Official Description

Repair or advancement of profundus tendon, with intact superficialis tendon; secondary with free graft (includes obtaining graft), each tendon

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26372 involves the repair or advancement of the flexor digitorum profundus (FDP) tendon when the flexor digitorum superficialis (FDS) tendon remains intact. The FDP tendon is crucial for finger flexion, extending from the upper anterior and medial aspects of the ulna to the wrist, where it divides into four tendons that insert at the palmar base of the distal phalanx of each finger. In cases where the FDP tendon has been injured, a secondary repair is indicated, particularly when the repair is performed more than two weeks after the initial injury. This procedure utilizes a free graft, which is a segment of tendon harvested from another site, typically the palmaris longus tendon from the distal forearm. The graft is essential for reconstructing the damaged tendon, allowing for proper function and healing. The surgical approach involves exposing the site of the original tendon injury, locating the severed ends of the FDP, and attaching the graft to the affected portion of the tendon, which is then tunneled to the base of the distal phalanx for secure anchoring. This method is critical for restoring the integrity and functionality of the tendon, ensuring that the patient can regain finger movement and strength following the repair.

1. Indications

The procedure described by CPT® Code 26372 is indicated for the following conditions:

  • Secondary Repair of FDP Tendon Injury This procedure is performed when there is a need to repair the flexor digitorum profundus tendon more than two weeks after the initial injury, particularly when the flexor digitorum superficialis tendon remains intact.
  • Severe Tendon Damage It is indicated in cases where the FDP tendon has been significantly damaged and requires reconstruction using a free graft to restore function.
  • Inability to Perform Primary Repair This procedure is necessary when a primary repair is not feasible due to the timing of the injury or the condition of the tendon ends.

2. Procedure

The procedure for CPT® Code 26372 involves several critical steps to ensure successful repair of the FDP tendon using a free graft:

  • Exposure of the Injury Site The surgeon begins by making a volar zigzag or lateral incision to expose the site of the original tendon injury. Care is taken to dissect the soft tissues while protecting the surrounding neurovascular structures.
  • Identification of Tendon Ends The distal and proximal ends of the severed FDP tendon are located. If the proximal end has retracted and is not accessible through the initial incision, a separate incision may be necessary to locate it.
  • Harvesting the Graft A tendon graft, typically the palmaris longus tendon from the distal forearm, is harvested. This graft will be used to reconstruct the damaged portion of the FDP tendon.
  • Attachment of the Graft The harvested graft is then attached to the affected portion of the FDP tendon. The graft is tunneled to the base of the distal phalanx, where it is securely anchored to the phalangeal base to restore continuity and function.

3. Post-Procedure

After the procedure, the patient will typically require a period of immobilization to allow for proper healing of the tendon repair. Rehabilitation may include physical therapy to regain strength and range of motion in the affected finger. The surgeon will provide specific post-operative care instructions, including wound care and signs of potential complications, such as infection or graft failure. Follow-up appointments will be necessary to monitor the healing process and assess the functional recovery of the tendon.

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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
