Official Description

Arthroscopy, elbow, surgical; synovectomy, complete

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 29836 refers to a surgical arthroscopy of the elbow that involves a complete synovectomy. In this context, 'arthroscopy' is a minimally invasive surgical technique that allows for the examination and treatment of joint conditions through small incisions. The term 'synovectomy' specifically denotes the surgical removal of the synovial membrane, which is the tissue lining the joint that can become inflamed or thickened due to various conditions, such as arthritis or other inflammatory diseases. This procedure is typically indicated when there is significant synovial pathology affecting the elbow joint, leading to pain, swelling, and reduced range of motion. The complete synovectomy entails addressing both the posterior and anterior compartments of the elbow, ensuring thorough removal of the diseased synovial tissue to alleviate symptoms and improve joint function. The patient is positioned in a way that facilitates access to the elbow joint, and the procedure is performed using specialized instruments designed for arthroscopic surgery, which minimizes trauma to surrounding tissues and promotes quicker recovery compared to open surgical techniques.

1. Indications

The procedure is indicated for patients experiencing significant synovial pathology in the elbow joint, which may include the following conditions:

  • Chronic Inflammation Persistent inflammation of the synovial membrane, often associated with conditions such as rheumatoid arthritis or other inflammatory arthropathies.
  • Synovial Hyperplasia Thickening of the synovial membrane that can lead to joint pain and dysfunction.
  • Joint Pain Severe pain in the elbow that is not responsive to conservative treatments, indicating the need for surgical intervention.
  • Limited Range of Motion Difficulty in moving the elbow joint due to synovial tissue proliferation or other related issues.

2. Procedure

The surgical procedure for CPT® Code 29836 involves several key steps to ensure a complete synovectomy of the elbow joint:

  • Step 1: Patient Positioning The patient is placed in a lateral decubitus position, which allows the upper arm to be supported while the forearm can swing freely. This positioning is crucial for optimal access to the elbow joint during the procedure.
  • Step 2: Portal Incisions Midlateral and posterior portal incisions are made to access the elbow joint. The posterior compartment is explored first, allowing the surgeon to assess the condition of the synovial tissue.
  • Step 3: Posterior Compartment Exploration The posterior compartment is examined, and if synovectomy is necessary, the synovium around the olecranon fossa is removed using an arthroscopic shaver. This step is critical for addressing any pathological tissue in the posterior area of the joint.
  • Step 4: Medial Gutter Treatment The medial gutter is addressed next, where small rongeurs are utilized to clear any obstructive tissue. The synovium is then grasped and carefully removed with a shaver, ensuring protection of the ulnar nerve during this process.
  • Step 5: Irrigation Upon completion of the posterior compartment work, the area is irrigated with saline solution to clear debris and ensure a clean surgical field.
  • Step 6: Anterior Portal Incisions Anterior portal incisions are then made to access the anterior compartment of the elbow. A retractor is placed in the proximal anterolateral portal to enhance visualization.
  • Step 7: Anterior Compartment Exploration The scope and surgical instruments are inserted through the anterolateral and proximal anteromedial portals to explore the anterior compartment. Synovectomy is performed in this area as well.
  • Step 8: Complete Synovectomy The shaver is used to remove the synovium from the humerus, working from proximal to distal and medial to lateral to ensure thorough removal of all affected tissue.
  • Step 9: Final Irrigation and Closure Once the synovectomy is complete, the anterior compartment is flushed with saline solution. The scope and instruments are then removed, and the portal incisions are closed to complete the procedure.

3. Post-Procedure

After the completion of the synovectomy, post-procedure care typically involves monitoring the patient for any immediate complications. Patients may be advised to rest the elbow and may require a period of immobilization to promote healing. Pain management strategies will be discussed, and physical therapy may be recommended to restore range of motion and strength in the elbow joint. Follow-up appointments will be necessary to assess recovery and ensure that the joint is healing properly.

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