Official Description

Fasciotomy, palmar (eg, Dupuytren's contracture); percutaneous

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Fasciotomy, specifically for the treatment of Dupuytren's contracture, is a surgical procedure aimed at alleviating the symptoms associated with this condition. Dupuytren's contracture is characterized by the abnormal thickening and tightening of the fibrous tissue located beneath the skin of the hand and fingers. This condition leads to the formation of nodules and cords that can cause one or more fingers to bend towards the palm, resulting in a flexion contracture. Although the condition itself is typically painless, it significantly impairs the ability to fully extend the affected fingers, which can hinder daily activities and overall hand function. The procedure coded as CPT® 26040 involves a percutaneous approach, where a small stab incision is made in the palm over the area of thickened tissue. Through this incision, the fibrous tissue is carefully incised to release the contracture, thereby restoring the ability to extend the fingers. This method is less invasive compared to traditional surgical techniques, which may involve larger incisions and more extensive tissue manipulation.

1. Indications

The procedure coded as CPT® 26040 is indicated for patients suffering from Dupuytren's contracture, which is characterized by the following conditions:

  • Flexion Contracture - The inability to fully extend one or more fingers due to the thickening of the fibrous tissue beneath the skin.
  • Functional Impairment - Difficulty in performing daily activities that require full hand function, such as gripping or holding objects.
  • Progressive Symptoms - Worsening of the contracture over time, leading to increased limitation in finger extension.

2. Procedure

The procedure for CPT® 26040 involves several key steps that are crucial for effectively addressing Dupuytren's contracture:

  • Step 1: Preparation - The patient is positioned comfortably, and the hand is prepared for the procedure. This includes cleaning the area to minimize the risk of infection.
  • Step 2: Anesthesia - Local anesthesia is administered to the palm to ensure the patient remains comfortable and pain-free during the procedure.
  • Step 3: Incision - A small stab incision is made in the palm directly over the region of thickened fibrous tissue. This incision is minimal, allowing for a less invasive approach.
  • Step 4: Tissue Incision - Through the stab incision, the surgeon carefully incises the thickened fibrous tissue. This step is critical as it releases the tension caused by the contracture, allowing for improved finger extension.
  • Step 5: Closure - After the fibrous tissue has been adequately incised, the incision may be closed if necessary, although in many cases, the small size of the incision may not require suturing.

3. Post-Procedure

Following the fasciotomy procedure, patients can expect a recovery period that may involve some swelling and discomfort in the hand. Post-procedure care typically includes instructions for wound care to prevent infection and promote healing. Patients may also be advised to engage in hand therapy or exercises to regain full range of motion and strength in the fingers. Regular follow-up appointments may be necessary to monitor the healing process and assess the effectiveness of the procedure in restoring finger extension.

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).
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.
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.)
F4 Left hand, fifth digit
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).
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.)
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).
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
