HCPCS Code J1569: Injection, immune globulin, (Gammagard liquid), non-lyophilized, (e.g., liquid), 500 mg

Gammagard liquid is used to treat immune-related conditions such as multifocal motor neuropathy and primary immunodeficiencies. It’s given when the immune system can’t produce enough antibodies to protect against infections.

Yes. J1569 covers Gammagard liquid infusions, whether they’re the initial session or part of additional sequential infusions. If an extra hour of infusion is needed, it must be billed separately using the correct add-on code.

Dosage must be recorded in 500 mg units, noting the exact amount infused, the route (IV), and whether it was part of a primary or sequential infusion. This ensures compliance with Medicare and Medicaid billing requirements.
