Official Description

Tenotomy, flexor, finger, open, each tendon

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26455 refers to a tenotomy of the flexor tendon in the finger, performed through an open surgical approach. A tenotomy is a surgical procedure that involves the cutting or severing of a tendon, which in this case pertains specifically to the flexor tendons that allow for the bending of the fingers. During the procedure, an incision is made in the skin of the palm or finger, directly over the flexor tendon that is to be treated. This incision allows the surgeon to access the underlying soft tissues, which are carefully dissected to expose the tendon. Once the tendon is visible, it is incised, effectively severing or releasing it to alleviate tension or correct a deformity. The use of electrocautery is employed to control any bleeding that may occur during the procedure, ensuring a clear surgical field. After the tenotomy is completed, the surgeon meticulously closes the operative wound in layers to promote proper healing and minimize complications. It is important to note that CPT® Code 26455 should be reported for each separate finger flexor tendon on which a tenotomy is performed, distinguishing it from other related procedures such as those involving palmar flexor tendons, which are reported under a different code.

1. Indications

The tenotomy of the flexor tendon in the finger, as described by CPT® Code 26455, is indicated for various conditions that may affect the function of the finger. These indications may include:

  • Trigger Finger: A condition where a finger gets stuck in a bent position due to inflammation of the flexor tendon, causing pain and difficulty in movement.
  • Dupuytren's Contracture: A hand deformity that develops over years, causing one or more fingers to bend towards the palm due to thickening and shortening of the connective tissue in the palm.
  • Flexor Tendon Rupture: An injury where the flexor tendon is completely torn, often requiring surgical intervention to restore function.
  • Stenosing Tenosynovitis: Inflammation of the tendon sheath that can lead to pain and restricted movement of the finger.

2. Procedure

The procedure for performing a tenotomy of the flexor tendon in the finger involves several critical steps, which are outlined as follows:

  • Step 1: The patient is positioned comfortably, and the surgical site is prepared and draped in a sterile manner to minimize the risk of infection.
  • Step 2: An incision is made in the skin over the flexor tendon, typically located in the palm or along the finger. This incision is carefully planned to provide optimal access to the tendon while minimizing damage to surrounding tissues.
  • Step 3: The surgeon dissects the soft tissues surrounding the tendon to expose it fully. This step requires precision to avoid injury to nearby structures, such as nerves and blood vessels.
  • Step 4: Once the tendon is adequately exposed, the surgeon incises the tendon, effectively severing it. This release alleviates tension and addresses the underlying condition affecting finger movement.
  • Step 5: After the tenotomy is completed, any bleeding is controlled using electrocautery, which helps to coagulate blood vessels and maintain a clear surgical field.
  • Step 6: The final step involves closing the operative wound in layers. This layered closure technique is essential for proper healing and to reduce the risk of complications such as infection or scarring.

3. Post-Procedure

Following the tenotomy procedure, patients can expect specific post-operative care and recovery considerations. The surgical site will typically be bandaged, and patients may be advised to keep the hand elevated to reduce swelling. Pain management may be necessary, and the surgeon may prescribe analgesics to help alleviate discomfort. Patients are often instructed on how to care for the incision site to prevent infection and promote healing. Rehabilitation may be recommended, including physical therapy, to restore movement and strength in the finger. The recovery period can vary depending on the individual and the extent of the procedure, but follow-up appointments will be scheduled to monitor healing and assess the need for further intervention if necessary.

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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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).
