Official Description

Fasciectomy, partial palmar with release of single digit including proximal interphalangeal joint, 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 CPT® Code 26123 refers to a surgical procedure known as a partial palmar fasciectomy, which involves the excision of thickened fascia in the palm and potentially the fingers. This procedure is specifically performed on a single digit, including the proximal interphalangeal joint, and may incorporate techniques such as Z-plasty, local tissue rearrangement, or skin grafting, which includes the process of obtaining a graft if necessary. The primary goal of this procedure is to alleviate the flexion contracture of the affected finger by removing the thickened fascia that restricts movement. During the operation, a zigzag incision is typically made over the palm and the affected fingers to access the underlying structures. The surgeon carefully elevates the skin and subcutaneous tissue to expose the palmar fascia and the pretendinous fascial cord. This meticulous dissection allows for the identification and protection of the digital nerves and arteries adjacent to the tendon cords. Once the thickened fascia is fully elevated from the proximal palm to the metacarpal head, it is excised, thereby freeing the underlying tendon. The procedure concludes with the rearrangement of soft tissues in the palm to ensure adequate coverage and protection of the underlying structures, followed by the closure of the zigzag incision or the application of a skin graft if required. This code is specifically utilized when the incision extends over the proximal interphalangeal joint and involves the removal of the fascial cord from a single finger, while additional fingers treated in a similar manner would be coded separately under CPT® Code 26125.

1. Indications

The procedure described by CPT® Code 26123 is indicated for patients presenting with conditions that involve thickened fascia in the palm and fingers, which may lead to flexion contractures. The following conditions may warrant this surgical intervention:

  • Dupuytren's Contracture - A condition characterized by the thickening and shortening of the palmar fascia, leading to the inability to fully extend the fingers.
  • Palmar Fibromatosis - A benign condition where nodules form in the palmar fascia, causing discomfort and functional limitations.
  • Progressive Flexion Contractures - Situations where the thickened fascia progressively restricts finger movement, necessitating surgical release to restore function.

2. Procedure

The surgical procedure associated with CPT® Code 26123 involves several critical steps to ensure effective treatment of the affected digit. The following procedural steps are outlined:

  • Step 1: Incision - A zigzag incision is made over the palm and the affected fingers. This incision design is chosen to allow for optimal access to the underlying structures while minimizing tension on the skin during closure.
  • Step 2: Elevation of Skin and Subcutaneous Tissue - The skin and subcutaneous tissue are carefully elevated off the palmar fascia and the pretendinous 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 nerve and vascular injury 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 structures.
  • Step 5: Excision of Fascia - Once the fascial cord is fully liberated from the digital nerves and vessels, the thickened fascia is excised. This excision is critical for relieving the flexion contracture of the affected finger, allowing for improved 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. This may involve suturing techniques that ensure proper healing and function.
  • Step 7: Closure - The zigzag incision is then closed, or if required, a skin graft is harvested and utilized to close the surgical wound. The choice between direct closure and grafting depends on the extent of tissue excised and the surgeon's assessment of the wound.

3. Post-Procedure

Post-procedure care following a fasciectomy involves monitoring the surgical site for signs of infection and ensuring proper healing. Patients are typically advised on wound care, which may include keeping the incision clean and dry. Rehabilitation may be necessary to restore function and mobility in the affected finger, often involving physical therapy to improve range of motion and strength. The expected recovery time can vary based on the extent of the surgery and individual healing responses, but patients should be informed about the importance of following up with their healthcare provider to assess healing and address any complications that may arise.

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).
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 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.
73 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure prior to the administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.
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).
