Official Description

Arthroscopy, wrist, surgical; synovectomy, partial

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Surgical arthroscopy of the wrist is a minimally invasive procedure that involves the examination and treatment of the wrist joint through small incisions. Specifically, CPT® Code 29844 refers to a partial synovectomy, which is the surgical removal of a portion of the synovial membrane that lines the joint. This procedure is typically indicated for patients suffering from inflammation of the synovial tissue, often due to conditions such as rheumatoid arthritis. The synovial membrane can become thickened and inflamed, leading to pain and restricted movement in the wrist. By performing a partial synovectomy, the surgeon aims to alleviate symptoms, improve joint function, and enhance the overall quality of life for the patient. The procedure is performed under sterile conditions, utilizing specialized instruments and techniques to ensure precision and minimize recovery time. The use of a pneumatic tourniquet and wrist traction device during the procedure aids in better visualization and access to the joint structures, allowing for effective removal of the inflamed tissue while preserving healthy joint components.

1. Indications

Arthroscopy of the wrist with partial synovectomy is indicated for the following conditions:

  • Rheumatoid Arthritis - A chronic inflammatory disorder that affects the synovial membrane, leading to pain and swelling in the wrist.
  • Synovitis - Inflammation of the synovial membrane, which can cause joint pain and stiffness.
  • Joint Effusion - Accumulation of excess fluid in the joint space, often associated with inflammation.
  • Other Inflammatory Conditions - Various conditions that result in synovial inflammation and may benefit from the removal of inflamed tissue.

2. Procedure

The procedure for a partial synovectomy via wrist arthroscopy involves several key steps:

  • Step 1: Patient Positioning - The patient is placed in a supine position with the shoulder abducted to facilitate access to the wrist. This positioning is crucial for optimal surgical exposure.
  • Step 2: Application of Pneumatic Tourniquet - A pneumatic tourniquet is applied to the upper arm to minimize blood flow to the wrist, which helps reduce bleeding during the procedure.
  • Step 3: Traction Setup - The forearm is suspended in a wrist traction device, and weights of 7-10 lbs are applied to the second and third fingers. This distraction of the wrist joint enhances visualization of the joint structures.
  • Step 4: Portal Incision and Arthroscope Introduction - A portal incision is made over the posterior aspect of the wrist, through which the arthroscope is introduced to visualize the joint interior.
  • Step 5: Cannula Insertion - An additional portal incision is made to introduce a cannula, allowing for the passage of surgical instruments into the joint space.
  • Step 6: Examination and Tissue Removal - The wrist joint is thoroughly examined, and any inflamed synovial tissue is removed using a motorized suction shaving device, ensuring that only the affected tissue is excised.
  • Step 7: Additional Access as Needed - If necessary, further portal incisions are made to access the midcarpal joint, allowing for the removal of additional inflamed tissue in the same manner.
  • Step 8: Joint Flushing and Closure - Upon completion of the synovectomy, the joint is flushed with normal saline to clear any debris. The arthroscope and surgical instruments are then removed, and the portal incisions are closed securely.

3. Post-Procedure

After the partial synovectomy, patients can expect a recovery period that may involve rest and immobilization of the wrist to promote healing. Pain management strategies will be discussed, and physical therapy may be recommended to restore mobility and strength in the wrist. Follow-up appointments will be necessary to monitor the healing process and assess the effectiveness of the procedure. Patients should be advised on signs of complications, such as increased swelling, redness, or fever, which should prompt immediate medical attention.

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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
