Mrs. Jones, an established patient, is seen by the rheumatologist for repeated pain in her left knee due to osteoarthritis. Today she presents with pain and swelling.

Question

Quizplus · Accepted Answer

The correct ICD-10-CM code for osteoarthritis of the left knee is M17.12. The CPT code 20610 is for arthrocentesis, aspiration and/or injection; major joint or bursa (e.g., shoulder, hip, knee joint, subacromial bursa) without ultrasound guidance, which matches the procedure described. J1100 is the HCPCS code for Dexamethasone sodium phosphate, 1 mg, and "5u" indicates the dosage used, which is 5 mg in this case. No E/M service was performed, so no E/M code is applicable.
