Official Description

Tenodesis at wrist; extensors of fingers

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Tenodesis at the wrist, specifically for the extensors of the fingers, is a surgical procedure aimed at addressing issues related to tendon injuries. This procedure is typically indicated for patients who have experienced a tear or rupture of the tendon, which can significantly impair hand function. During the tenodesis, the surgeon locates and inspects the affected tendon, which is crucial for understanding the extent of the injury. The tendon may need to be detached from its insertion site to allow for proper repair. Following this, the surgeon performs debridement, which involves the removal of damaged tendon tissue to promote healing and restore function. If there are any tears along the length of the tendon, these are meticulously repaired to ensure the integrity of the tendon is restored. Once the tendon is adequately prepared, it is reattached to the appropriate bone at the wrist using sutures or bone anchors, which secure the tendon in place. After the surgical intervention, the joint is flushed with sterile saline to reduce the risk of infection, and the incisions are closed with sutures. A dressing is then applied to protect the surgical site during the initial healing phase. It is important to note that CPT® Code 25301 is specifically designated for the tenodesis of the extensors of the fingers, distinguishing it from similar procedures involving the flexors, which are coded under 25300.

1. Indications

Tenodesis at the wrist for the extensors of the fingers is performed under specific clinical circumstances. The primary indications for this procedure include:

  • Tendon Tear or Rupture - This procedure is indicated for patients who have sustained a tear or rupture of the extensor tendon, which can lead to loss of function in the fingers.
  • Severe Tendon Damage - Patients with significant damage to the tendon that cannot be repaired through less invasive methods may require tenodesis to restore functionality.
  • Chronic Tendon Dysfunction - Individuals experiencing chronic issues with tendon function, such as weakness or inability to extend the fingers, may benefit from this surgical intervention.

2. Procedure

The procedure for tenodesis at the wrist for the extensors of the fingers involves several critical steps, each designed to ensure the successful repair and restoration of tendon function. The steps include:

  • Step 1: Identification and Inspection - The surgeon begins by locating the affected extensor tendon. This involves a thorough inspection to assess the extent of the injury and determine the best approach for repair.
  • Step 2: Detachment of the Tendon - If necessary, the tendon is detached from its insertion site. This step is crucial for allowing access to the damaged areas of the tendon that require repair.
  • Step 3: Debridement - The surgeon performs debridement, which involves the careful removal of any damaged or necrotic tendon tissue. This step is essential for promoting healing and ensuring that only healthy tissue remains for reattachment.
  • Step 4: Repair of Tears - Any tears along the length of the tendon are meticulously repaired. This may involve suturing the torn edges together to restore the continuity of the tendon.
  • Step 5: Reattachment - The prepared tendon is then reattached to the appropriate bone at the wrist. This is typically done using sutures or bone anchors, which provide a secure fixation to allow for proper healing and function.
  • Step 6: Joint Flushing - After the tendon has been reattached, the joint is flushed with sterile saline. This step helps to reduce the risk of infection and ensures that the surgical site is clean.
  • Step 7: Closure of Incisions - The incisions made during the procedure are then closed with sutures. Proper closure is vital for minimizing scarring and promoting healing.
  • Step 8: Application of Dressing - Finally, a dressing is applied to the surgical site to protect it during the initial recovery phase and to support the healing process.

3. Post-Procedure

After the tenodesis procedure, patients can expect a recovery period that may involve specific post-operative care. This typically includes monitoring for any signs of infection at the surgical site, managing pain with prescribed medications, and following up with physical therapy to regain strength and mobility in the fingers. The duration of recovery can vary based on the individual’s overall health and adherence to rehabilitation protocols. It is essential for patients to follow their surgeon's instructions regarding activity restrictions and rehabilitation exercises to ensure optimal healing and restoration of function.

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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
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.
