What This Guide Covers

This comprehensive guide helps patients with primary hemophagocytic lymphohistiocytosis (HLH) and their care teams navigate Aetna CVS Health's prior authorization process for Gamifant (emapalumab-lzsg) in Illinois. Whether you're facing an initial request, denial appeal, or reauthorization, we'll walk you through each step with specific forms, timelines, and scripts.

Gamifant is a specialized anti-interferon gamma monoclonal antibody approved for primary HLH patients with refractory, recurrent, or progressive disease. Given its high cost and specialized use, Aetna requires thorough documentation of medical necessity before approval.

Before You Start: Verify Your Coverage

Check Your Plan Type and Benefits

First, confirm your Aetna plan details:

  • Plan type: Commercial, Medicare Advantage, or Medicaid managed care
  • Specialty pharmacy benefit: Most Gamifant prescriptions route through CVS Specialty Pharmacy
  • Medical vs. pharmacy benefit: Gamifant is typically covered under the medical benefit for IV infusions
Tip: Call the member services number on your insurance card (typically 1-888-792-3862) to verify your specialty drug benefits and any specific requirements for HLH treatments.

Confirm In-Network Status

Ensure your hematologist and infusion center are in-network with Aetna. Out-of-network providers face additional hurdles and higher patient costs. Use Aetna's provider directory to verify network status.
