Deep Dive: IVIG & SCIG Therapy

IVIG is a cornerstone of what we do. IVIG uses pooled antibodies to treat conditions like Primary Immunodeficiency and CIDP. Dosing is weight-based and given every few weeks. Because it's expensive, payors scrutinize every single detail.

⚠️ Critical: Documentation is Everything

One missing lab result and the authorization gets denied. For IVIG/PI, we need IgG levels. For CIDP, we need EMG studies. Knowing this checklist helps you coach your referral sources to send complete packets the first time.

⭐ Pro Tip: The Script Wording

Coach your referring physicians to write the prescription as "IVIG, pharmacist to determine brand." This small change saves enormous headaches when specific brands are on backorder due to plasma shortages. It's a simple ask that prevents delays for the patient.
