What it covers

G329 is the add-on for each additional bursa or complex joint, after the first billed as G328 (aspiration of a bursa or complex joint, with or without injection), to a maximum of 2 (J53).

A complex joint is any joint other than the knee, or a knee whose anatomy is distorted by lupus, dermatomyositis, rheumatoid arthritis, Still's disease, ankylosing spondylitis or another seronegative spondyloarthropathy (J53).

Billing rules

• Bill with G328 for the first bursa or complex joint; G329 is limited to 2 additional sites (J53).
• Not payable solely for injection of a complex joint; aspiration must be done (J53).
• Only one of G370, G371, G328 and G329 per bursa, joint or complex joint (J53).
• Olecranon bursa aspiration and/or injection is billed only as G370/G371, not G328/G329 (J53).
• Not payable with a surgical procedure on the same site or area (J53).
• Uninsured for injection of intra-articular viscosupplementation agents such as hyaluronic acid (J53).
