CPT® Code 21013

The CPT® Code 21013 refers to the excision of a tumor located in the soft tissue of the face and scalp, specifically when the tumor is situated subfascially, which includes areas such as subgaleal or intramuscular locations. The term "soft tissue" encompasses various 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 procedure involves careful planning based on the tumor's location within the soft tissue of the face or scalp. The surgeon may make an incision over the tumor, create and elevate a skin flap, or utilize a series of incisions along natural skin creases to gain access to the tumor. Once the overlying tissue is dissected, the soft tissue mass is exposed, allowing for the excision of the tumor 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, which is crucial for ensuring that the tumor has been completely excised. After the tumor removal, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For tumors located in the subcutaneous fat or connective tissue, different CPT codes are used based on the size of the mass, while CPT 21013 is specifically designated for subfascial tumors that are less than 2 cm in size.
