CPT® Code 22902

The CPT® Code 22902 refers to the excision of a tumor located in the soft tissue of the abdominal wall, specifically within the subcutaneous layer, when the tumor measures less than 3 cm. 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 procedure involves making an incision in the skin over the tumor or creating and elevating a skin flap to gain access to the tumor. Once exposed, the overlying tissue is carefully dissected to reveal 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 closed in layers. For coding purposes, it is important to note that for tumors located in the subcutaneous fat or connective tissue, CPT® Code 22902 is applicable for masses less than 3 cm, while CPT® Code 22903 is used for masses measuring 3 cm or greater. Additionally, for tumors situated below the fascia, CPT® Code 22900 is designated for masses less than 5 cm, and CPT® Code 22901 is for those 5 cm or greater. Subfascial soft tissue tumors include those found within muscle tissue.
