Official Description

Open treatment of carpometacarpal dislocation, other than thumb; complex, multiple, or delayed reduction

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 26686 refers to the open treatment of a carpometacarpal (CMC) dislocation, specifically for cases that are classified as complex, multiple, or those that have experienced delayed reduction. A carpometacarpal dislocation occurs when the bones at the base of the fingers, excluding the thumb, become dislocated from their normal position. This procedure involves a surgical approach where an incision is made on the dorsal side of the hand, allowing the surgeon to access the dislocated joint directly. The complexity of the dislocation may arise from previous dislocations or a delay in treatment, which can complicate the reduction process. The open reduction technique is utilized to realign the dislocated joint accurately, ensuring proper healing and function. This procedure is critical for restoring mobility and strength to the affected hand, particularly in cases where the dislocation has not been addressed promptly or has recurred multiple times.

1. Indications

The open treatment of carpometacarpal dislocation, as described by CPT® Code 26686, is indicated for specific conditions related to the dislocation of the carpometacarpal joints other than the thumb. These indications include:

  • Complex Dislocation A dislocation that is complicated by factors such as multiple previous dislocations or significant soft tissue injury.
  • Multiple Dislocations Instances where more than one carpometacarpal joint is dislocated, necessitating surgical intervention for proper alignment.
  • Delayed Reduction Situations where there has been a significant delay in the treatment of the dislocation, which may lead to complications in the healing process.

2. Procedure

The procedure for the open treatment of a complex carpometacarpal dislocation involves several critical steps, which are outlined as follows:

  • Step 1: Incision A dorsal incision is made over the affected carpometacarpal joint. This incision allows the surgeon to gain direct access to the dislocated joint, facilitating the subsequent steps of the procedure.
  • Step 2: Exposure The joint surface is carefully exposed by retracting the extensor tendons. This step is essential for providing a clear view of the dislocated joint and ensuring that all necessary structures are visible for repair.
  • Step 3: Joint Capsule Opening The joint capsule is opened to access the dislocated joint. This step is crucial for allowing the surgeon to manipulate the joint and perform the reduction effectively.
  • Step 4: Reduction The dislocation is reduced, meaning the bones are realigned into their proper anatomical position. This step may require careful manipulation to ensure that the joint is restored correctly.
  • Step 5: Internal Fixation If necessary, internal fixation is applied to maintain the alignment of the joint. Typically, wire fixation is used to secure the bones in place during the healing process.
  • Step 6: Joint Capsule Repair After the reduction and fixation, the joint capsule is repaired to restore its integrity and support the healing process.
  • Step 7: Wound Closure Finally, the incision is closed, completing the surgical procedure. Proper closure is essential to minimize the risk of infection and promote healing.

3. Post-Procedure

Post-procedure care following the open treatment of a complex carpometacarpal dislocation includes monitoring for signs of infection, managing pain, and ensuring proper immobilization of the hand to facilitate healing. Patients may be advised to follow specific rehabilitation protocols to restore function and strength to the affected joint. Follow-up appointments are essential to assess the healing process and determine when it is safe to resume normal activities. The expected recovery time may vary based on the complexity of the dislocation and the individual patient's healing response.

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.
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).
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.
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.)
