A 55-year-old male with a history of osteoarthritis presents to the clinic with worsening pain and stiffness in his right knee. The patient has tried conservative management, including physical therapy and oral anti-inflammatory medications, with minimal relief. The orthopedic specialist decides to administer an intra-articular injection of a corticosteroid into the patient's right knee joint to reduce inflammation and provide pain relief. The procedure is performed in the office under sterile conditions, and the patient tolerates the injection well. What is the most appropriate CPT code for reporting this procedure?
Answer: C. 20610
Rationale: CPT code 20610 is appropriate for the aspiration and/or injection of a major joint, such as the knee, shoulder, or hip, without ultrasound guidance. In this scenario, the physician performed an intra-articular injection into the knee joint, which is considered a major joint. Therefore, 20610 is the correct code to use for this procedure. The other codes (20600 and 20605) correspond to injections into smaller joints, while 20611 includes ultrasound guidance, which was not mentioned in the scenario.
