Official Description

Tenolysis, extensor, foot; single tendon

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Tenolysis is a surgical procedure aimed at freeing a tendon from the surrounding tissue that may be restricting its movement. Specifically, CPT® Code 28225 refers to the tenolysis of a single extensor tendon located in the foot. This procedure is typically indicated when there is a presence of scar tissue that has formed due to trauma or a disease process, which can impede the normal motion of the foot and toes. The goal of the tenolysis is to restore the range of motion by carefully releasing these adhesions. During the procedure, a surgical incision is made directly over the affected extensor tendon, allowing the surgeon to access the tendon and the surrounding soft tissues. The surgeon then meticulously dissects the soft tissues to identify the affected tendon, after which the adhesions are severed to free the tendon. Following the release, the range of motion of the tendon is evaluated to ensure that the procedure has been successful. Finally, the surgical wound is closed in layers, and a dressing is applied to protect the area as it heals. This procedure is crucial for patients who have experienced limitations in foot and toe movement due to the aforementioned conditions.

1. Indications

Tenolysis, as described by CPT® Code 28225, is indicated for patients experiencing restricted motion of the foot and/or toes due to the formation of scar tissue. This condition may arise from various factors, including:

  • Trauma: Injuries to the foot that result in tendon damage and subsequent scarring.
  • Disease Process: Conditions such as rheumatoid arthritis or other inflammatory diseases that can lead to tendon adhesions.

2. Procedure

The procedure for tenolysis of a single extensor tendon in the foot involves several critical steps, which are outlined as follows:

  • Step 1: An incision is made over the affected extensor tendon. This incision is strategically placed to provide optimal access to the tendon while minimizing damage to surrounding tissues.
  • Step 2: The surgeon dissects the soft tissues surrounding the tendon. This careful dissection is essential to expose the tendon without causing additional injury to the surrounding structures.
  • Step 3: Once the tendon is identified, the surgeon assesses the extent of the adhesions. The next step involves severing these adhesions, which are fibrous bands of scar tissue that have formed around the tendon, thereby restricting its movement.
  • Step 4: After the adhesions are released, the surgeon evaluates the range of motion of the tendon to ensure that the procedure has effectively restored mobility.
  • Step 5: The surgical wound is then closed in layers. This layered closure technique helps to promote optimal healing and reduces the risk of complications.
  • Step 6: Finally, a dressing is applied to the surgical site to protect it during the initial healing phase.

3. Post-Procedure

Post-procedure care following tenolysis of a single extensor tendon includes monitoring the surgical site for signs of infection and ensuring proper healing. Patients are typically advised on how to care for the dressing and may be instructed to limit movement of the foot to facilitate recovery. Physical therapy may be recommended to help restore strength and flexibility to the tendon and surrounding muscles. The expected recovery time can vary based on individual circumstances, but patients should be prepared for a rehabilitation period to regain full function of the foot and toes.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.
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.
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).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
