CPT® Code 28039

The procedure described by CPT® Code 28039 involves the excision of a tumor located in the soft tissue of the foot or toe, specifically when the tumor measures 1.5 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 surgical approach 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 excision, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For smaller tumors measuring less than 1.5 cm, different CPT codes are utilized, such as CPT® Code 28043 for excision of subcutaneous tumors and CPT® Code 28045 for tumors located below the fascia.
