CPC Exam Dumps : Certified Professional Coder (CPC) Exam

The correct answer is A. In the back of the upper leg between the hip and thigh. The hamstrings are a group of muscles located in the posterior thigh, meaning the back portion of the upper leg. Anatomically, the hamstring group includes the biceps femoris, semitendinosus, and semimembranosus muscles. These muscles extend from the pelvis region toward the knee and are primarily responsible for knee flexion and assisting with hip extension. In coding and medical terminology, identifying the correct anatomical location is important because musculoskeletal diagnoses, injuries, repairs, injections, imaging, and rehabilitation services depend on accurate body-region terminology.

The other options describe incorrect anatomical areas. The front of the upper leg is the anterior thigh, mainly associated with the quadriceps muscles. The front of the lower leg refers to the shin or anterior leg compartment. The back of the lower leg is the calf region, which contains muscles such as the gastrocnemius and soleus, not the hamstrings.

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.

This is destruction of malignant lesions (SCC).

17261 = Malignant lesion destruction, trunk/arms/legs, 0.6–1.0 cm

17262 = Same location, 1.1–2.0 cm

Feet are included in trunk/arms/legs.

Therefore, 17262, 17261 is correct.
