CPT® Code 27607

The procedure described by CPT® Code 27607 involves making an incision in the leg or ankle to address 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. During this surgical intervention, the bone cortex of the tibia, fibula, talus, or calcaneus is accessed to treat the underlying infection. The process begins with an incision through the skin and soft tissue that overlays the infected bone area. This incision allows the surgeon to elevate the periosteum, which is the connective tissue that covers the bone, exposing the infected region. A small section, or button, of the cortical bone is then removed to access the bone marrow, which is crucial for relieving pressure caused by inflammation. This step is vital as it helps restore blood flow to the affected area, which is often compromised due to the infection. If pus is present, the surgeon may need to enlarge the initial incision to effectively drain the abscess, ensuring that the infection is adequately addressed. 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 facilitate thorough drainage and treatment of the infection.
