CPT® Code 21502

The CPT® Code 21502 refers to a surgical procedure involving the incision and drainage of a deep abscess or hematoma located in the soft tissues of the neck or thorax, accompanied by a partial rib ostectomy. This procedure is typically indicated when there is a significant accumulation of pus or blood that requires intervention to prevent further complications. The physician initiates the process by making an incision in the skin directly over the site of the abscess or hematoma. This incision allows access to the underlying soft tissues, where the abscess or hematoma is located. The physician then carefully opens the abscess or hematoma to facilitate drainage. In cases of an abscess, any loculated areas are meticulously broken up using blunt finger dissection to ensure complete drainage. For hematomas, the physician employs suction to remove any clotted blood. Following the drainage, the cavity is thoroughly flushed with saline or an antibiotic solution to reduce the risk of infection. Depending on the situation, drains may be placed to allow for continued drainage of any residual fluid. The incision may be closed in layers or packed with gauze and left open to promote healing. In instances where the abscess involves the bone, a partial rib ostectomy is performed. This involves the excision of a portion of the rib to address any bony involvement or to manage a fistulous tract that may be present. The rib is carefully inspected for signs of destruction or granulation tissue, and any affected areas are resected to ensure complete resolution of the infection or hematoma.
