CPT® Code 27618

The procedure described by CPT® Code 27618 involves the excision of a tumor located in the soft tissue of the leg or ankle area, specifically when the tumor is subcutaneous and measures less than 3 cm in size. 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 approach to excision may vary based on the tumor's location; for instance, the skin over the tumor may be incised directly, or a skin flap may be created and elevated to access the tumor. During the procedure, the overlying tissue is carefully dissected to expose the soft tissue mass, which is then excised 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 a separate reportable procedure. After the tumor is excised, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For excisions of tumors that are located in the subcutaneous fat or connective tissue and are less than 3 cm, CPT® Code 27618 is the appropriate code to use. In contrast, for tumors that are situated below the fascia, CPT® Code 27619 should be utilized for excisions of less than 5 cm, as subfascial soft tissue tumors include those found within muscle tissue.
