CPT® Code 21932

The CPT® Code 21932 refers to the excision of a tumor located in the soft tissue of the back or flank, specifically when the tumor is subfascial, meaning it is situated beneath the fascia, which is a layer of connective tissue. This procedure is applicable for tumors that measure less than 5 centimeters 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 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 surgical process begins with making an incision over the tumor site on the back or flank, or alternatively, creating and elevating a skin flap. The surgeon then dissects the overlying tissue to expose the soft tissue mass. The tumor is 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 excision, drains may be placed as necessary, and the surgical wound is closed in layers. It is important to note that for tumors located in the subcutaneous fat or connective tissue, different codes are used based on the size of the mass, with CPT® Code 21930 designated for masses less than 3 cm and CPT® Code 21931 for those 3 cm or greater. For subfascial tumors, CPT® Code 21932 is specifically used for masses less than 5 cm, while CPT® Code 21933 is reserved for those measuring 5.0 cm or greater. Subfascial soft tissue tumors include those that are found within muscle tissue.
