CPC Exam Dumps : Certified Professional Coder (CPC) Exam

For Mohs micrographic surgery, CPT® coding is based on the anatomic location of the lesion, the number of stages, and the number of tissue blocks per stage.

17311: This code is used for Mohs surgery on body areas such as the trunk, arms, or legs for the first stage.

17315: This is an add-on code used when more than five tissue blocks are examined in a single stage. Since this case involved six tissue blocks, 17315 is appropriate.

Explanation of incorrect answers:

A. 17313, 17314, 17315: Incorrect, as 17313 applies to the head, neck, hands, feet, or genitalia, not the arm.

C. 17313, 17315: Incorrect, as 17313 is not appropriate for the arm.

D. 17311, 17312, 17315: 17312 is used for additional stages beyond the first, which is not applicable here since only one stage was performed.

E. 85B2-335 is not a valid CPT code for Mohs surgery.

Thus, the correct answer is B. 17311, 17315, which accurately reflects a single-stage Mohs surgery with six tissue blocks on the arm.

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.

The urinalysis performed is described asautomated, without microscopy, which corresponds to CPT81003(urinalysis, automated, without microscopy). CPT81001includes microscopy and is not supported because the question explicitly states “without microscopy.” For diagnosis coding, the providersuspecteda UTI, but the urinalysis is negative andUTI is ruled outas the final diagnosis. Under ICD-10-CM reporting principles, conditions documented asruled outarenot codedin the outpatient/office setting; instead, you code thesigns and symptomsthat prompted the visit and testing. The symptoms documented aredysuriaandlower abdominal pain, which are coded asR30.0andR10.30(as presented in the answer choices). Therefore, the correct combination is81003withR30.0andR10.30only. CPC exam tip: outpatient “rule out” → codesymptoms, not the excluded diagnosis.
