Arthrodesis of the metacarpophalangeal (MCP) joint is a surgical procedure aimed at fusing the bones of the MCP joint, which connects the metacarpal bone of the hand to the proximal phalanx of the finger. This procedure is typically indicated for patients suffering from conditions such as arthritis or instability of the MCP joint, which can lead to pain and functional impairment. The surgery involves making an incision over the MCP joint to access the joint capsule, allowing for a thorough inspection of the joint surfaces. During the procedure, the articular cartilage from both the metacarpal head and the phalanx is excised to prepare the surfaces for fusion. The metacarpal is then smoothed and reshaped to ensure a proper fit with the phalanx. In some cases, internal fixation devices, such as pins or wires, may be utilized to maintain the desired position of the joint during the healing process. Additionally, in the case of CPT® Code 26852, a bone autograft is harvested from the iliac crest, which involves making a separate incision to obtain the necessary bone material. This graft is then shaped to fit the defect created by the excision of cartilage and is secured in place to facilitate the fusion of the joint. The procedure concludes with the repair of soft tissues in layers and the application of a short arm cast to support the hand during recovery.

Arthrodesis of the metacarpophalangeal (MCP) joint is performed for specific indications, primarily related to joint dysfunction and instability. The following conditions may warrant this surgical intervention:
The procedure for arthrodesis of the MCP joint involves several critical steps to ensure successful fusion and recovery. Each step is detailed as follows:
After the arthrodesis procedure, patients can expect specific post-operative care and recovery protocols. The application of a short arm cast is intended to immobilize the MCP joint and protect the surgical site during the healing process. Patients are typically advised to limit movement of the affected hand to promote proper fusion of the joint. Follow-up appointments are essential to monitor the healing progress and to assess the success of the fusion. Pain management strategies may be implemented, and physical therapy may be recommended once the initial healing phase is complete to restore function and strength to the hand.

| 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). | 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). | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | CR | Catastrophe/disaster related | F1 | Left hand, second digit | F2 | Left hand, third digit | F3 | Left hand, fourth digit | F4 | Left hand, fifth digit | F5 | Right hand, thumb | F6 | Right hand, second digit | F7 | Right hand, third digit | F8 | Right hand, fourth digit | F9 | Right hand, fifth digit | FA | Left hand, thumb | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | SG | Ambulatory surgical center (asc) facility service | T5 | Right foot, great toe | TA | Left foot, great toe | XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
