CPT® Code 27337

The procedure described by CPT® Code 27337 involves the excision of a tumor located in the soft tissue of the thigh or knee area, specifically when the tumor measures 3 cm or greater. 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 within 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 separately reportable 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 removed. After the excision, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. It is important to note that for tumors located in the subcutaneous fat or connective tissue, CPT® Code 27337 is applicable, while tumors situated below the fascia, such as those within muscle tissue, would require the use of CPT® Code 27339 for excision of soft tissue measuring 5 cm or greater.
