CPT® Code 28140

The procedure described by CPT® Code 28140 refers to a metatarsectomy, which is a surgical operation involving the complete excision of a metatarsal bone. This procedure is typically indicated for various conditions affecting the metatarsal, such as severe deformities, injuries, or infections that compromise the integrity of the bone. During the surgery, a dorsal incision is made over the affected metatarsal, extending to the metatarsophalangeal joint, allowing the surgeon access to the underlying structures. Careful dissection of the soft tissues is performed to protect the digital neurovascular bundle, which is crucial for maintaining sensation and blood supply to the toes. Once the metatarsal bone is fully exposed, it is severed from all its attachments and excised. In cases where the metatarsectomy is performed due to injury or infection, the surgeon will also debride any damaged or septic tissue to promote healing and prevent further complications. After the excision, the soft tissues and skin are meticulously closed in layers, and a drain may be placed to prevent fluid accumulation, followed by the application of a dressing to protect the surgical site.
