Tenodesis at wrist; flexors of fingers

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Tenodesis at the wrist, specifically for the flexors of the fingers, is a surgical procedure aimed at addressing injuries to the tendon, such as tears or ruptures. This procedure involves a series of meticulous steps to ensure the proper repair and reattachment of the tendon to restore functionality. The process begins with the identification and inspection of the affected tendon, which may require detachment from its insertion site to facilitate thorough examination and treatment. During the procedure, any damaged or degenerated tendon tissue is carefully excised to promote healing and restore the integrity of the tendon. If there are any longitudinal tears present, these are repaired to ensure the tendon can function effectively post-surgery. Once the tendon is adequately prepared, it is reattached to the appropriate bone at the wrist using sutures or bone anchors, which provide stability and support for the healing process. Following the surgical intervention, the joint is typically flushed with sterile saline to reduce the risk of infection, and the incisions are closed securely. A dressing is then applied to protect the surgical site. For coding purposes, the CPT® code 25300 is designated for the tenodesis of the flexors of the fingers, while 25301 is used for the tenodesis of the extensors of the fingers.

1. Indications

The tenodesis procedure at the wrist for the flexors of the fingers is indicated for specific conditions that affect the integrity and function of the tendon. These indications include:

  • Tendon Tear or Rupture - This procedure is performed when there is a complete or partial tear of the flexor tendon, which may result from trauma or overuse.
  • Degenerative Tendon Conditions - Conditions that lead to the degeneration of the tendon tissue may necessitate a tenodesis to restore function and alleviate pain.
  • Loss of Finger Function - Patients experiencing significant loss of function in their fingers due to tendon injuries may require this surgical intervention to regain mobility and strength.

2. Procedure

The tenodesis procedure for the flexors of the fingers involves several critical steps to ensure successful tendon repair and reattachment. The steps include:

  • Step 1: Identification and Inspection - The surgeon begins by locating the affected tendon in the wrist area. This involves careful dissection to expose the tendon while minimizing damage to surrounding tissues.
  • Step 2: Detachment from Insertion Site - If necessary, the tendon is detached from its insertion site to allow for thorough inspection and treatment of any damage present along its length.
  • Step 3: Debridement and Tissue Excising - The surgeon debrides the tendon, removing any damaged or necrotic tissue to promote healing. This step is crucial for ensuring that only healthy tendon tissue remains for reattachment.
  • Step 4: Repair of Longitudinal Tears - Any longitudinal tears in the tendon are meticulously repaired to restore the tendon’s structural integrity, which is essential for its function.
  • Step 5: Reattachment to Bone - The prepared tendon is then reattached to the appropriate bone at the wrist using sutures or bone anchors, providing a secure connection that will support healing.
  • Step 6: Joint Flushing and Closure - After the tendon is secured, the joint is flushed with sterile saline to reduce the risk of infection. The incisions made during the procedure are then closed, and a dressing is applied to protect the surgical site.

3. Post-Procedure

Post-procedure care following a tenodesis at the wrist involves monitoring the surgical site for signs of infection and ensuring proper healing of the tendon. Patients are typically advised to follow specific rehabilitation protocols, which may include physical therapy to restore range of motion and strength in the fingers. Pain management strategies may also be implemented to address discomfort during the recovery phase. It is essential for patients to adhere to follow-up appointments to assess the healing process and make any necessary adjustments to their rehabilitation plan.

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.
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.
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.
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).
