How to bill it
Bill G370A for the first site and G371A for each additional site, up to 5 (J53).
In the office, add E542A to the G370A line (J53).
If the injection was the only reason for the visit, add G700A. If you also assessed the patient and bill an assessment, leave G700A off; the procedure is paid in addition to the assessment (J3).
If you aspirate a complex joint or a bursa, bill G328A (and G329A for extra complex joints) instead of G370A for that joint. G328/G329 aren't for injection alone (J53).
