Is Gamifant Covered by Aetna?

Gamifant (emapalumab-lzsg) is not on Aetna's standard formulary but is covered through prior authorization for FDA-approved indications. Coverage is restricted to:

  • Primary hemophagocytic lymphohistiocytosis (HLH) in patients with refractory, recurrent, or progressive disease
  • Patients who are intolerant to conventional HLH therapy
  • Use in combination with dexamethasone as specified in FDA labeling

Which Aetna Plans Cover Gamifant:

  • Aetna commercial plans (PPO, HMO)
  • Aetna Better Health (Florida Medicaid)
  • Aetna Medicare Advantage plans
Note: Gamifant is billed under the medical benefit (HCPCS J9210), not the pharmacy benefit, and must be dispensed through an Aetna-approved specialty pharmacy like CVS Specialty.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
"HLH diagnosis not confirmed" Submit complete HLH-2004 checklist with lab values and dates HLH-2004 diagnostic criteria with specific results
"Step therapy not met" Document conventional therapy trials and outcomes Treatment records showing etoposide, steroid, cyclosporine use/failure
"Missing infection workup" Complete TB and hepatitis screening Lab results, imaging, prophylaxis plan
"Not medically necessary" Cite FDA approval and published guidelines FDA label, treatment guidelines
"Experimental/investigational" Reference FDA approval for primary HLH FDA approval letter, package insert
From our advocates: "We've seen denials overturned when providers submitted a detailed timeline showing how conventional therapies were tried and failed, with specific dates and lab values. The key is being thorough and systematic in documenting the HLH-2004 criteria—don't assume the reviewer knows what to look for."
