Official Description

Repair, extensor tendon, finger, 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 fingers can manifest as partial or complete lacerations, tears, or ruptures. These injuries often necessitate surgical intervention to restore function and mobility to the affected finger. The procedure described by CPT® Code 26418 involves the repair of the extensor tendon in the finger, which can be categorized as either a primary or secondary repair. A primary repair is typically performed 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 a surgical intervention that occurs more than two weeks after the initial injury, often due to complications or delayed presentation. The surgical approach for this procedure involves making a dorsal incision to expose the tendon, followed by careful dissection of the surrounding soft tissues while protecting the neurovascular structures. The surgeon locates the distal and proximal ends of the severed tendon, which may require an additional incision if the proximal end has retracted beyond the reach of the initial incision. Once located, the ends of the tendon are approximated and sutured together, effectively restoring the continuity of the tendon. This procedure is reported for each tendon that is repaired, emphasizing the meticulous nature of tendon repair in the context of hand surgery.

1. Indications

Repair of the extensor tendon in the finger 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 the ability to extend the finger, requiring repair to regain normal movement.
  • Rupture - Complete ruptures of the tendon require surgical repair to restore the integrity and function of the extensor mechanism.

2. Procedure

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

  • Dorsal Incision - The surgeon begins by making a dorsal incision over the site of the tendon injury to gain access to the extensor tendon.
  • Dissection of Soft Tissues - Careful dissection of the surrounding soft tissues is performed, ensuring that neurovascular structures are protected throughout the process.
  • 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 it.
  • Approximation and Suturing - Once both ends of the tendon are identified, they are approximated and sutured together to restore continuity. This step is crucial for the functional recovery of the finger.

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 elevated to reduce swelling and to follow specific instructions regarding immobilization of the finger to protect the surgical site. Rehabilitation may include physical therapy to restore movement and strength, and the timeline for recovery can vary based on the extent of the injury and the repair performed. Regular follow-up appointments are necessary to monitor healing and to ensure that the tendon is functioning properly.

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).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
