Official Description

Repair, extensor tendon, hand, primary or secondary; without free graft, each tendon

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Injuries to the extensor tendons of the hand can manifest as partial or complete lacerations, tears, or ruptures. These injuries often necessitate surgical intervention to restore function and integrity to the tendon. The procedure described by CPT® Code 26410 involves the repair of the extensor tendon in the hand, which can be categorized as either a primary or secondary repair. A primary repair is typically conducted within 24 hours following the injury, allowing for optimal healing conditions. However, in cases where the wound is grossly contaminated, the primary repair may be postponed for up to two weeks to ensure a cleaner surgical environment. Conversely, a secondary repair is defined as one that is performed more than two weeks after the initial injury, often due to complications or delayed presentation. The surgical approach involves exposing the tendon through a dorsal incision, with careful dissection of the surrounding soft tissues to protect vital neurovascular structures. Once the tendon is accessed, the surgeon locates the distal and proximal ends of the severed tendon, which may require additional incisions if the proximal end has retracted beyond the reach of the initial incision. The procedure culminates in the approximation and suturing of the tendon ends, effectively restoring continuity and function. This code is specifically utilized for each tendon that is repaired without the use of a free graft, distinguishing it from related procedures that may involve grafting techniques.

1. Indications

Repair of the extensor tendon in the hand is indicated for the following conditions:

  • Partial or Complete Laceration - This includes injuries where the tendon is either partially cut or completely severed, necessitating surgical intervention to restore function.
  • Tear - A tear in the extensor tendon can impair hand movement and may require repair to regain full functionality.
  • Rupture - Complete ruptures of the tendon require surgical repair to reconnect the severed ends and restore the ability to extend the fingers.

2. Procedure

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

  • Step 1: Incision - A dorsal incision is made over the site of the tendon injury to provide access to the extensor tendon. This incision allows the surgeon to visualize the tendon and surrounding structures.
  • Step 2: Dissection - The soft tissues surrounding the tendon are carefully dissected. During this step, the surgeon must take special care to protect the neurovascular structures that are adjacent to the tendon to prevent any damage that could lead to complications.
  • Step 3: Identification of Tendon Ends - The distal and proximal ends of the severed 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 and retrieve it.
  • Step 4: Approximation and Suturing - Once both ends of the tendon are identified, they are approximated and sutured together. This step is crucial for restoring the continuity of the tendon and enabling proper function of the hand.

3. Post-Procedure

After the repair of the extensor tendon, post-procedure care is essential for optimal recovery. Patients are typically advised to keep the hand immobilized to allow for proper healing of the tendon. Follow-up appointments are necessary to monitor the healing process and to assess the function of the tendon. Rehabilitation may include physical therapy to restore movement and strength in the hand, depending on the extent of the injury and the repair performed. The recovery timeline can vary based on the severity of the injury and the type of repair conducted, with primary repairs generally having a more favorable prognosis than secondary repairs.

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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
