CPT® Code 25909

The procedure described by CPT® Code 25909 refers to the re-amputation of the forearm through the radius and ulna. This surgical intervention is performed when there is a need to remove diseased, infected, or nonviable tissue that poses a risk to the patient's health. The re-amputation is typically conducted at a higher level than a previous amputation to ensure that a healthy stump is created, which can be utilized for fitting a prosthesis. The process begins with careful planning, where incision lines are marked on the skin to guide the surgical approach. The surgery involves incising the skin and underlying soft tissue, followed by the exposure and isolation of muscle groups. During the procedure, special attention is given to the identification and separation of nerves and blood vessels to prevent any potential complications, such as nerve irritation from pulsatile blood flow. The bones, specifically the radius and ulna, are then exposed, and periosteal flaps are created to facilitate the transection of the bones at the appropriate level. After the bones are cut, the periosteal flaps are sutured over the remaining bone segments to promote healing. Additionally, the antagonistic muscle groups are sutured together and anchored to the periosteum, ensuring that the remaining bone is completely enveloped in muscle tissue. Finally, skin flaps are fashioned and sutured over the muscle to complete the procedure, providing a well-structured and functional stump for potential prosthetic use.
