unrelated primary service. Modifier selection depends on the actual circumstances and payer rules, and “separate procedure” logic is about whether the service isdistinct and not integral, often supported by documentation of a different site/session or separate clinical intent; when a modifier is needed, it is commonly adistinct procedural servicemodifier (e.g., 59 or X{EPSU}) rather than automatically 79. Modifier79is a global surgery modifier used for anunrelated procedure during the postoperative period, which is a different concept than “separate procedure” designation.

1. Procedure and CPT® Code Selection:

The patient underwent an appendectomy performed via laparoscopic approach. The procedure involved removal of the appendix using a scope inserted through an umbilical incision.

CPT® Code 44970 is specific for a laparoscopic appendectomy, which is the correct code for this procedure.

Code 44950 would be used for an open appendectomy, but since this case was performed laparoscopically, 44970 is appropriate.

2. Diagnosis and ICD-10-CM Code Selection:

The diagnosis given by the physician is chronic appendicitis.

ICD-10-CM Code K36 is used to report chronic appendicitis, which is the definitive diagnosis in this case.

Additional codes for symptoms such as nausea (R11.2) and right lower quadrant pain (R10.31) are not necessary because the primary diagnosis of chronic appendicitis (K36) fully explains the symptoms, according to ICD-10-CM guidelines on coding symptoms when a definitive diagnosis is available.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines indicate that when a definitive diagnosis is established, symptom codes should not be reported separately. The use of 44970 for laparoscopic appendectomy and K36 for chronic appendicitis is fully supported by these coding standards.

Therefore, the correct answer is C. 44970, K36.

Shave removal → CPT 11300–11313, not excision (11400–11646).

Face (nose) → 11310–11313

0.6–1.0 cm → 11311

Inflamed seborrheic keratosis → L82.0

Codes69209(removal of impacted cerumen by irrigation/lavage) and69210(removal of impacted cerumen requiring instrumentation) are intended forimpacted cerumen, so documentation must support that the wax isimpacted—not merely present. That makes optionBthe most accurate statement. OptionAis incorrect because you generally donotreport both methods for thesame earin the same session; you select the code that reflects the method required for that ear. OptionCis not reliably correct for CPT rules because bilateral reporting for cerumen removal is typically handled using the payer’s bilateral instructions (often modifier50or separate line items depending on payer), not a universal “report twice” instruction. OptionDcan be true in certain circumstances (significant, separately identifiable E/M), but it is not the core parenthetical principle tested here. CPC exam focus: impacted requirement + select the correct method code.

When a therapeutic colonoscopy is attempted but does not reach the cecum, it is considered an incomplete procedure. According to the CPT® Colonoscopy Decision Tree, if the colonoscopy extends beyond the splenic flexure but does not reach the cecum, the appropriate way to code this incomplete colonoscopy is by appending modifier 53 to indicate a discontinued procedure due to extenuating circumstances or risk to the patient.

A. 45378-53 is the correct answer as it designates a diagnostic colonoscopy with modifier 53, signifying that the procedure was started but not completed.

B. 45330 is incorrect as it represents a sigmoidoscopy, which only goes up to the splenic flexure.

C. 45331-45347 refers to therapeutic colonoscopies that were completed to the cecum.

D. 45379-45398 with modifier 52 is incorrect because modifier 52 is used for reduced services, which does not accurately describe an incomplete colonoscopy.

Thus, the correct answer is A. 45378-53.

The scenario describes an emergency basic life support (BLS) ambulance service. The appropriate HCPCS Level II code for BLS emergency transport is A0429.

Modifier QN indicates that the service was provided by an ambulance supplier, and SH indicates the services were provided in an emergency situation.

Dacryocystitis is the inflammation of the lacrimal sac, which is part of the tear drainage system located in the inner corner of the eye. The lacrimal sac is connected to the nasolacrimal duct, which drains tears into the nasal cavity. Inflammation in this area can cause pain, redness, and swelling near the inner corner of the eye.

ICD-10-CM, medical dictionaries

The adenoids, tonsils, appendix, and spleen are all part of the lymphatic system, which plays a crucial role in immune function and the filtration of pathogens. These organs contribute to the body's defense by trapping and eliminating bacteria and other pathogens.

Adenoids and tonsils are lymphatic tissues located in the throat and help prevent infection by filtering pathogens from inhaled or ingested particles.

The appendix contains lymphoid tissue and is thought to play a role in gut immunity.

The spleen filters blood, removing old or damaged blood cells and producing lymphocytes for immune response.

The other options are unrelated:

B. Gastrointestinal: Involved in digestion, but not specifically immune response.

C. Cardiovascular: Involved in blood circulation, not immune response.

D. Nervous: Coordinates sensory and motor functions, unrelated to lymphatic tissue.

Therefore, the correct answer is A. Lymphatic.

Facet joint injections (medial branch blocks/intra-articular depending on code family) are coded byspinal regionandnumber of levels. Thoracic facet injections use64490for thefirst level,64491for thesecond level, and64492for thethird and each additional level(within the thoracic region). This case includesthree thoracic levels: T2–T3 (1st), T3–T4 (2nd), and T4–T5 (3rd). Because the injections arebilateral, you applymodifier -50to each of the level codes per the answer set’s style. Fluoroscopic guidance isbuilt intothese injection codes under current CPT rules, so you donotseparately report a fluoroscopy code (such as 76000). Options B and C are forlumbar/sacralfacet injection families, not thoracic. Option A incorrectly doubles units rather than using the correct third-level add-on coding structure. Therefore,64490-50, 64491-50, 64492-50is correct.

1. Procedure and CPT® Code Selection:

The patient underwent a bilateral excisional vasectomy for sterilization.

CPT® Code 55250 represents a bilateral vasectomy with excision, which includes postoperative care. The code already implies a bilateral procedure, so it is not necessary to add the -50 modifier for bilateral designation.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code Z30.2 is used for encounter for sterilization and is the correct code to report for a planned sterilization procedure such as a vasectomy.

Code Z30.012 is specific to encounter for sterilization of a female patient, which does not apply in this male patient scenario.

3. Rationale for Excluding Other Options:

55250-50 (in options C and D) is unnecessary because the CPT® code 55250 inherently covers a bilateral vasectomy, and applying the -50 modifier is redundant.

Z30.012 (options B and D) is incorrect as it pertains to female sterilization procedures, not male.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 55250 is reported without a bilateral modifier, as the procedure inherently covers both sides. Additionally, Z30.2 is the correct ICD-10-CM code for male sterilization procedures.

Thus, the correct answer based on CPT® and ICD-10-CM guidelines is A. 55250, Z30.2.

Malignant lesion destruction → CPT 17260–17286

Trunk/extremities

0.6–1.0 cm → 17261

1.1–2.0 cm → 17262

Both lesions are reported separately.

This question tests two things: theextentof vulvectomy and the correct diagnosis code forVIN II. VIN II corresponds tomoderate vulvar dysplasia, which is coded asN90.1. VIN III would map to more severe dysplasia/carcinoma in situ-type coding; that is not what is documented here. For the procedure, the surgeon removed aportionof the vulva (less than 80%), including skin and deep subcutaneous tissue, which describes apartial (simple) vulvectomyrather than a radical vulvectomy. CPT56625represents asimple partial vulvectomy(partial removal). CPT56630is forradical vulvectomy, which is more extensive and not supported by the “less than 80%” partial description. Option D pairs an incorrect diagnosis code, and option C uses a diagnosis code that doesn’t match VIN II. Therefore, the correct combination is56625 with N90.1.

99222: This code is used for initial hospital care, per day, for the evaluation and management of a patient, which requires a detailed or comprehensive history, a detailed or comprehensive examination, and medical decision making of moderate complexity.

The documentation shows a detailed history (including HPI, ROS, PMH, SH, and FH) and a detailed examination (covering multiple organ systems). The medical decision making involves the management of an acute asthma exacerbation, which includes admitting the patient to observation status, administering oral steroids, and planning for further diagnostic testing.

Correct answer: A

1. Procedure and CPT® Code Selection:

The scenario describes the repair of a bleeding vessel in the patient’s right hand. The procedure involved clamping, cleaning, preparing the wound, suturing the vessel, and confirming blood flow post-repair using a Doppler probe.

Code 35207 is the correct CPT® code for a repair of a blood vessel in the hand or finger. This code specifically covers the repair of an injured vessel in the extremities, which includes the hand.

Code 35206 is for vessel repair in the upper arm or elbow, which does not apply to this case, as the injury is located in the hand.

Code 35702 is for exploration of a vessel but does not cover vessel repair, making it unsuitable for this procedure.

Code 35236 pertains to the repair of vessels in the lower extremities and is not relevant here.

2. Modifier:

Modifier RT is used to indicate that the procedure was performed on the right side of the body.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines specify the use of codes in the 35201–35286 series for direct repair of blood vessels in specific anatomical areas. For hand vessel repair, 35207 is the precise and recommended code according to CPT® guidelines.

Thus, based on the CPT® guidelines and procedural details, the verified answer is A. 35207-RT.

55250 = Vasectomy, bilateral procedure inherent (no modifier -50)

Z30.2 = Encounter for sterilization

Z30.012 is for contraceptive management counseling, not the procedure

Preventive medicine codes are selected bypatient ageand whether the patient isnew or establishedto the provider. The child is3 years old, which falls into theearly childhoodpreventive age range. Because the child has been seen by this same primary care physician before (last exam two years ago), the patient isestablished, not new. For established patients, preventive codes are99391–99395, and for age1–4 yearsthe correct code is99392. However, among the answer choices, the closest matching established preventive code offered for this age group is99382, which is actually thenew patientpreventive code for age 1–4; the item’s provided options appear to omit 99392. Given CPC exam rules, the correct code should be99392for an established 3-year-old. But since it is not offered and you must pick among A–D, the best keyed answer in this option set isD (99382)as presented. Exam tip: Always verifynew vs establishedfirst, then pick the age band.

72114 = Radiologic exam, lumbosacral spine, complete with bending views

Other codes represent fewer views or different spine regions

Newborn circumcision coding depends primarily on whether the circumcision is performed using aclamp/device techniqueversus asurgical excision technique. CPT54150is commonly associated with circumcision using a clamp or other device method (often described with a Gomco/Mogen-type approach in many training contexts). In contrast, CPT54160representssurgical circumcisionusing acircumferential incisionwith excision of the foreskin—matching the documentation (“circumferential incision… foreskin excised with a scalpel”). The infant’s age (8 days old) supports that this is a newborn service, but the decisive factor in this vignette is thetechnique described. Modifier-52(reduced services) is not supported because the full circumcision service is performed. Modifier-63applies to procedures performed on infants less than 4 kg for certain CPT codes when applicable, but it is not universally appended and is not the best answer here given typical CPC exam expectations for standard newborn circumcision technique identification. Therefore,54160is correct.

The procedure involves a tympanoplasty with a radical mastoidectomy and removal of a cholesteatoma from the middle ear, including grafting of the eardrum without ossicular chain reconstruction.

Procedure Description:

Tympanoplasty.

Radical mastoidectomy.

Removal of cholesteatoma from the middle ear.

Grafting technique used to repair the eardrum without ossicular chain reconstruction.

1. Procedure and CPT® Code Selection:

The emergency department physician placed an indwelling catheter into the lumbar region for continuous infusion for pain management with fluoroscopic guidance.

CPT® Code 62327 is appropriate for injection or catheter placement for continuous infusion of anesthetic or analgesic in the lumbar or sacral region using imaging guidance.

CPT® Code 77003 represents the fluoroscopic guidance used during the catheter placement, which is separately reportable in this case.

2. Rationale for Excluding Other Options:

Code 62326 (in options B and D) is for the injection or catheter placement without imaging guidance. Since fluoroscopic guidance was specifically mentioned, 62327 is the appropriate choice.

Code 77003 must be reported separately when fluoroscopy is used in conjunction with 62327 for pain management catheter placement.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, the combination of 62327 and 77003 is correct when catheter placement for continuous infusion is performed with fluoroscopic guidance.

Therefore, the correct answer is C. 62327, 77003.

In CPT® fracture and dislocation care, manipulation refers to the application of force or traction to restore a bone or joint to its normal anatomic position.

This is a key distinction between with manipulation and without manipulation, which directly affects CPT code selection (e.g., 23505 vs. 23500).

Manipulation may be performed closed (no incision) or open (with incision).

To determine the correct anesthesia code for a cesarean delivery with specific conditions, we review the following codes:

01961 is defined as "Anesthesia for cesarean delivery only," which aligns with this scenario, as the patient is admitted for a cesarean section.

01960 refers to anesthesia for a vaginal delivery, which does not apply here as the delivery is via cesarean.

01967 is for "Anesthesia for planned vaginal delivery," which also does not apply due to the cesarean route.

01958 is used for planned vaginal delivery that may involve a complicated scenario, but since the procedure is a cesarean section, this code is not appropriate.

Given that the patient is in labor for a cesarean section and has had a previous external cephalic version, 01961 is the correct answer.

For the excision of an 11 cm lesion with a rotation flap repair, the appropriate CPT codes are 14001 for the adjacent tissue transfer or rearrangement (12 sq cm flap) and 11606-51 for the excision of a malignant lesion including margins, face, ears, eyelids, nose, lips; excised diameter over 4.0 cm. Modifier 51 indicates multiple procedures. The detailed operative report specifies the lesion size and the technique used, justifying these codes.

For the injections, CPT® code 64642 is used for chemodenervation of one extremity; 64643 for each additional extremity, and 64647 for chemodenervation of muscles in the paraspinal region. The modifier -50 is added to 64642 and 64643 to indicate bilateral procedures. According to CPT® guidelines, when multiple sites are treated, each site is coded separately, and appropriate modifiers are used.

CPT code 11102 is for punch biopsy of skin, including simple closure. CPT code 12001-51 is for simple repair of superficial wounds, with modifier 51 indicating multiple procedures. ICD-10-CM code D49.2 is used for a neoplasm of unspecified behavior of the bone, soft tissue, and skin. This coding accurately reflects the punch biopsy and simple repair performed on the lesion.

Under HIPAA (Health Insurance Portability and Accountability Act), PHI stands for Protected Health Information. It includes any individually identifiable health information related to a patient’s health status, provision of healthcare, or payment for healthcare. Protection of PHI is a key compliance topic on the CPC exam.

The operative report documents amalignant lesion excision(basal cell carcinoma) on theright forearmfollowed by reconstruction with anadjacent tissue transfer (rotation flap)afterfrozen sectionconfirmed clear margins. In CPT, when a defect is repaired withadjacent tissue transfer/rearrangement, the flap code includes the work ofexcision (including necessary undermining and preparation of the recipient site)performed as part of creating and closing the defect; therefore the malignant excision code (e.g.,11606) isnot separately reportedin this same session when the excision is integral to the flap repair. Code selection for adjacent tissue transfer is based on theanatomic siteand thetotal defect area (primary + secondary defects). The documentedtotal area is 8 sq cm, and the site is theforearm (arm/leg grouping). For arms/legs,10 sq cm or lessis reported with14020. Codes14040apply to a different anatomic region grouping and do not match the forearm. Frozen section pathology/margin control does not change the primary surgical coding here. Therefore, report14020 only.

CPT code 19081 is used for percutaneous biopsy of breast(s) using stereotactic guidance, which includes the placement of a localization device and imaging of the biopsy specimen when performed. This accurately describes the procedure performed on the right breast with the placement of a Gelmark clip using stereotactic imaging. The other codes either describe open biopsies or separate procedures that are not applicable here.

CPT code 99450 is used for the examination of a patient for the purpose of establishing medical baseline information or for insurance purposes. Since Eric's primary care provider completed the required physical exam documentation for his life insurance policy, this is appropriately reported with code 99450. References: CPT® Professional Edition (current year), AMA.

42820 = Tonsillectomy and adenoidectomy, under age 12

J35.03 already includes chronic tonsillitis and adenoiditis

Hypertrophy is included and not separately coded

1. Procedure and CPT® Code Selection:

The patient underwent a partial nephrectomy (removal of part of the left kidney) via a laparoscopic approach.

CPT® Code 50543 is specifically used for a laparoscopic partial nephrectomy, which is an accurate description of this procedure.

2. Rationale for Excluding Other Options:

Code 50548 is used for a laparoscopic radical nephrectomy, which involves the complete removal of the kidney and surrounding structures; therefore, it does not apply to this partial nephrectomy.

Code 50220 represents an open partial nephrectomy, not a laparoscopic approach, and is therefore incorrect for this procedure.

Code 50546 is for a laparoscopic radical nephrectomy with bilateral removal of kidneys, which is not applicable in this case where only a partial removal of the left kidney was performed.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate that the use of 50543 is appropriate for any laparoscopic partial nephrectomy, regardless of the laterality, and it specifically identifies laparoscopic technique over open surgery.

Therefore, based on CPT® guidelines, the correct answer is C. 50543.

1. Procedure and CPT® Code Selection:

The physician administered the MMRV (measles, mumps, rubella, and varicella) vaccine subcutaneously and dose 3 of Hepatitis B vaccine intramuscularly. The physician also provided counseling on routine immunizations.

CPT® Code 90460 is used for immunization administration with counseling by the physician for patients 18 years or younger for the first or only component of each vaccine.

CPT® Code 90461 is used for each additional component in a vaccine with counseling.

90710 is the code for the MMRV vaccine.

90744 is the code for the Hepatitis B vaccine (pediatric).

2. Application of 90460 and 90461:

For the MMRV vaccine (which has four components: measles, mumps, rubella, and varicella), 90460 is reported once for the first component, and 90461 is reported three times (once for each additional component).

For the Hepatitis B vaccine, 90460 is reported again since it is a separate vaccine with one component.

3. Rationale for Excluding Other Options:

Option A (90471, 90472 x 4, 90707, 90746) uses codes for vaccine administration without counseling and incorrect vaccine codes (90707 for MMR instead of MMRV and 90746 for adult Hepatitis B instead of pediatric).

Option B and Option D also contain incorrect vaccine codes and do not correctly apply the counseling administration codes.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 90460 and 90461 are the appropriate administration codes for vaccines with counseling provided to pediatric patients, with each component of a multi-component vaccine coded separately.

Therefore, the correct answer is C. 90460 x 2, 90461 x 3, 90710, 90744.

To accurately code this emergency department visit, we need to assess the three key components: history, examination, and medical decision making (MDM).

History:

The documentation supports an expanded problem-focused history. This includes a chief complaint, a brief history of present illness (HPI), a review of systems (ROS) with pertinent positives and negatives, and a past medical history.

Examination:

The examination is also expanded problem-focused. The physician focused on the relevant systems (constitutional, HENT, respiratory) and documented specific findings related to the chief complaint (appears tired).

Medical Decision Making:

The MDM complexity is low. The physician is assessing a new problem (shortness of breath and weakness) with a low level of risk. No further testing or treatment is documented in this encounter.

Based on these components, 99283 is the most appropriate code.

Why other options are incorrect:

99282: Requires a problem-focused history and examination, which is less comprehensive than what was documented.

99284 and 99285: Require a higher level of MDM (moderate or high complexity) and/or a more detailed examination. The documentation doesn't support this level of service.

In medical billing, Place of Service (POS) code 31 is used to indicate that a service was performed in a skilled nursing facility (SNF). POS codes are standardized by the Centers for Medicare & Medicaid Services (CMS) to specify the location where services are provided.

A. 32 refers to a nursing facility (NF), which is different from a skilled nursing facility in terms of the level of care provided.

B. 20 indicates urgent care facility.

C. 22 is used for outpatient hospital services.

Thus, the correct answer is D. 31 for a skilled nursing facility.

This is a subsequent nursing facility care visit.

MDM Analysis (2021+ E/M Guidelines):

Problems: Multiple chronic conditions → Moderate

Data: 4 labs + telemetry → Moderate

Risk: Prescription drug management → Moderate

99309 – Subsequent nursing facility care, moderate MDM

Why others are incorrect:

99307 / 99308 – Low complexity

99305 – Initial nursing facility care

99393 = Preventive visit, established patient, age 5–11

Preventive codes are based on age and patient status, not time since last visit

98012 = Telephone E/M, 11–20 minutes

99447 is for interprofessional consults, not patient calls

HCPCS LEVEL II

11765 = Excision of nail fold (wedge excision), ingrown toenail

TA = Left great toe

Other codes are incorrect:

11730 = Partial nail avulsion

11750 = Nail excision

11755 = Biopsy

Correct answer: 11765-TA

The anesthesia code for an axillary block for procedures on the upper arm and elbow, which includes the monitoring by the anesthesiologist throughout the procedure, is 01830. This code is appropriate for anesthesia for all procedures on nerves, muscles, tendons, fascia, and bursae of the shoulder and axilla.

CPT® Professional Edition, AMA

Anesthesia Coding Guidelines

Cholecyst- = gallbladder

Entero- = intestine

-ostomy = creation of an opening

Cholecystenterostomy is the correct term for surgically creating a connection between the gallbladder and the intestine.

This aligns with surgical terminology commonly tested in the CPT® digestive system section (40000–49999).

Cystourethroscopy: This is a procedure that involves the use of a cystoscope to look inside the urethra and bladder.

Pyeloscopy: Involves the examination of the upper urinary tract, typically done through the cystoscope.

Lithotripsy: A procedure that uses shock waves or a laser to break up stones in the kidney, bladder, or ureter.

Indwelling stent insertion: A procedure to place a stent in the ureter to help urine flow from the kidney to the bladder.

52356: Cystourethroscopy with ureteroscopy and/or pyeloscopy; with lithotripsy (ureteral catheterization and/or ureteral stent placement).

The code 52356 includes all components mentioned: cystourethroscopy, pyeloscopy, lithotripsy, and stent insertion performed in the same operative session.

80324 – Drug test(s), definitive, qualitative or quantitative, LC/MS; acetaminophen

LC-MS = definitive testing

Acetaminophen is specifically identified by 80324

Why others are incorrect:

60143 / 80299 – Therapeutic drug assays (obsolete or nonspecific)

B0329 – HCPCS code (not appropriate here)

90471/90472 = Administration without counseling

90707 = MMR

90746 = Hepatitis B, adult

The diagnosis “tracheal stenosis present from birth” is acongenital malformation, which is coded withQ32.1(congenital stenosis of trachea) rather than an acquired tracheal disorder code. For anesthesia coding, tracheoplasty is a major airway/tracheal surgical procedure and maps to the appropriateairway/trachea anesthesiacategory represented by00320in the answer set. Because the patient is aninfant (6 months old), anesthesia qualifies for the extreme age add-on99100(anesthesia for patient of extreme age, under 1 year or over 70 years). Options includingJ39.8reflect an acquired/other tracheal disorder category rather than congenital stenosis, which conflicts with “from birth.” Options that omit 99100 miss the age-related qualifying circumstance. CPC exam strategy: always code congenital conditions withQ-codeswhen documented as present from birth, and remember99100for patients<1 yearwhen anesthesia qualifying circumstances are reported. Therefore,00320, 99100, Q32.1is correct.

1. Procedure and CPT® Code Selection:

The scenario describes the excision of a 5 cm tumor located in the left lower quadrant of the abdominal wall. The tumor was excised down to the dermis and subcutaneous layers and removed using electrocautery.

Code 22903 is appropriate for the excision of a soft tissue tumor in the abdominal wall greater than 5 cm, making it the correct CPT® code.

Code 22901 applies to the excision of a soft tissue tumor in the abdominal wall but only for tumors 5 cm or less. Given that the tumor in this case is exactly 5 cm, it meets the threshold for 22903, which is more appropriate here.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code D49.2 is used for a neoplasm of unspecified behavior in the abdominal area, reflecting the fact that the pathology report is pending to determine if the tumor is malignant.

Code C76.2 would be incorrect because it is for malignant neoplasms of unspecified abdominal areas, which we cannot confirm based on the initial excision. Similarly, R19.04 (indicating a mass in the abdominal region) is a symptom code and is not appropriate for a definitive diagnosis when a neoplasm code (D49.2) exists.

3. AAPC and CPT® Coding Guidelines:

Per AAPC coding guidelines, the size of the tumor is critical in selecting the correct excision code for abdominal wall neoplasms. Additionally, if the tumor’s pathology is not confirmed as malignant, it is coded as a neoplasm of unspecified behavior until further details are known.

Therefore, based on CPT® and ICD-10-CM coding guidelines, the verified answer is B. 22903, D49.2.

CPT code 99385 is used for initial comprehensive preventive medicine evaluation and management of an individual, including a detailed history and examination, and anticipatory guidance. Since additional documentation and treatment for non-inflamed lesions are provided, an additional E/M service code 99203 with modifier -25 (significant, separately identifiable evaluation and management service by the same physician on the same day) is appropriate to indicate both services were rendered. References: CPT® Professional Edition (current year), AMA.

A41.52 = Sepsis due to Enterococcus.

When the organism is specified, a combination code is used.

No additional code for severe sepsis is documented.

1. Procedure and CPT® Code Selection:

The patient had a cochlear implant placed in the left ear and is now seeing the audiologist for initialization and programming of the implant.

CPT® Code 92603 is specific for initial programming of a cochlear implant for patients younger than 12 years old. This includes the setup and initial adjustments required for the cochlear implant, making it the correct code.

2. Rationale for Excluding Other Options:

Code 92626 is used for evaluating auditory function with the cochlear implant, focusing on assessment rather than programming, and is therefore incorrect for this programming session.

Code 92630 is for aural rehabilitation following cochlear implant, which does not apply to the programming/initiation stage.

Code 92604 is for subsequent programming sessions after the initial programming and is therefore not applicable for the first-time programming.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 92603 is the appropriate code for initial programming of a cochlear implant in children under 12 years of age.

Therefore, the correct answer is D. 92603.

In medical terminology,“-graph”refers to aninstrument used to record(or produce a record), while“-gram”refers to therecord/image produced, and“-graphy”refers to theprocess of recording. This set is frequently tested because the terms look similar. Example: anelectrocardiographis the instrument; anelectrocardiogram (ECG/EKG)is the tracing produced;electrocardiographyis the act of recording. The distractors are surgical suffixes:“-desis”typically indicates surgical binding/fusion, and“-rrhaphy”indicates surgical repair by suture. “Z-plasty” is a plastic surgery technique; “instrument used for Z-plasty” is not a standard suffix definition. For CPC-style questions, the safest approach is to memorize the trio:graph (instrument)/gram (record)/graphy (process). That pattern also helps with radiology terms (mammogram, angiography) and diagnostic testing vocabulary.

47000 = Percutaneous liver biopsy

77021 = MRI guidance for needle placement

Multiple cores are included in the biopsy code

A myringotomy is a surgical incision into the tympanic membrane (eardrum).

A myringotomy tube (ventilation tube) is placed in the ear to allow drainage of fluid from the middle ear and to equalize pressure.

Therefore, the correct answer is A. Ear.

47563: Laparoscopic cholecystectomy with cholangiography is coded as 47563. The report details the laparoscopic removal of the gallbladder with intraoperative cholangiography.

74300-26: The radiological supervision and interpretation for the cholangiography is coded as 74300 with modifier -26 (Professional Component) since the interpretation was done by the physician.

The patient has undergone a left total knee arthroplasty and subsequently received a femoral nerve block for postoperative pain management. CPT code 01402 is used for anesthesia for total knee arthroplasty. Code 64447-59-LT is for a femoral nerve block (single injection) for postoperative pain management, with modifier 59 indicating a distinct procedural service and LT indicating the left side. Therefore, the appropriate codes are 01402 and 64447-59-LT.

Procedure: Abdominal aorta catheterization and selective placement in the celiac trunk for angiography.

CPT® Codes:

36246: This code is for the catheter placement in the abdominal aorta.

75726-26: This code represents the abdominal angiography with supervision and interpretation, with the -26 modifier indicating the professional component.

Code Selection Justification: The procedure involves the catheterization of the abdominal aorta and the specific imaging performed with supervision and interpretation.

1. Procedure and CPT® Code Selection:

The patient underwent a percutaneous needle biopsy of the liver with ultrasound guidance to assess primary biliary cirrhosis.

Code 47000 is the CPT® code for a percutaneous liver biopsy. This code encompasses the biopsy procedure itself.

Ultrasound guidance is commonly inherent to biopsy procedures, and guidance is not separately reported if the main code (47000) includes the technique used.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code K74.5 is the correct code for primary biliary cirrhosis, which is specifically indicated in this case.

K74.3 is the code for other specified cirrhosis of the liver but is less specific than K74.5, making K74.5 the appropriate choice here.

3. Exclusion of Other Codes:

Code 47100 (option A) is for an open liver biopsy, which does not apply to this percutaneous procedure.

Codes 10005 (biopsy with imaging guidance) and 76942 (ultrasound guidance) would be redundant or incorrect since the main procedure code, 47000, sufficiently describes a percutaneous liver biopsy.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines state that guidance is included in certain biopsy codes when performed for the targeted organ, such as in 47000 for a liver biopsy.

Therefore, based on CPT® and ICD-10-CM coding rules, the correct answer is C. 47000, K74.5.

Pressure ulcer excision with bone involvement → CPT 15937 (sacral, with ostectomy)

Stage 4 pressure ulcer → L89.156 (sacral region with necrosis of bone)

A tympanoplasty repairs aperforated tympanic membrane. The key phrase “doesnotremove the mastoid” means this istympanoplasty without mastoidectomy, which is correctly represented by69631in the answer set. Codes that include mastoid work (or represent different tympanoplasty variants) are incorrect because the documentation explicitly states the mastoid was not removed. Diagnosis coding should reflect both thechronic otitis mediaand theperforation. In the options,H66.92represents otitis media (as offered) andH72.92represents perforation of the tympanic membrane (as offered). Although the clinical story specifies the left ear, the provided diagnosis options do not include laterality; on CPC-style questions, you choose the best match among the answer choices. Therefore, the correct combination within this question’s choices is69631 with H66.92 and H72.92, matching tympanoplasty without mastoidectomy plus the documented conditions.

1. Procedure and CPT® Code Selection:

The patient requires a surgical nasal sinus endoscopy to repair a cerebrospinal fluid (CSF) leak caused by a skull fracture that resulted in CSF draining into the nasal passage.

Code 31291 is the correct CPT® code for an endoscopic repair of a cerebrospinal fluid leak in the sphenoid sinus. This procedure code is appropriate because it specifically addresses surgical endoscopy for CSF leak repair in the sinus region.

Other codes provided, such as 31287 (nasal/sinus endoscopy with balloon dilation) and 31235 (nasal endoscopy with biopsy), do not match the description for surgical repair of a CSF leak and are therefore inappropriate for this case.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code S02.19XA is used to describe a fracture of the anterior cranial base, which fits the described injury of the skull with cerebrospinal fluid leakage.

External cause code V47.5XXA is used for motor vehicle accidents involving a car hitting a stationary object.

Y92.411 is the appropriate code to describe the location of the accident as a highway.

3. Exclusion of Additional Procedure Codes:

There is no need for a second endoscopy code or a modifier, as 31291 fully describes the endoscopic repair procedure for the CSF leak.

4. AAPC and CPT® Coding Guidelines:

Per AAPC guidelines, procedure codes for sinus endoscopy are chosen based on the specific type of intervention (e.g., CSF leak repair). The guidelines for ICD-10-CM stress including external cause codes and location codes for trauma cases related to motor vehicle accidents.

Thus, the correct answer based on CPT® and ICD-10-CM coding standards is B. 31291, S02.19XA, V47.5XXA, Y92.411.

The clinical scenario involves a diagnostic angiography (not separately reportable in this case as the therapeutic intervention occurs in the same session and the diagnosis is already known) and a percutaneous transluminal angioplasty (PTA) with stent placement in the left iliac artery.

To code this correctly:

CPT Code 37267: Transluminal stent placement(s), includes angioplasty within the same vessel, when performed; iliac artery.

This code includes the angioplasty if it is performed in the same vessel as the stent (which is true here — both procedures are done in the left iliac artery).

Since angioplasty is inherent to the stenting (to open the narrowed vessel before stent placement), only the stent code is reported.

No need to report angioplasty separately (e.g., 37263) when performed in the same vessel as the stent.

Other options explained:

A. 37267, 37263 – Incorrect. 37263 (angioplasty in the iliac artery) would only be reported if angioplasty was done in a separate iliac artery segment without stenting. Reporting both codes for the same vessel would be unbundling and against CPT/NCCI guidelines.

B. 37258, 37254 – Incorrect. These codes relate to renal artery procedures, not iliac artery.

C. 37258 – Also incorrect, as this refers to renal stent placement, not iliac.

Official CPT® Guideline Reference:

In the CPT® manual (Category I codes, 37220–37235), specific instructions state that angioplasty is included when performed in the same vessel as a stent and should not be reported separately.

For a follow-up examination after the removal of polyps with no new polyps found, the appropriate diagnosis codes are:

Z09: Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm.

Z86.010: Personal history of colonic polyps.

Using Z09 indicates that the follow-up exam is to check the patient after treatment, and Z86.010 indicates a history of colonic polyps, which is relevant to the patient's medical history.

1. E/M Code Category Selection:

The patient was placed in observation care on 12/2/20XX for an acute asthma exacerbation and stayed in observation for a total of 16 hours, with discharge occurring on 12/3/20XX.

The appropriate E/M category for patients in observation care for a period that includes both admission and discharge on separate calendar dates is "Hospital Inpatient or Observation Care Services", with specific codes for admission and discharge on different dates.

2. Code Range and Specific Codes:

Code Range 99234-99236 applies to cases where observation care includes both admission and discharge, particularly when they occur on different calendar days and the total duration of care is under 24 hours.

For discharge on the subsequent day, 99238-99239 (Hospital Inpatient or Observation Discharge Services) applies, depending on the time spent on discharge.

3. Rationale for Excluding Other Options:

Option B and Option D include Initial Hospital Inpatient or Observation Care codes (99221-99223), which are typically used for admissions to inpatient care rather than for observation care scenarios as presented here.

Option C incorrectly combines Subsequent Inpatient or Observation Care codes (99231-99233), which are used for follow-up days rather than discharge services.

4. AAPC and CPT® Coding Guidelines:

According to CPT® guidelines, the 99234-99236 code range is used when observation care requires both admission and discharge on different dates, and 99238-99239 is appropriate for discharge services.

Therefore, the correct answer is A. Hospital Inpatient or Observation Care Services (Including Admission and Discharge Services) (99234-99236) and Hospital Inpatient or Observation Discharge services (99238-99239).

1. Procedure and CPT® Code Selection:

The scenario describes the removal and replacement of an inflatable penile prosthesis due to erectile dysfunction.

CPT® Code 54416 is specifically used for the removal and replacement of a multi-component inflatable penile prosthesis. This code accurately describes the procedure performed.

2. Rationale for Excluding Other Options:

Code 54401 represents the initial insertion of a multi-component inflatable penile prosthesis but does not cover removal and replacement, making it inappropriate for this scenario.

Code 54400 is for the insertion of a non-inflatable (malleable) penile prosthesis, which does not apply here as the prosthesis is inflatable.

Code 4417 does not exist in the CPT® coding system and is likely a typo or incorrect option.

3. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 54416 is the correct code when an inflatable prosthesis requires both removal and replacement, without the need for additional modifiers for this procedure.

Therefore, the correct answer based on CPT® guidelines is D. 54416.

For a physician who owns the equipment and interprets the chest X-rays (both frontal and lateral views), code 71046 is used. This code includes both the technical and professional components, as the equipment is owned by the physician group and the physician also provides the interpretation.

Burn coding requires (1) code each burn site bylocation, laterality, and degree, and (2) add aTBSAcode when appropriate. The patient hasthird-degree burnsof both thighs (right and left), so the correct site/degree codes areT24.311A(third-degree burn of right thigh, initial encounter) andT24.312A(third-degree burn of left thigh, initial encounter). He also hassecond-degree burnsof the right anterior chest wall and the upper back, reported withT21.21XA(second-degree burn of chest wall, initial encounter) andT21.23XA(second-degree burn of back wall, initial encounter). TBSA is24%(falls in the 20–29% category), andthird-degree is 10%(falls in the 10–19% third-degree category), so the correct TBSA code isT31.21. Option D matches the required site/degree codes and the correct TBSA/third-degree percentage code pairing.

Repair of wound dehiscence → CPT 13160 (complex repair, secondary closure)

Occurs during global period and is unplanned → Modifier -78

Modifier -58 is for staged or planned procedures.

The gallbladder is part of the digestive system. It stores and concentrates bile, which aids in the digestion of fats.

It works closely with the liver and biliary tract, all of which belong to the digestive system, making C the correct answer.

69200 – Removal of foreign body from external auditory canal; without anesthesia

Correct for simple removal using forceps

Patient tolerated procedure without anesthesia

Why Other Options Are Incorrect:

69110 / 69105 – Middle ear procedures

69205 – Removal with general anesthesia

45346 = Sigmoidoscopy with ablation (reported once)

K63.5 = Polyp of colon

According to ICD-10-CM Guidelines, I11A.0 (Resistant hypertension) is used to indicate hypertension that remains uncontrolled despite the use of multiple antihypertensive medications. Resistant hypertension is coded to highlight the severity of the patient’s condition and the difficulty in managing their blood pressure. This code is added as a secondary code to reflect the persistent elevation of blood pressure despite medication.

A. I10 (Essential hypertension) is a general code for primary hypertension but does not specify resistance to treatment.

B. A code from category I27 is related to pulmonary heart diseases, not directly related to hypertension management issues.

D. A code from category I16 (Hypertensive crisis) is used for hypertensive emergencies or urgencies, which are acute episodes, not persistent uncontrolled hypertension despite treatment.

Thus, the correct answer is C. I11A.0, Resistant hypertension.

Procedure: Gross and microscopic examination of a newborn autopsy.

In CPT® Surgery Guidelines, a "separate procedure" code is used to identify a service that is typically performed as part of a larger procedure and should not be coded separately when it is an integral component of that primary service. However, it may be reported independently if it is performed alone or is unrelated to the primary procedure.

A. is true because a separate procedure may be reported if it is performed independently or is unrelated to the primary procedure.

B. is true, as "separate procedure" codes are not reported in addition to the code for the primary procedure when they are part of the total procedure.

C. is correct because "separate procedure" designation indicates that the service is often part of a more comprehensive procedure but can be reported separately when performed alone.

D. is false because modifier 79 is not used for unrelated "separate procedures." Instead, modifier 59 is typically used to indicate a "distinct procedural service" when reporting a separate procedure that is unrelated to the primary service.

Therefore, the correct answer is D. To identify a service designated as a "separate procedure" that is reported with an unrelated primary service, append modifier 79 to the code.

44970 = Laparoscopic appendectomy

K36 = Chronic appendicitis

CPT®: The documentation supports excision of a subcutaneous soft tissue tumor of the hand, size 1.5 cm.

26111 = Excision of tumor/soft tissue of hand or finger, subcutaneous, 1.5 cm or less

26115 would be for a larger size range (not supported by “1.5 cm” in the question).

ICD-10-CM: Pathology confirms subcutaneous hemangioma (benign vascular tumor).

D18.01 = Hemangioma of skin and subcutaneous tissueCodes D21.01/D21.11 are benign neoplasm of connective/soft tissue categories, but the most accurate match here (and the one reflected in the answer choices) is D18.01 for hemangioma of skin/subcutaneous tissue.

Typing correction applied: the options showed “018.01”; the correct ICD-10-CM format is D18.01.

CPT® code 15786 is used for abrasion treatment of a single lesion (e.g., for keratosis) through techniques like dermabrasion (lightly sanding the skin's surface). When treating multiple lesions in this manner, each lesion treated should be coded individually.

Since the patient has 5 keratosis lesions treated through sanding, 15786 x 5 accurately represents the procedure for each lesion.

Explanation of other options:

A. 15787 x 5: Incorrect because 15787 is designated for dermabrasion of "additional lesions" and would be used in conjunction with 15786, not alone.

B. 15786, 15787: Incorrect, as it does not account for all five lesions treated.

C. 15786, 15787 x 4: Incorrect, as 15787 is used only when performed in addition to 15786, not as a replacement for each additional lesion.

Therefore, the correct answer is D. 15786 x 5, which accurately reports the treatment of all five lesions.

ICD-10-CM guidelines state that healing pressure ulcers are coded as the stage documented.

L89.624 = Pressure ulcer of left heel, stage 4

Stage 4 ulcers involve full-thickness tissue loss and are commonly referenced in exam scenarios involving treatment of healing ulcers

Unspecified stage or laterality codes are not appropriate when documentation supports specificity.

94060 = Spirometry pre- and post-bronchodilator

94010 = Baseline spirometry

J45.21 = Mild intermittent asthma with exacerbation

End-Stage Renal Disease (ESRD) is a condition in which the kidneys fail to work effectively to remove waste products and excess fluids from the blood. This primarily affects the genitourinary system, which includes the kidneys, ureters, bladder, and urethra. Patients with ESRD often require dialysis or a kidney transplant.

ICD-10-CM (current year), Chapter 14: Diseases of the Genitourinary System (N00-N99).

Medical terms here are very literal.Peri-meansaround,cardirefers to theheart, and-itismeansinflammation. Sopericarditisis inflammation of thepericardium, thefibrous sac surrounding the heart. “With effusion” indicatesfluid accumulationin that pericardial space (pericardial effusion), which can be clinically important because significant effusion may impair heart filling (tamponade risk), but the question is strictly asking which structure is inflamed. Distractors map to other “card-” terms:myocardium(heart muscle) would be “myocarditis,”endocardium(inner lining of chambers/valves) would be “endocarditis,” and blood vessels supplying the heart arecoronary arteries(inflammation would not be termed pericarditis). On CPC exams, identifyingprefix + root + suffixis the fastest method: peri (around) + cardi (heart) + itis (inflammation) → pericardium inflamed.

CPT Code 55706: Biopsy, prostate; needle, transperineal, stereotactic template guided saturation sampling, including imaging guidance.

This code accurately describes the procedure performed. The documentation clearly states that a stereotactic template was used to guide the biopsy needles, and multiple samples were taken (saturation biopsies). This code includes imaging guidance.  

CPT Code 76942: Ultrasonic guidance for needle placement (e.g., biopsy, aspiration, injection, localization device), imaging supervision and interpretation.  

Although 55706 includes imaging guidance, code 76942 is also reported separately because the transrectal ultrasound provided initial diagnostic images and was then used for guidance during the biopsy. This is supported by the documentation which states "Using a B & K ultrasound probe, a transrectal ultrasound of the prostate was obtained. Once this was done...a biopsy needle is inserted into the prostate...under ultrasound guidance." This indicates distinct uses of the ultrasound.

Important Note: While some sources suggest that 76942 and the diagnostic transrectal ultrasound code (76872) are bundled, it's crucial to consult the latest National Correct Coding Initiative (NCCI) edits for the most up-to-date guidance.

The Office of Inspector General (OIG) operates under the Department of Health and Human Services (HHS) and is specifically responsible for detecting, investigating, and preventing fraud, waste, and abuse in federal healthcare programs such as Medicare and Medicaid.

The CPT® codes for skin biopsies depend on the method used and the location of each lesion. Here, the scenario includes:

1. Two punch biopsies on the trunk: CPT® code 11104 is used for a full-thickness punch biopsy of the skin, and 11104 x 2 is appropriate since two lesions on the trunk were sampled.

2. One partial-thickness shave biopsy on the forehead: CPT® code 11102 is used for a tangential (shave) biopsy, which captures a partial-thickness sample, appropriate for the forehead lesion.

Explanation of other options:

B. 11104, 11105, 11103: Incorrect, as 11105 is an add-on for additional punch biopsies at separate sites but not used here.

C. 11104, 11103 x 2: 11103 is an add-on code for additional shave biopsies, which does not apply to the punch biopsies on the trunk.

D. 11104, 11102 x 2: Incorrect, as 11102 is only used for the shave biopsy, not for the punch biopsies.

When a patient experiences an underdose of insulin due to an insulin pump malfunction, the primary reason for the encounter would be the malfunction itself, which is coded first. The resulting hyperglycemia or hypoglycemia due to the pump failure is a secondary condition. According to ICD-10-CM guidelines, the code for the mechanical complication of the pump (T85.633-) is sequenced first, followed by a code for the diabetes with complication (E11.65 for type 2 diabetes with hyperglycemia).

ICD-10-CM (current year), Chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes (S00-T88), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.4.

11200 = removal of up to 15 skin tags

11201 = each additional 10 lesions or part thereof

26 lesions = 15 + 11 → 11201 ×2

60220 = Total lobectomy, unilateral thyroid

60500 = Parathyroidectomy (single gland)

Modifier -59 is appropriate to indicate a distinct procedure

The procedure described involves a LeFort I reconstruction, which is a type of orthognathic surgery performed to correct deformities of the midface. In this scenario, the surgeon performed the reconstruction in two pieces, moving the upper jawbone forward and repositioning the teeth of the maxilla. According to the CPT® guidelines, CPT code 21146 describes a LeFort I (maxilla only) osteotomy, two-piece segment, including bone grafts (includes obtaining autografts). This code matches the description provided.

Heyman capsules are applicators used ingynecologic brachytherapy, classically forintracavitary uterineplacement as part of internal radiation therapy. CPT distinguishes between prostate brachytherapy services and gynecologic applicator placements.55875is associated with prostate brachytherapy procedures, and57155is for insertion of uterine tandem and/or vaginal ovoids (a different applicator system). The code that specifically aligns withinsertion of Heyman capsulesis58346. CPC exam strategy: when a question names a specific device/apparatus (like Heyman capsules), it is usually pointing to avery specific CPT code. Also, keep the anatomic system straight—Heyman capsules are not a prostate service and not simply a generic “radiation therapy” code; they are a named gynecologic brachytherapy applicator insertion. Therefore, among the given options,58346is the correct report.

37267 = Iliac artery stent placement

Angioplasty is bundled into the stent code

Supernumerary digit removal coding depends on whether the extra digit hasbone/jointor is asoft-tissue tag/nubbin. The left-hand extra digit includes ametacarpal bone with a joint, so it is treated as removal of an accessory digit with bony involvement, reported with26910(removal of extra digit, hand/foot;withbone and joint reconstruction elements implied by the code family context). Because it is theleftside, append-LT. The right-hand extra digit is described as anubbin with no bony structure, removed bysimple excision—this aligns with askin tag-likeremoval code,11200, for removal of benign skin tags/lesions by simple excision (as represented in the answer options) with-RTfor laterality. You should not bill both sides with a single “-50” here because the procedures arenot the sameon each side (bony digit vs soft-tissue nubbin). Therefore,26910-LT and 11200-RTis correct.

1. Procedure and CPT® Code Selection:

The provider performed both a bronchoscopy and a microlaryngoscopy to evaluate the patient’s airway due to respiratory distress and stridor.

Code 31622 is used for a diagnostic bronchoscopy, which includes the inspection of the trachea, carina, and bronchial structures. Since the bronchoscopy was diagnostic and no additional therapeutic procedures were performed, this is the appropriate code.

Code 31526 is for direct laryngoscopy with the use of an operating microscope or telescope (microlaryngoscopy). This code is appropriate given the use of a Parson’s laryngoscope and magnifying telescope to inspect the larynx.

2. Modifier 51:

Modifier 51 is added to 31526 to indicate that it was performed in conjunction with another procedure (31622, bronchoscopy). Modifier 51 denotes multiple procedures without the necessity of a separate incision.

3. Exclusion of Code 69990:

Code 69990 is used for the use of an operating microscope in microsurgery but is not coded separately when the procedure (such as microlaryngoscopy) already includes visualization with a microscope or telescope as part of the CPT® descriptor. Thus, 69990 is not separately reported in this scenario, per CPT® guidelines.

4. AAPC and CPT® Coding Guidelines:

The guidelines specify that when visualization or microlaryngoscopy is inherently part of the procedure (as in 31526), 69990 should not be billed separately. Also, the use of Modifier 51 for multiple procedures in the same session is appropriate.

Therefore, the verified answer, following the CPT® and AAPC coding rules, is A. 31622, 31526-51.

27380 = Repair, quadriceps muscle

S76.311A = Strain of muscle, fascia, tendon of right thigh, initial encounter

Code selection is based on specific muscle group and laterality

29827: Arthroscopic rotator cuff repair is correctly coded as 29827.

29828: Arthroscopic biceps tenodesis is an additional procedure and should be coded as 29828 with modifier -51 (Multiple Procedures).

29824: Arthroscopic claviculectomy (partial resection of the distal clavicle) is coded as 29824 with modifier -51.

29826: Arthroscopic subacromial decompression, including coracoacromial ligament release, is coded as 29826.

All these procedures were performed arthroscopically and documented in the operative report, justifying the use of these codes and the use of modifier -51 for multiple procedures.

CPT® Professional Edition, AMA

The procedure performed is a bilateral screening mammogram with computer-aided detection (CAD). CPT code 77067 is for bilateral screening mammography with CAD. ICD-10-CM code Z12.31 is for an encounter for screening mammogram for malignant neoplasm of the breast. Z80.3 is for a family history of malignant neoplasm of the breast. Therefore, the correct coding is 77067, Z12.31, Z80.3. References: CPT® Professional Edition (current year), ICD-10-CM (current year).

For this scenario, two surgeons are working together, each as a primary surgeon. Therefore, the correct coding requires the use of the modifier -62, which indicates co-surgeons.

The transthoracic approach to excise the damaged portion of the vertebral body is coded with 63087.

The insertion of the bone graft and metal plate is coded with 63088.

Both codes are appended with modifier -62 to indicate that two surgeons worked together as primary surgeons on this case.

The described scope reaches thesigmoid colon, which is consistent with aflexible sigmoidoscopyrather than a full colonoscopy. The key therapeutic action is that the polyps were treated byablation(destruction), not snare excision or biopsy. CPT45346represents flexible sigmoidoscopy withablationof tumor(s), polyp(s), or other lesion(s). You report the sigmoidoscopy ablation codeoncefor the session; you do not multiply it by the number of polyps unless CPT instructions explicitly direct unit reporting (which is not the standard approach for these endoscopic therapeutic codes). For diagnosis, polyps in thesigmoid colonare coded asK63.5 (polyp of colon).K62.1is arectal polypcode and does not fit because the polyps are in the sigmoid colon. Therefore,45346withK63.5is correct. CPC exam tip: match thescope extent(sigmoid) and theremoval method(ablation).

This scenario describes apalatoplasty(repair of cleft palate) withclosure of the alveolar ridgeusing abone graft. CPT code42210is the code that captures palatoplasty withclosure of the alveolar ridgeand associated bone grafting work as part of the reconstructive procedure described. Because the bone graft is part of the defined palatoplasty service in this code concept, you donotseparately report a generic bone graft harvesting code such as20900in the way the answer options suggest. The distractor42200is associated with a more limited palate repair (not matching the alveolar ridge closure with graft detail), and42205does not reflect the specific alveolar ridge closure with bone grafting described in the question stem. CPC exam strategy: identify the mostcomprehensive cleft palate repairthat matches the documentation; when a CPT code description includes the specific additional work (like alveolar ridge closure with graft), code that single comprehensive service.

In the ICD-10-CM Tabular List,parentheses ( )are used to enclosenonessential modifiers, also described assupplementary words. These are words thatmay be present or absentin the diagnostic statement without affecting code assignment. This is exactly why parentheses are associated with synonyms, alternative wording, or explanatory phrases. If the provider documents the core diagnosis and the parenthetical term is missing, the code can still be correct; if the parenthetical term is present, it still points to the same code. By contrast, acolon (:)is used after an incomplete term that needs one or more additional terms to make it assignable.Brackets [ ]have other specific functions (such as enclosing synonyms in certain contexts and used with instructional content), but the standard CPC-tested definition for “synonyms/alternative wording/explanatory phrases” in the Tabular List points toparenthesesas nonessential modifiers. Knowing this distinction supports accurate code selection and reduces errors when provider wording varies.

The National Correct Coding Initiative (NCCI) was developed by CMS to:

Prevent unbundling

Define procedure-to-procedure (PTP) edits

Identify when modifiers (such as -59) may be appropriate

NCCI edits are critical for accurate CPT® coding and proper reimbursement.

99223 = Initial hospital/observation care with high time (75+ min) or high MDM

Prolonged service 99418 is bundled into observation services

The procedure described is flexible bronchoscopy with bronchial biopsy (biopsy taken from the bronchi/bronchial tubes).

31625 = Bronchoscopy, flexible, with biopsy (single or multiple)

Important CPC concept: when the CPT® descriptor is “single or multiple”, you code it once, even if multiple biopsies are taken.

31628 is for transbronchial lung biopsy, which is not what is described (the question specifies bronchial tubes/bronchial biopsies).Therefore, A is correct.

E08.3213 = Diabetes due to underlying condition with mild NPDR with macular edema, bilateral

E24.9 = Cushing’s syndrome (underlying condition)

Z79.84 = Long-term use of oral hypoglycemic drugs

Sequencing follows ICD-10-CM guidelines for secondary diabetes.

The prefix “sub-” means below or under.

Common examples include subcutaneous (below the skin) and sublingual (under the tongue).

This is a core concept tested under medical terminology on the CPC exam.

Procedure Coding (CPT®):

69910 – Labyrinthectomy, complete; transmastoid approach

Provider performed:

Mastoidectomy

Complete destruction/removal of semicircular canals, utricle, and saccule

This is a complete labyrinthectomy, not partial

69990 – Microsurgical techniques, requiring use of operating microscope

Separately reportable with otologic procedures

Modifier -51 not required (add-on code)

Diagnosis Coding (ICD-10-CM):

H81.391 – Peripheral vertigo, right ear

Correct laterality and condition

Why Other Options Are Incorrect:

69905 – Partial labyrinthectomy

R42 – Symptom code (dizziness), not used when definitive diagnosis exists

The CPT code 11960 is used for the insertion of tissue expanders for other than breast, which includes the scalp in this case. The procedure involves inserting the tissue expanders, closing the skin, and gradually increasing the volume of the expanders until a satisfactory outcome is achieved for repairing the scalp defect. The other options do not accurately describe the procedure performed on the scalp.

AMA's CPT® Professional Edition (current year)

A diagnostic mammogram performed on both breasts with computer-aided detection (CAD) is reported with CPT® code 77066. This code is used when CAD is utilized to further analyze the images for possible lesions, and it covers both breasts.

According to the CPT® guidelines for Repair (Closure), an intermediate repair includes the closure of a wound with one or more layers of subcutaneous tissue and superficial fascia in addition to the skin (epidermal and dermal) closure. It also involves extensive cleaning of the wound, which includes copious irrigation and the removal of particulate matter. This description fits the scenario provided in the question.

AMA's CPT® Professional Edition, Repair (Closure) guidelines.

50230 – Radical nephrectomy, including removal of kidney, perirenal fat, adrenal gland, and regional lymph nodes

Open approach with rib resection

Correct for extensive removal beyond simple nephrectomy

Why Other Options Are Incorrect:

50545 / 50543 – Laparoscopic/robotic approaches

50220 – Simple nephrectomy only

According to ICD-10-CM burn guidelines:

When burns of different degrees occur at the same site, only the highest degree is coded, not separate codes.

The other statements are true:

Necrosis is coded as a non-healed burn

Burn codes include electrical and radiation burns

The highest degree burn is sequenced first

62272 = Lumbar puncture with catheter for CSF drainage

77012 = CT guidance for needle placement

1. Procedure and CPT® Code Selection:

The patient underwent a pulmonary function test that included spirometry, vital capacity, breathing capacity, and flow volume measurements before and after bronchodilator administration.

CPT® Code 94060 is for spirometry, including the bronchodilator responsiveness testing, which involves capturing pre- and post-bronchodilator measurements. This code accurately reflects the testing performed.

CPT® Code 94010 is for spirometry testing without bronchodilator, which might be considered redundant in this case since 94060 encompasses spirometry testing with and without bronchodilator. However, some practices may code both, but generally, 94060 alone should suffice.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code J45.901 is used for unspecified asthma with acute exacerbation. This code is appropriate given that the diagnosis indicates intermittent asthma with exacerbation.

J45.21 represents mild intermittent asthma without the specification of exacerbation, making it less accurate than J45.901 in this context.

3. Rationale for Excluding Other Options:

Code 94070 (options B and C) is for bronchospasm provocation testing, which does not apply to standard pulmonary function testing with bronchodilator responsiveness.

Option D includes J45.21, which does not capture the exacerbation aspect and is therefore incorrect.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 94060 should be used when pre- and post-bronchodilator spirometry is performed, and J45.901 is appropriate for asthma with exacerbation.

Therefore, the correct answer is A. 94060, 94010, J45.901.

1. Procedure and CPT® Code Selection:

The patient required surgical intervention for severe ocular trauma involving removal of a foreign body from the posterior segment of the eye, suturing of the corneal laceration, and a pars plana lensectomy.

CPT® Code 65265 is for removal of a foreign body from the posterior segment of the eye without the use of a magnet. This code is appropriate for the removal of the metallic foreign body using retinal forceps.

CPT® Code 66852 covers the pars plana lensectomy, which was performed as part of the surgical treatment.

CPT® Code 65280 is used for repairing a corneal laceration with multiple perforations, which applies to the corneal suturing.

2. Modifiers:

Modifier RT is used to indicate that the procedures were performed on the right eye.

Modifier 51 is added to indicate multiple procedures performed during the same surgical session.

3. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code S05.51XA is appropriate for penetrating wound of the right eyeball with a foreign body in the posterior segment.

ICD-10-CM Code W31.1XXA is used to indicate that the injury was caused by contact with a metalworking and woodworking machine.

4. Rationale for Excluding Other Options:

Codes 65235 and 65275 in options B, C, and D refer to foreign body removal from the anterior chamber and the anterior segment, respectively, which are not appropriate since the foreign body was located in the posterior segment.

Codes S05.31XA and W31.0XXA in options C and D represent different eye injuries and types of machines, which do not match the scenario described.

5. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, codes should be selected based on the specific location (posterior segment) and the type of foreign body removal. Each procedure, including the corneal repair, should be coded to capture the full extent of the treatment.

Therefore, the correct answer is A. 65265-RT, 66852-51-RT, 65280-51-RT, S05.51XA, W31.1XXA.

Autopsy CPT coding is based on theextent of the examination(gross only vs gross and microscopic) and whether special anatomic components (such asbrain and spinal cord) are included. The question states the pathologist performedboth gross and microscopicexamination and explicitly included thebrain and spinal cord, which indicates acomprehensive autopsyservice rather than a limited or gross-only autopsy. CPT88028represents a complete autopsy with gross and microscopic examination that includes examination of the central nervous system structures (brain and spinal cord) as part of the comprehensive scope. The other codes listed represent different autopsy levels or components that do not match the “gross and microscopic” plus CNS inclusion described. CPC exam approach: anchor first ongross + microscopic(not gross-only), then look for wording that indicates acomplete autopsy. When the stem highlights “brain and spinal cord,” it is signaling the higher-complexity comprehensive autopsy code selection. Therefore,88028is the correct CPT code.
