Official Description

Shortening of tendon, flexor, hand or finger, each tendon

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26479 involves the shortening of a flexor tendon in the hand or finger. This surgical intervention is typically indicated for patients who present with a flexion deformity, which is a condition where the fingers or hand are bent in a way that limits their ability to extend fully. Such deformities can arise from various causes, including the late effects of injuries or chronic conditions such as severe rheumatoid arthritis or osteoarthritis. The goal of this procedure is to correct the deformity by effectively shortening the affected tendon, thereby restoring a more functional position of the hand or finger. The process entails a surgical approach where the tendon is divided, and the ends are overlapped and sutured together to achieve the desired length. This procedure is crucial for improving the range of motion and overall functionality of the hand or finger, allowing patients to regain better use of their extremities. It is important to note that this code is applicable for each tendon that is shortened during the surgical procedure, ensuring accurate coding and billing for the services rendered.

1. Indications

The procedure associated with CPT® Code 26479 is indicated for the following conditions:

  • Flexion Deformity A condition where the fingers or hand are bent, limiting the ability to extend fully.
  • Late Effects of Injuries Deformities that may develop as a result of previous hand or finger injuries.
  • Severe Rheumatoid Arthritis A chronic inflammatory disorder that can lead to joint deformities, including in the fingers and hands.
  • Osteoarthritis A degenerative joint disease that can cause pain and deformity in the hand or fingers.

2. Procedure

The procedure for shortening a flexor tendon, as described by CPT® Code 26479, involves several key steps:

  • Step 1: Incision A skin incision is made over the specific flexor tendon that requires shortening. This incision allows access to the underlying tendon while minimizing damage to surrounding tissues.
  • Step 2: Dissection The soft tissues surrounding the tendon are carefully dissected to expose the tendon fully. This step is crucial to ensure that the tendon can be manipulated without causing unnecessary trauma to adjacent structures.
  • Step 3: Division of the Tendon The flexor tendon is then divided at the appropriate location. This division is essential for the subsequent steps, as it allows for the shortening of the tendon.
  • Step 4: Overlapping and Suturing After the tendon is divided, the ends of the tendon are overlapped and sutured together. This overlapping technique is critical for achieving the desired shortening of the tendon, which will help correct the flexion deformity.
  • Step 5: Immobilization Following the suturing of the tendon, the hand or finger is immobilized in a splint. This immobilization is necessary to maintain the new length of the tendon during the healing process, ensuring that the surgical correction is preserved.

3. Post-Procedure

After the procedure, patients are typically advised to keep the hand or finger immobilized in a splint for a specified period to allow for proper healing of the tendon. The duration of immobilization may vary based on the individual case and the surgeon's recommendations. Patients may also be instructed on post-operative care, including monitoring for signs of infection, managing pain, and gradually beginning rehabilitation exercises as directed by their healthcare provider. Follow-up appointments will be necessary to assess the healing process and to determine when it is appropriate to begin physical therapy to restore function and mobility to the hand or finger.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
