What Constitutes the Trunk for Complex Repairs?

Question:

CPT question for anatomy: When coding complex repairs CPT 13100-13102 for complex repair of trunk. What body area is included in the “Trunk”.  For simple and intermediate repairs the trunk is included with the scalp, extremities, neck, axillae and trunk.

Answer:

You can determine the answer by looking at the code descriptors for the other complex repair anatomic groupings. CPT codes 1312-13122 include the scalp, arms, and/or legs; CPT codes 13131-13133 include the forehead, cheeks, chin, mouth, neck, axillae, genitalia, hands and/or feet. Therefore, 13100-13102 is specifically just the trunk – chest, abdomen, and back.
