Official Description

Reconstruction of tendon pulley, each tendon; with tendon or fascial graft (includes obtaining graft) (separate procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26502 involves the reconstruction of a tendon pulley, specifically utilizing a tendon or fascial graft. This procedure is categorized as a separate procedure, which means it is performed independently and is not part of a more comprehensive surgical intervention. The tendon pulley system is essential for the proper flexion of the fingers, consisting of a series of annular and cruciate pulleys that facilitate the movement of tendons. In the fingers, the second annular (A2) and fourth annular (A4) pulleys are particularly crucial, while the thumb relies on the oblique pulley for its flexion capabilities. When a critical pulley sustains an injury, the ability to flex the finger is significantly impaired unless surgical reconstruction is performed. The reconstruction process may involve the use of local tissue, such as the flexor digitorum superficialis (FDS), or a graft harvested from another site, typically the forearm or leg. The procedure entails exposing the damaged pulley, excising any compromised tissue, and securing the graft to reconstruct the pulley structure. This meticulous approach ensures that the pulley is restored to its functional state, allowing for improved range of motion and finger dexterity post-surgery.

1. Indications

The reconstruction of tendon pulleys using CPT® Code 26502 is indicated for patients who have sustained injuries to critical pulleys that compromise finger flexion. The specific indications for this procedure include:

  • Injury to Critical Pulleys Damage to the second annular (A2) or fourth annular (A4) pulleys in the fingers, or the oblique pulley in the thumb, which are essential for normal flexion.
  • Flexion Compromise Inability to flex the affected finger or thumb due to the injury of the pulley system.
  • Need for Reconstruction Requirement for surgical intervention to restore the integrity and function of the pulley system through reconstruction with tendon or fascial grafts.

2. Procedure

The procedure for reconstructing a tendon pulley as described by CPT® Code 26502 involves several critical steps:

  • Step 1: Graft Harvesting A tendon or fascial graft is harvested from a donor site, typically the forearm or leg. This graft will be used to reconstruct the damaged pulley.
  • Step 2: Exposure of the Pulley The surgical site is prepared, and the injured pulley is exposed. This may involve making an incision to access the affected area and carefully dissecting surrounding tissues to visualize the pulley.
  • Step 3: Tissue Excision Any damaged or necrotic tissue associated with the injured pulley is excised to ensure a healthy base for the reconstruction.
  • Step 4: Graft Securing The harvested tendon or fascial graft is then secured to the remnant of the pulley. This may involve passing the graft through drill holes in the bone or wrapping it around the phalanx to create a new functional pulley.
  • Step 5: Tension Adjustment After securing the graft, the range of motion is checked, and the tension is adjusted to achieve the desired snugness of the pulley, ensuring optimal function.
  • Step 6: Wound Closure The operative wound is closed in layers to promote healing, and the hand is placed in a bulky dressing and splint to immobilize the area during the initial recovery phase.

3. Post-Procedure

Post-procedure care following the reconstruction of tendon pulleys involves monitoring the surgical site for signs of infection and ensuring proper healing. Patients are typically advised to keep the hand elevated and immobilized in a splint to minimize swelling and promote recovery. Physical therapy may be recommended to restore range of motion and strength in the affected finger or thumb as healing progresses. Follow-up appointments are essential to assess the success of the reconstruction and make any necessary adjustments to the rehabilitation plan.

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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.)
