CPT® Code 21510

The procedure described by CPT® Code 21510 involves a surgical incision that penetrates deeply into the bone cortex of a bone located in the thoracic region of the body. This intervention is primarily indicated for the treatment of conditions such as osteomyelitis, which is an infection of the bone, or a bone abscess, which is a localized collection of pus within the bone. During the procedure, the surgeon first dissects the skin and underlying tissues to access the bone. Once the bone is exposed, any external abscess present is carefully excised to eliminate the source of infection. The surgeon then drills holes into the bone to facilitate drainage and ensure thorough cleaning of the infected area. The site is irrigated with an antibiotic solution to help combat infection. Following the removal of any necrotic or damaged tissue, the surgical site may be closed with sutures, or it may be packed and left open to allow for continued drainage. If the latter approach is taken, it is essential to change the gauze daily, and a subsequent surgical procedure may be required to close the site once the infection has been adequately managed.
