CPT® Code 26113

The CPT® Code 26113 refers to the excision of a tumor or vascular malformation located in the soft tissue of the hand or finger, specifically when the procedure is performed subfascially, meaning beneath the fascia, which is a layer of connective tissue. The size of the tumor or malformation must be 1.5 cm or greater for this code to be applicable. 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 found 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 surgical approach may involve incising the skin directly over the tumor or creating and elevating a skin flap 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 frozen section may be performed to verify 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 excisions of tumors or vascular malformations that are less than 1.5 cm in size, different codes are used, such as CPT® Code 26115 for subcutaneous fat or connective tissue and CPT® Code 26116 for those lying below the fascia.
