CPT® Code 27328

The CPT® Code 27328 refers to the excision of a tumor located in the soft tissue of the thigh or knee area, specifically when the tumor is subfascial, meaning it lies beneath the fascia. The term "soft tissue" encompasses various structures, including subcutaneous fat, connective tissue, fascia, muscles, tendons, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. Tumors in these areas 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 over the tumor, which may require the creation and elevation of a skin flap depending on the tumor's location. Once the overlying tissue is dissected, the soft tissue mass is exposed, allowing for the excision of the tumor along with a margin of healthy tissue to ensure complete removal. In some cases, a frozen section may be performed to verify that the 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, a different code, CPT® 27327, is used for excisions of tumors less than 3 cm, while CPT® 27328 is specifically designated for tumors that are less than 5 cm and located below the fascia, including those within muscle tissue.
