Retired: ALYGLO® (immune globulin intravenous, human-stwk), 10% Liquid – Correct Coding and Coverage
Joint DME MAC Publication
ALYGLO® (immune globulin intravenous, human-stwk), 10% Liquid (GC Biopharma Corp., Republic of Korea) is a sterile liquid preparation of highly purified and concentrated human immunoglobulin G (IgG) antibodies. The distribution of the IgG subclasses is similar to that of normal human plasma. ALYGLO® received FDA approval on December 15, 2023. ALYGLO™ is indicated for the treatment of primary humoral immunodeficiency (PI) in adults aged 17 years and older.
Medicare Coverage for IVIG
Intravenous immune globulin (IVIG) used for the treatment of primary immunodeficiency is covered under the Intravenous Immune Globulin benefit (IOM 100-2, Ch. 15, §50.6). For a beneficiary's IVIG to be eligible for reimbursement there are specific statutory payment policy requirements, discussed below, that must be met.
Intravenous immune globulin is covered if all the following criteria are met:
- It is an approved pooled plasma derivative for the treatment of primary immune deficiency disease; and
- The patient has a diagnosis of primary immune deficiency disease (See Diagnosis Codes that Support Medical Necessity section below); and
- The IVIG is administered in the home; and
- The treating physician has determined that administration of the IVIG in the patient's home is medically appropriate.
