Injection of Gammagard Liquid, a ready-to-use human immune globulin solution

This code represents the administration of Gammagard Liquid, a non-lyophilized immune globulin product derived from human plasma. It is used to provide passive immunity and modulate the immune system in patients with primary humoral immunodeficiency (PI) or other immune-related disorders.

This code is used when Gammagard Liquid is administered intravenously for conditions such as primary immunodeficiency diseases, chronic lymphocytic leukemia (CLL) with hypogammaglobulinemia, or idiopathic thrombocytopenic purpura (ITP). Documentation should clearly specify the product name (Gammagard Liquid), the route of administration, and the dosage.

• Ensure the documentation explicitly states "Gammagard Liquid" to differentiate it from other immune globulin products.
• Do not confuse this with lyophilized (freeze-dried) immune globulin preparations, which have different HCPCS codes.
• Report the appropriate administration code (e.g., CPT 96365, 96366) in conjunction with this supply code.
