CPT® Code 27886

Re-amputation of the leg through the tibia and fibula, as described by CPT® Code 27886, refers to a surgical procedure where a previously amputated leg is re-amputated at a higher level. This procedure is typically performed to remove diseased, infected, or nonviable tissue that poses a risk to the patient's health. Additionally, re-amputation may be necessary to create a healthy stump that can accommodate a prosthesis. The procedure involves careful planning and execution, beginning with the marking of incision lines on the skin to ensure precision. The surgical team incises the skin and underlying soft tissue, exposing the muscles, which are then isolated and divided by muscle group. During this process, nerves and blood vessels are meticulously identified and isolated to prevent any damage, particularly ensuring that nerves are separated from arteries to avoid pulsatile irritation. The nerves are transected and allowed to retract into the surrounding soft tissue, while blood vessels are ligated and transected to control bleeding. The tibia and fibula bones are then exposed, and periosteal flaps are created to facilitate the transection of these bones at the designated level. After the bones are cut, the periosteal flaps are sutured over the remaining bone ends, and antagonistic muscle groups are sutured together and anchored to the periosteum, ensuring that the remaining tibia and fibula are completely enveloped in muscle. Finally, skin flaps are fashioned and sutured over the muscle to complete the procedure, promoting optimal healing and preparing the site for potential prosthetic fitting.
