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.

|---|---|---|
| "HLH diagnosis not confirmed" | Submit complete HLH-2004 checklist with lab values and dates | HLH-2004 diagnostic criteria with specific results |

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."
