Official Description

Tenotomy, open, flexor or extensor tendon, forearm and/or wrist, single, each tendon

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25290 refers to an open tenotomy of either a flexor or extensor tendon located in the forearm and/or wrist. A tenotomy is a surgical procedure that involves the cutting or severing of a tendon, which is a fibrous connective tissue that attaches muscle to bone. In this specific procedure, an incision is made in the skin over the tendon that is targeted for the tenotomy. This incision allows the surgeon to access the tendon directly. Once the tendon is exposed through careful dissection of the surrounding soft tissues, the surgeon proceeds to incise the tendon, effectively severing or releasing it. This action may be necessary for various clinical reasons, such as to relieve tension, correct deformities, or address tendon-related injuries. After the tendon has been incised, any bleeding that occurs is typically controlled using electrocautery, a technique that uses electrical current to coagulate blood vessels. Finally, the surgical site is closed in layers to promote proper healing and minimize complications. It is important to note that CPT® Code 25290 should be reported for each individual tendon on which the tenotomy is performed, ensuring accurate coding and billing for the procedure.

1. Indications

The indications for performing an open tenotomy of a flexor or extensor tendon in the forearm and/or wrist may include the following conditions:

  • Flexor tendon injuries: These injuries may occur due to trauma or overuse, leading to pain, dysfunction, or limited range of motion in the affected area.
  • Extensor tendon injuries: Similar to flexor injuries, extensor tendon injuries can result from acute trauma or chronic conditions, causing impairment in hand function and movement.
  • Contractures: Conditions such as Dupuytren's contracture may necessitate a tenotomy to release the affected tendon and restore normal function.
  • Tendonitis: Chronic inflammation of the tendon may require surgical intervention to alleviate symptoms and improve mobility.

2. Procedure

The procedure for an open tenotomy of a flexor or extensor tendon involves several key steps:

  • Step 1: The patient is positioned appropriately to allow optimal access to the forearm or wrist. The surgical site is then prepared and draped in a sterile manner to minimize the risk of infection.
  • Step 2: An incision is made in the skin directly over the tendon that is to be incised. This incision is carefully planned to provide adequate exposure while minimizing damage to surrounding tissues.
  • Step 3: The surgeon dissects through the soft tissues, including fascia and muscle, to expose the targeted tendon. This step requires precision to avoid injury to nearby structures.
  • Step 4: Once the tendon is fully exposed, the surgeon performs the tenotomy by incising the tendon. This may involve severing the tendon completely or partially, depending on the clinical indication.
  • Step 5: After the tendon has been incised, any bleeding is controlled using electrocautery. This technique helps to coagulate blood vessels and minimize blood loss during the procedure.
  • Step 6: Following the completion of the tenotomy, the surgeon closes the operative wound in layers. This typically involves suturing the deeper tissues first, followed by the skin, to ensure proper healing and reduce the risk of complications.

3. Post-Procedure

After the open tenotomy procedure, patients may require specific post-operative care to ensure optimal recovery. This may include immobilization of the affected area to allow for healing, pain management strategies, and instructions for wound care. Patients are often advised to follow up with their healthcare provider to monitor the healing process and assess the need for rehabilitation or physical therapy to restore function and strength in the affected tendon. The expected recovery time may vary based on the extent of the procedure and the individual patient's healing response.

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).
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
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
SG Ambulatory surgical center (asc) facility service
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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.
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.
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.
