CPT® Code 28005

The procedure described by CPT® Code 28005 involves an incision into the bone cortex of the foot, specifically targeting conditions such as osteomyelitis or a bone abscess. Osteomyelitis refers to an infection of the bone, while a bone abscess is a localized collection of pus within the bone. The bones of the foot include various structures such as the tarsals, metatarsals, and the proximal, middle, and distal phalanges. During this surgical intervention, an incision is made through the skin and soft tissue to access the infected area of the bone. The periosteum, which is the dense layer of vascular connective tissue enveloping the bones, is carefully elevated to expose the underlying cortical bone. A small section, or button, of the cortical bone is then removed to access the bone marrow, which is crucial for alleviating pressure caused by inflammation and preventing further restriction of blood flow to the affected area. If pus is present, the initial incision may be enlarged using specialized instruments such as a chisel or gouge, allowing for better drainage and treatment of the infection. In cases where the epiphysis, the end part of a long bone, is involved, a portion of the epiphyseal cortex may also be excised to ensure complete drainage of the abscess. This procedure is essential for managing severe bone infections and facilitating recovery by addressing the underlying issues within the bone structure.
