Integumentary or musculoskeletal excision
A patient presented for wide excision of melanoma located on the back. The lesion, 4 x 3 cm on the right lateral back, was marked identifying 1 cm margins. The skin incision was made and dissection was taken down through subcutaneous fat to muscular fascia, which served as the deep border. The specimen was excised and the wound was primarily closed. Since melanoma is of cutaneous origin, is the excision of a melanoma always reported with an integumentary excision code, or if a melanoma extends down into a deeper layer such as the fascia/muscle, is it reported with a musculoskeletal excision code? ...

Article Overview
This coding article addresses a melanoma excision scenario involving the back and discusses procedure code selection for lesions documented as extending to a deeper tissue plane. It is intended for coders and billers who need to understand how the provider’s documentation, anatomic location, and excision extent affect code assignment in excision coding guidance.
Why This Topic Matters
Accurate code selection for skin lesion excision depends on documented anatomic depth, lesion size, and location. This article helps readers understand the scope of guidance applied to a melanoma excision case and why body-site and extent of excision documentation matter.
