Medicare coverage for IVIG

Medicare provides coverage for IVIG and SCIG therapies in many instances, but navigating the details can sometimes be difficult. This guide will provide an overview of how IG therapies are covered under Medicare.

Medicare will provide coverage for IVIG based on:

  • The diagnosis
  • The location of therapy
  • The route of administration 

Diagnosis codes and other criteria are used to determine whether IVIG is covered by Medicare Part B. If you have a condition that is not covered by Part B, you may still be covered by Medicare Part D if your condition is listed as an FDA-approved IVIG indication.

Medicare IVIG Demonstration Project

The Medicare Intravenous Immune Globulin (IVIG) Demonstration Project is designed to assess the benefits of providing compensation for materials and services required for in-home IVIG administration for the treatment of primary humoral immunodeficiency

In this demonstration, Medicare Part B will give coverage for supplies and services required to provide immunoglobulins in the home to the registered beneficiaries who are not otherwise bedbound and receiving home health care aids. The demonstration is solely for beneficiaries who require IVIG for the treatment of PIDD or who presently use subcutaneous immune globulin (SCIG) to treat PIDD and want to transition to IVIG.

Eligibility criteria for participation in IVIG Demonstration

To participate in the IVIG Demonstration, a recipient needs to meet the following requirements:

  • Must be registered for Medicare Part B and be covered by Medicare Fee-For-Service.
  • Must have a confirmed diagnosis of primary immune deficiency disease (PIDD).
  • Must not be currently receiving home health care.
