CPT® Code 28805

The CPT® Code 28805 refers to a surgical procedure known as a transmetatarsal amputation, which involves the removal of the foot at the level of the metatarsal bones. This type of amputation is typically indicated for patients suffering from severe conditions such as infection, ischemia, or trauma that compromise the integrity of the foot. The procedure is characterized by the creation of both dorsal and plantar flaps, which are essential for ensuring adequate coverage of the remaining bone and soft tissue after the amputation. During the operation, the surgeon carefully incises the skin and elevates the flexor and extensor muscles to create a musculofascial flap. This meticulous dissection allows for the ligation and division of blood vessels and digital nerves at a more proximal level, which is crucial for minimizing postoperative complications. The metatarsals are then transected, and the remaining bone surfaces are smoothed to eliminate any bony prominences that could lead to discomfort or complications. Finally, the osteoperiosteal flaps are sutured over the exposed diaphyses of the metatarsals, and the muscle groups are sutured together to promote healing. The procedure concludes with the closure of the dorsal and plantar soft tissue flaps and the application of a bulky dressing to support the surgical site during the recovery process.
