What is the appropriate code for an adjacent tissue transfer of a skin defect of the chin resulting from the excision of a benign skin lesion?

The correct code for an adjacent tissue transfer of a skin defect of the chin resulting from the excision of a benign skin lesion is 14040. This code specifically refers to the procedure of moving local tissue to repair a defect in the skin, highlighting its use for areas like the face, scalp, neck, and ears, which includes the chin.

In coding, adjacent tissue transfer procedures are typically categorized based on the area being repaired and the complexity involved. The chin is considered part of the face, and since the procedure involves transferring surrounding healthy tissue to close a defect created by the excision, 14040 accurately captures that specific scenario.

Other code options do not align with the procedure described; for instance, the codes related to excisions or lesions do not apply here since the main procedure is the reconstruction of the tissue using adjacent skin rather than the excision of the lesion itself. Thus, 14040 stands out as the most appropriate choice for this surgical procedure involving tissue transfer on the chin area.
