How to Get Gamifant (Emapalumab) Covered by Aetna in Ohio: Prior Authorization, Appeals & Step Therapy Guide

Answer Box: Getting Gamifant Covered by Aetna in Ohio

Aetna covers Gamifant (emapalumab) for primary hemophagocytic lymphohistiocytosis (HLH) in Ohio when strict criteria are met. The fastest path to approval requires: (1) documenting primary HLH diagnosis using HLH-2004 criteria or genetic testing, (2) proving failure/intolerance to conventional therapy (etoposide + dexamethasone), and (3) submitting prior authorization through Aetna's specialty pharmacy pathway. Start by having your hematologist gather complete treatment history and lab results, then submit the PA request via Aetna's provider portal. If denied, Ohio residents have 180 days to request external review through the Ohio Department of Insurance.

Plan Types & Network Requirements

Aetna offers several plan types in Ohio, each with different implications for Gamifant coverage:

Commercial Plans (HMO/PPO/EPO): All require prior authorization for Gamifant, but PPO plans may offer more flexibility in specialist access. HMO members need referrals to hematologists, while PPO members can typically see specialists directly.

Medicare Advantage: Follow Medicare Part B guidelines with additional Aetna requirements. Members who received emapalumab within the past 365 days are exempt from step therapy requirements.

Medicaid Plans: Ohio Medicaid managed care plans administered by Aetna follow Ohio Administrative Code 5160-1-01 for medical necessity determinations.

Tip: Confirm your plan type and network status before starting treatment. Out-of-network providers may require additional authorization steps.

Formulary Status & Coverage Tiers

Gamifant is classified as a specialty medication under Aetna's medical benefit, not the standard pharmacy benefit. This means:

  • Tier Status: Specialty tier requiring prior authorization
  • Covered Indication: Primary HLH only (not secondary/acquired HLH)
  • Billing Code: HCPCS J9210 with ICD-10 diagnosis code D76.1
  • Administration: Must be given in combination with dexamethasone

Counterforce Health specializes in navigating these complex specialty drug requirements, helping patients and providers prepare comprehensive appeals that address payer-specific formulary restrictions and coverage criteria.

HLH-2004 Diagnostic Criteria

Aetna requires documentation of primary HLH through either:

Genetic Confirmation: Mutations in PRF1, UNC13D, STX11, or STXBP2 genes

OR Clinical Criteria (5 out of 8):

  • Fever
  • Splenomegaly
  • Cytopenias (≥2 cell lines: hemoglobin <9 g/dL, platelets <100,000/μL, neutrophils <1,000/μL)
  • Hypertriglyceridemia (≥265 mg/dL) or hypofibrinogenemia (≤150 mg/dL)
  • Hemophagocytosis in bone marrow, spleen, lymph nodes, or liver
  • Low/absent NK cell activity
  • Ferritin ≥500 mcg/L
  • Soluble CD25 ≥2,400 U/mL

Step Therapy Documentation

Conventional Therapy Requirements: Patients must demonstrate failure, intolerance, or contraindications to standard HLH treatment before Gamifant approval. Required documentation includes:

  1. Treatment History: Detailed records of etoposide + dexamethasone therapy
  2. Clinical Response: Lab values, symptom progression, treatment duration
  3. Adverse Events: Documentation of intolerance or contraindications
  4. Specialist Assessment: Hematologist's evaluation of treatment failure

Medicare Advantage Exception: Step therapy doesn't apply if the patient received emapalumab within the past 365 days.

Note: Incomplete step therapy documentation is the most common reason for initial denials. Ensure all prior treatments are thoroughly documented with dates, doses, and outcomes.

Specialty Pharmacy Process

Gamifant is distributed through Aetna's specialty pharmacy network, typically CVS Specialty:

Step-by-Step Process

  1. Prescription Routing: Your doctor submits the prescription to CVS Specialty or another Aetna-approved specialty pharmacy
  2. Prior Authorization: The pharmacy initiates the PA request with your clinical documentation
  3. Review Process: Aetna reviews within 30-45 days (expedited reviews available for urgent cases)
  4. Approval Duration: Initial approvals typically last 6 months with required reauthorization
  5. Delivery Setup: Once approved, the specialty pharmacy coordinates delivery and administration

Common Denial Reasons & Solutions

Contact Information:

From Our Advocates: We've seen cases where initial denials citing "experimental" status were overturned on external review when providers submitted comprehensive documentation showing the patient met all FDA-approved criteria. The key was including both genetic confirmation and detailed treatment history in a well-organized appeal package.

Cost-Sharing Considerations

Specialty Tier Costs: Gamifant typically falls under the highest cost-sharing tier, which may include:

  • High deductibles before coverage begins
  • Coinsurance (percentage of drug cost) rather than fixed copays
  • Annual out-of-pocket maximums that provide protection

Financial Assistance Options:

  • Gamifant Cares Patient Support: Manufacturer copay assistance and case management
  • State pharmaceutical assistance programs (verify eligibility)
  • Hospital charity care programs for infusion costs
