CPT® Code 26115

The CPT® Code 26115 refers to the excision of a tumor or vascular malformation located in the soft tissue of the hand or finger, specifically when the size of the excised mass is less than 1.5 cm. Soft tissues encompass a variety of structures, including subcutaneous fat, connective tissue, fascia, muscles, tendons, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. Tumors that arise in these soft tissues can be either benign or malignant. Typically, benign tumors are treated through excision, while small malignant or indeterminate tumors may also be excised if they have well-defined margins. The procedure involves careful consideration of the tumor's location; the skin over the tumor may be incised directly, or a skin flap may be created and elevated to access the underlying tissue. Once the overlying tissue is dissected, the soft tissue mass is exposed, allowing for the excision of the tumor or vascular malformation along with a margin of healthy tissue to ensure complete removal. In some cases, a separately reportable frozen section may be performed during the procedure to confirm that all margins are free of tumor cells. After the excision, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For coding purposes, it is important to distinguish between excisions based on size and depth; for instance, CPT® Code 26115 is specifically used for excisions of less than 1.5 cm in the subcutaneous fat or connective tissue, while other codes apply for larger excisions or those located deeper beneath the fascia.
