CPT® Code 22015

The procedure described by CPT® Code 22015 involves the incision and drainage of a deep abscess located in the posterior spine, specifically in the lumbar, sacral, or lumbosacral regions. An abscess is a localized collection of pus that can occur due to infection, and in this case, it is situated beneath the fascia, which is a layer of connective tissue that surrounds muscles and organs. The process begins with making an incision in the skin over the site of the abscess, allowing access to the underlying tissues. The incision is extended through the soft tissue and fascia to reach the abscess pocket. Once accessed, the abscess is opened, and any loculations—small compartments within the abscess—are disrupted using blunt finger dissection. This technique helps to ensure that the entire cavity is adequately drained. Following this, the abscess cavity is typically irrigated with saline or an antibiotic solution to cleanse the area and reduce the risk of further infection. Depending on the size and nature of the abscess, drains may be placed to facilitate ongoing drainage. After the procedure, the incision may be closed in layers to promote healing or packed with gauze and left open to allow for continued drainage and monitoring. It is important to differentiate this procedure from similar ones performed in other spinal regions, such as the cervical or thoracic spine, which are coded differently (CPT® Code 22010).
