CPT® Code 26483

Transfer or transplant of tendon, carpometacarpal area or dorsum of hand; with free tendon graft (includes obtaining graft), each tendon

The procedure described by CPT® Code 26483 involves the transfer or transplantation of a tendon specifically in the carpometacarpal area or the dorsum of the hand. This surgical intervention is typically performed to restore functionality that may have been compromised due to traumatic injuries affecting the nerve, tendon, or muscle. In some cases, the loss of function may also arise from conditions such as rheumatoid arthritis or gouty arthritis. The primary goal of this procedure is to re-establish the normal movement and strength of the hand by relocating a tendon from one area to another. The process begins with a longitudinal incision over the donor tendon, allowing the surgeon to expose and free the tendon from its attachments. This careful dissection is crucial to ensure that the tendon can be securely attached to the recipient site. The procedure may also involve harvesting the tendon along with a strip of periosteum to enhance the graft's stability. Additionally, muscle may be released from its fascial attachments to provide the donor tendon with maximum mobility and length necessary for effective transfer. A second incision is made at the recipient site, where the donor tendon will be anchored. The tendon is then routed to this site and temporarily secured with sutures. To ensure proper function, a neuromuscular stimulator is employed to test the donor tendon, allowing for adjustments in tension as needed before finalizing the attachment. After the surgical wounds are closed, immobilization of the wrist and/or hand is implemented to facilitate healing. It is important to note that CPT® Code 26483 is specifically used when a tendon graft is required to achieve the desired length, while CPT® Code 26480 is applicable for tendon transfers that do not involve grafting.
