Official Description

Fasciectomy, palm only, with or without Z-plasty, other local tissue rearrangement, or skin grafting (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26121 refers to a fasciectomy performed specifically on the palm of the hand. This surgical intervention is indicated for the excision of thickened fascia, which may occur in the palm alone or extend to the fingers. The primary goal of this procedure is to relieve flexion contractures that can impede finger movement and functionality. During the operation, a zigzag incision is typically made over the palm and, if necessary, the affected fingers. This incision allows for the careful elevation of the skin and subcutaneous tissue, exposing the palmar fascia and the pretentious fascial cord beneath. Surgeons meticulously dissect the soft tissue at the metacarpal head, ensuring that the digital nerves and arteries adjacent to the tendon cords are identified and preserved throughout the procedure. The thickened fascia is progressively elevated from the proximal palm to the metacarpal head, and once fully detached from the surrounding nerves and vessels, it is excised. This excision effectively frees the underlying tendon, alleviating the flexion contracture of the affected finger. Following the removal of the thickened fascia, the soft tissues in the palm are rearranged as necessary to cover and protect the underlying structures. The surgical site is then closed, either by suturing the zigzag incision or by utilizing a skin graft if required. It is important to note that if the incision extends over the proximal interphalangeal joint and involves the removal of the fascial cord from a single finger, CPT® Code 26123 should be used. Additionally, for each additional finger from which the fascial cord is excised, CPT® Code 26125 is applicable.

1. Indications

The fasciectomy procedure described by CPT® Code 26121 is indicated for the treatment of conditions characterized by thickened fascia in the palm, which may also involve the fingers. This procedure is typically performed to address flexion contractures that restrict movement and functionality of the fingers. The following conditions may warrant this surgical intervention:

  • Dupuytren's Contracture - A condition where the fascia in the palm thickens and shortens, leading to the bending of one or more fingers.
  • Palmar Fibromatosis - A benign condition resulting in the formation of nodules and thickening of the palmar fascia.
  • Other Contractures - Any other conditions that result in the thickening of the palmar fascia, causing functional impairment of the hand.

2. Procedure

The procedure for CPT® Code 26121 involves several critical steps to ensure the effective excision of the thickened fascia. The following outlines the procedural steps:

  • Step 1: Incision - A zigzag incision is made over the palm and, if necessary, the affected fingers. This incision design helps to minimize scarring and allows for better access to the underlying structures.
  • Step 2: Elevation of Skin and Tissue - The skin and subcutaneous tissue are carefully elevated off the palmar fascia and the pretentious fascial cord. This step is crucial for exposing the thickened fascia that needs to be excised.
  • Step 3: Dissection of Soft Tissue - At the metacarpal head, the surgeon meticulously dissects the soft tissue to identify and protect the digital nerves and arteries located on either side of the tendon cords. This careful dissection is essential to prevent damage to these critical structures during the procedure.
  • Step 4: Elevation of Thickened Fascia - The thickened fascia over the affected tendon is progressively elevated from the proximal aspect of the palm to the head of the metacarpal. This step involves careful manipulation to ensure that the fascia is completely freed from surrounding nerves and vessels.
  • Step 5: Excision of Fascia - Once the fascial cord is fully detached, the thickened fascia is excised. This excision relieves the flexion contracture of the affected finger, restoring mobility.
  • Step 6: Soft Tissue Rearrangement - After the excision, the soft tissues in the palm are rearranged as necessary to cover and protect the underlying structures, ensuring proper healing.
  • Step 7: Closure - The zigzag incision is then closed, either by suturing or, if required, a skin graft is harvested and used to close the surgical wound.

3. Post-Procedure

Post-procedure care following a fasciectomy involves monitoring the surgical site for signs of infection and ensuring proper healing. Patients may be advised to keep the hand elevated to reduce swelling and to follow specific instructions regarding wound care. Rehabilitation may be necessary to restore full function of the hand, which can include physical therapy to improve range of motion and strength. The expected recovery time can vary based on the extent of the surgery and the individual patient's healing process. Follow-up appointments are essential to assess the healing progress and to address any complications that may arise.

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).
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).
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.
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).
