Official Description

Arthroscopy, shoulder, surgical; debridement, extensive, 3 or more discrete structures (eg, humeral bone, humeral articular cartilage, glenoid bone, glenoid articular cartilage, biceps tendon, biceps anchor complex, labrum, articular capsule, articular side of the rotator cuff, bursal side of the rotator cuff, subacromial bursa, foreign body[ies])

Common Language Description

The CPT® Code 29823 refers to a surgical procedure known as arthroscopy of the shoulder, specifically involving extensive debridement of three or more discrete structures within the shoulder joint. Arthroscopy is a minimally invasive surgical technique that allows for the examination and treatment of joint conditions through small incisions. In this procedure, debridement is performed to remove unhealthy, dead, damaged, or infected tissue from the joint, which can help alleviate pain and restore function. The structures that may be involved in this extensive debridement include the humeral bone, humeral articular cartilage, glenoid bone, glenoid articular cartilage, biceps tendon, biceps anchor complex, labrum, articular capsule, and both the articular and bursal sides of the rotator cuff. Additionally, any foreign bodies present in the joint may also be removed during this procedure. The patient is typically positioned in either a lateral decubitus position with the arm suspended or in a beach chair position to facilitate access to the shoulder joint. This procedure is indicated when there is significant damage or disease affecting multiple structures within the shoulder, necessitating a thorough cleaning and repair to promote healing and improve joint function.

1. Indications

The procedure described by CPT® Code 29823 is indicated for patients experiencing significant shoulder joint issues that require extensive debridement. The following conditions may warrant this surgical intervention:

  • Extensive Joint Damage - Patients with severe damage to multiple structures within the shoulder joint, including bones, cartilage, and soft tissues.
  • Infection - Presence of infected tissue that needs to be removed to prevent further complications and promote healing.
  • Degenerative Conditions - Conditions such as osteoarthritis that lead to the deterioration of joint structures, necessitating debridement.
  • Trauma - Patients who have sustained injuries resulting in damage to the shoulder joint components, requiring surgical intervention for repair.
  • Foreign Bodies - The presence of foreign objects within the shoulder joint that may cause pain or impede function.

2. Procedure

The procedure for CPT® Code 29823 involves several critical steps to ensure effective debridement of the shoulder joint. The following outlines the procedural steps:

  • Step 1: Patient Positioning - The patient is positioned in either a lateral decubitus position with the arm suspended or in a beach chair position to provide optimal access to the shoulder joint.
  • Step 2: Portal Incision - Anterior and posterior portal incisions are made over the shoulder joint to create access points for the surgical instruments.
  • Step 3: Joint Expansion - A sterile saline solution is infused into the shoulder joint using an infusion pump. This step is crucial as it expands the joint space, allowing for better visualization and access to the internal structures.
  • Step 4: Diagnostic Arthroscopy - A diagnostic arthroscopy is performed to visualize the interior of the shoulder joint. This step allows the surgeon to identify the areas of diseased or damaged tissue that require debridement.
  • Step 5: Additional Portal Incisions - If necessary, additional portal incisions are made to facilitate the introduction of surgical tools and improve access to the surgical site.
  • Step 6: Debridement - A shaver is introduced into the joint, and the surgeon carefully debrides the identified diseased or damaged tissue, which may include cartilage, bone, capsule, tendon, and any foreign bodies. The goal is to clean the area and expose healthy tissue for optimal healing.

3. Post-Procedure

After the completion of the procedure, the patient will typically undergo a recovery period that may involve monitoring for any complications. Post-procedure care may include pain management, physical therapy, and instructions for activity restrictions to promote healing. The expected recovery time can vary based on the extent of the debridement and the individual patient's condition. Follow-up appointments will be necessary to assess the healing process and determine the appropriate rehabilitation plan.
