CPT® Code 24305

Tendon lengthening is a surgical procedure aimed at correcting flexion or extension contractures in the upper arm or elbow. This condition occurs when the tendons become shortened, limiting the range of motion in the affected joint. The procedure involves making a skin incision over the elbow or upper arm to access the tendon of the muscle that is causing the contracture. A common technique used during this procedure is the Z-plasty incision, which allows for effective lengthening of the tendon. Once the tendon is identified, it is incised, and the surgeon checks the range of motion to ensure that the desired lengthening has been achieved. After the tendon has been appropriately lengthened, the overlying soft tissues and skin are meticulously closed in layers to promote proper healing. To maintain the new length of the tendon and support the joint during the recovery process, a cast or splint is applied. It is important to note that this CPT® code is reported separately for each tendon that is incised and lengthened, reflecting the specific nature of the surgical intervention performed.
