ABSTRACT
Intravenous immunoglobulin (IVIG) has been shown in controlled studies to be useful in treating numerous neurological conditions (Table 1). Despite verification by published data, reimbursement for treatment is not guaranteed. Insurance companies consider many variables before rendering payment: Food and Drug Administration (FDA) approval, accuracy of International Classification of Diseases (ICD) coding, documentation of the diagnosis, pre-certification and site of infusion. Coverage varies widely among private insurance companies, and Medicare and Medicaid carriers.
