CPC Exam Dumps : Certified Professional Coder (CPC) Exam

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).

Procedure Coding (CPT®):

31287 – Nasal/sinus endoscopy, surgical; with sphenoidotomy

Correct because the surgeon performed a surgical endoscopic sphenoidotomy to evaluate and treat sphenoid sinus injury.

No CSF leak repair was performed, so codes 31290–31291 are not appropriate.

31231-59 – Nasal endoscopy, diagnostic

Diagnostic endoscopy is separately reportable because:

It was performed to evaluate traumatic injury

It is not bundled into the surgical service when it provides distinct diagnostic information

Modifier -59 indicates a separate and distinct service per NCCI edits.

Diagnosis Coding (ICD-10-CM):

S02.109A – Unspecified fracture of base of skull, initial encounter for closed fracture

The anterior cranial fossa fracture with sphenoid sinus involvement qualifies as a skull base fracture

No CSF leak is documented

Correct 7th character “A” for initial encounter

Why Other Options Are Incorrect:

A – Incorrect format and duplicated CPT logic

B – 31267 = maxillary sinus, wrong sinus

D – 31291 includes CSF leak repair, which was not performed

Warthin ' s tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor of the salivary glands, most commonly affecting the parotid gland. It typically presents as a painless, slow-growing mass near the angle of the jaw.
