CPT® Code 28002

The procedure described by CPT® Code 28002 involves an incision and drainage operation performed below the fascia of the foot, specifically targeting a single bursal space. A bursa is a small fluid-filled sac that acts as a cushion between bones and soft tissues, reducing friction and allowing for smooth movement. In cases where a bursa becomes infected, it can lead to significant pain and swelling, necessitating surgical intervention. During this procedure, the surgeon makes an incision in the skin directly over the infected bursa, allowing access to the underlying tissues. The soft tissues are carefully dissected to expose the fascia, which is then incised to reach the infected area. The tendon sheath, which surrounds the tendons in the foot, is also inspected to assess any involvement in the infection. The infected bursal space is opened using a scalpel, and the contents are drained to alleviate pressure and remove pus or other infectious materials. Following drainage, the area is typically flushed with saline or an antibiotic solution to help clear any remaining infection. Depending on the extent of the procedure and the surgeon's assessment, drains may be placed to facilitate further drainage if necessary. The incision may be closed in layers to promote healing or packed with gauze and left open to allow for continued drainage and healing. This procedure is specifically coded as 28002 for cases involving a single bursal space, while 28003 is used for incision and drainage of multiple areas in the foot.
