20611

Arthrocentesis, aspiration and/or injection, major joint or bursa (e.g., shoulder, hip, knee, subacromial bursa); with ultrasound guidance, with permanent recording and reporting

This procedure involves the percutaneous aspiration of fluid from, or injection of therapeutic substances into, a major joint space or bursa (e.g., shoulder, hip, knee, subacromial bursa) with continuous or intermittent ultrasound guidance. The use of ultrasound guidance ensures accurate needle placement, minimizes patient discomfort, and reduces potential complications. The procedure requires permanent recording of ultrasound images demonstrating needle placement and a formal written report documenting the procedure, findings, and any substances injected. It is performed for both diagnostic purposes (e.g., fluid analysis) and therapeutic interventions (e.g., corticosteroid injection, viscosupplementation).

Clinical Indications

  • Diagnosis of joint effusion, arthritis, or bursitis (e.g., septic arthritis, gout, pseudogout, inflammatory arthritis) through synovial fluid aspiration and analysis.
  • Therapeutic relief of pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, bursitis, tendinitis, or other inflammatory arthropathies.
  • Removal of accumulated fluid (e.g., hemarthrosis, synovial effusion) causing pain, swelling, or restricted movement.
  • Administration of therapeutic agents (e.g., corticosteroids, local anesthetics, hyaluronic acid, platelet-rich plasma) into the joint or bursa.
  • Confirmation of needle placement accuracy in challenging joint spaces or for patients with altered anatomy where landmark-guided approaches may be less reliable.

Procedure Steps

  1. Patient positioning to optimize access to the target joint or bursa.
  2. Sterile preparation and draping of the injection site, followed by local anesthetic administration to the skin and subcutaneous tissues.
  3. Placement of the ultrasound probe to visualize the target joint/bursa, surrounding neurovascular structures, and plan the needle trajectory.
  4. Real-time ultrasound guidance used to advance the needle percutaneously into the joint space or bursa.
  5. Aspiration of synovial fluid (if indicated) for diagnostic analysis, followed by collection in appropriate specimen containers.
  6. Injection of therapeutic medication (e.g., corticosteroid, local anesthetic, viscosupplement) into the joint or bursa under direct ultrasound visualization.
  7. Withdrawal of the needle and application of a sterile dressing or bandage to the puncture site.
  8. Capture and storage of permanent ultrasound images documenting accurate needle placement within the target structure.
  9. Completion of a formal written report detailing the procedure, findings, aspirated fluid characteristics (if applicable), and substances injected.

Coding Guidelines

  • CPT code 20611 specifically includes ultrasound guidance, permanent recording, and reporting. Therefore, it is inappropriate to report separate ultrasound guidance codes (e.g., 76942) in conjunction with 20611 for the same joint or bursa.
  • This code is designated for major joints or bursae (e.g., shoulder, hip, knee, subacromial bursa). For intermediate joints (e.g., elbow, wrist, ankle), refer to code 20606, and for small joints (e.g., fingers, toes), refer to code 20604, each with appropriate guidance.
  • If multiple major joints or bursae are aspirated/injected with ultrasound guidance during the same encounter, report 20611 for each distinct site. Append modifier 59 (Distinct Procedural Service) or an appropriate anatomical modifier (e.g., RT/LT, Fx/Tx) to subsequent units to indicate separate and distinct services.
  • Thorough documentation is required, including the medical necessity, the specific joint/bursa treated, the type and volume of substances injected, a description of the ultrasound guidance used, and confirmation of permanent image recording and a written report.
  • The global surgical package for CPT 20611 is typically 0 days, meaning follow-up visits related to the procedure are generally billable unless a separate significant and identifiable E/M service is provided.
