CPT® Code 90284

Immune globulins are specialized immunizing agents that provide effective, short-term, passive immunity by delivering antibodies directly into the recipient's system. Unlike active immunization, where the body's immune system is stimulated to produce its own antibodies, passive immunity involves the administration of pre-formed antibodies. This method of protection is particularly beneficial for individuals who may have compromised immune systems or are at increased risk of infections. The immune globulin used in this context is derived from a concentrated solution of antibodies that are pooled from the blood of multiple donors, ensuring a broad spectrum of antibody coverage. The subcutaneous administration of human immune globulin (SCIg) is specifically designed to prevent or mitigate the severity of certain infections in vulnerable patients. Additionally, SCIg is utilized in the management of various medical conditions, including immune system deficiencies, thrombocytopenia, and Kawasaki syndrome. The CPT® Code 90284 specifically reports the administration of human immune globulin for subcutaneous infusion, with each unit representing 100 mg of the product used, thereby facilitating accurate coding and billing for this therapeutic intervention.
