Official Description

Repair, tendon sheath, extensor, forearm and/or wrist, with free graft (includes obtaining graft) (eg, for extensor carpi ulnaris subluxation)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25275 involves the surgical repair of a tendon sheath, specifically the extensor tendon sheath located in the forearm and/or wrist. This procedure is performed using a free graft, which includes the process of obtaining the graft material necessary for the repair. A common indication for this type of repair is a tear or laceration of the extensor tendon sheath, which can occur without any injury to the extensor tendon itself. One frequent site of such injuries is the extensor carpi ulnaris (ECU) tendon sheath at the wrist. This injury often results from a partial dislocation of the wrist, known as subluxation, which can be caused by movements such as forced supination, palmar flexion, or ulnar deviation. The ECU tendon is situated in the sixth dorsal compartment of the wrist, making it susceptible to these types of injuries. The surgical procedure involves making an incision over the dorsal aspect of the wrist and the distal ulna, carefully dissecting the soft tissues while protecting the dorsal branch of the ulnar nerve. The retinaculum of the sixth dorsal compartment is then exposed, allowing for inspection and subsequent repair of the damaged tendon sheath using a graft harvested from the dorsal retinaculum of the wrist.

1. Indications

The procedure is indicated for the following conditions:

  • Tear or laceration of the extensor tendon sheath - This condition occurs when there is damage to the protective sheath surrounding the extensor tendon, which can lead to pain and dysfunction in wrist movement.
  • Extensor carpi ulnaris subluxation - This is a specific type of injury where the ECU tendon experiences partial dislocation, often due to forced movements such as supination, palmar flexion, or ulnar deviation.

2. Procedure

The surgical procedure for repairing the extensor tendon sheath involves several critical steps:

  • Step 1: Incision - An incision is made over the dorsal aspect of the wrist and the distal ulna to access the affected area. This incision allows the surgeon to visualize the underlying structures and proceed with the repair.
  • Step 2: Dissection - The soft tissues are carefully dissected to expose the retinaculum of the sixth dorsal compartment. During this step, special care is taken to protect the dorsal branch of the ulnar nerve to prevent any nerve damage during the procedure.
  • Step 3: Exposure and Inspection - Once the retinaculum is exposed, it is incised to allow for further access to the tendon sheath. The surgeon inspects the tendon sheath to locate the tear or laceration.
  • Step 4: Examination of the Tendon - The tendon sheath is incised, and the extensor tendon is examined to confirm that it remains intact, ensuring that the repair focuses solely on the sheath.
  • Step 5: Debridement - Any damaged tissue within the retinaculum and tendon sheath is debrided to prepare the area for grafting and to promote healing.
  • Step 6: Graft Harvesting - A graft is harvested from the dorsal retinaculum of the wrist. This graft will be used to repair the damaged tendon sheath.
  • Step 7: Repair - The harvested retinacular graft is then utilized to repair both the tendon sheath and the retinaculum of the sixth dorsal compartment, restoring the integrity of the structures involved.

3. Post-Procedure

Post-procedure care typically involves monitoring the surgical site for signs of infection and ensuring proper healing of the graft. Patients may be advised to limit movement of the wrist to facilitate recovery and may require physical therapy to regain strength and mobility in the wrist following the healing period. The specific recovery timeline and rehabilitation protocol will depend on the individual patient's condition and the extent of the surgical repair.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
