Summary & Overview
CPT 20605: Needle Aspiration/Injection of Intermediate Joint or Bursa
CPT code 20605 represents a common musculoskeletal procedure: needle aspiration and/or injection of an intermediate joint or bursa performed without ultrasound guidance. Nationally, this code is used across ambulatory settings to manage joint effusions, inflammatory conditions, and to deliver therapeutic agents directly into periarticular structures. It matters because it is frequently billed in outpatient and office-based practices and intersects clinical care, billing accuracy, and payer coverage policies.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations tied to this procedure. The publication also summarizes benchmark utilization patterns, reimbursement considerations, and recent policy guidance that affect billing and coverage for non-image-guided joint/bursa aspiration and injection.
The content provides clinicians, coders, and policy staff with actionable reference points: the clinical description of the service, payer coverage landscape, and what to review when coding or auditing claims for this procedure. Data not available in the input is identified where relevant.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A 56-year-old patient presents to an outpatient orthopedics clinic with a 2-week history of progressive swelling, pain, and reduced range of motion in the right knee. The clinician performs a focused history and musculoskeletal exam, noting joint effusion and crepitus. Point-of-care imaging (plain radiographs) rules out acute fracture; ultrasound is available but not used for the procedure. After informed consent, the provider performs an aseptic joint aspiration (arthrocentesis) of the knee using a sterile needle and syringe to remove synovial fluid for diagnostic analysis and relieves pressure. The clinician may then inject an intra-articular corticosteroid for therapeutic effect during the same encounter. The procedure is performed in an outpatient clinic procedure room or urgent care setting; standard documentation includes indication, neurovascular status of the extremity, technique (needle gauge, approach), amount and character of fluid obtained, any medication injected (name, dose, lot), patient tolerance, and post-procedure instructions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management (E/M) service by the same physician on the same day as the procedure | Use when a distinct E/M visit addresses a separate problem beyond the arthrocentesis. |
