How to Get Ferriprox (Deferiprone) Covered by Aetna in New York: Prior Authorization, Appeals, and Step Therapy Guide

Answer Box: Getting Ferriprox Covered by Aetna in New York

Aetna requires prior authorization for Ferriprox (deferiprone) with strict criteria: documented transfusional iron overload (ferritin >1000 mcg/L), diagnosis of thalassemia or sickle cell disease, and an ANC monitoring plan.

  1. Gather ferritin levels, transfusion records, and ANC monitoring plan
  2. Submit PA through CVS Caremark with complete clinical documentation
  3. If denied, file internal appeal within 60 days, then external appeal through NY DFS within 180 days

Aetna's Coverage Policy Overview

Aetna (CVS Health) treats Ferriprox as a specialty medication requiring prior authorization across most plan types in New York. The drug may be excluded from certain formularies in favor of preferred iron chelators like deferasirox (Exjade/Jadenu) or deferoxamine (Desferal).

Plan Types and Coverage

  • Commercial PPO/HMO: Prior authorization required; may be non-formulary
  • Medicare Advantage: Follows Medicare Part D guidelines with additional Aetna criteria
  • Medicaid Managed Care: Subject to New York State Medicaid preferred drug list

CVS Caremark typically handles specialty medication authorizations, while CVS Specialty Pharmacy manages dispensing for approved patients.

Note: Coverage varies significantly by employer group and specific plan design. Always verify your plan's current formulary through the Aetna member portal or by calling the number on your insurance card.

Medical Necessity Requirements

Aetna's 2024 policy for Ferriprox requires meeting specific clinical criteria based on FDA labeling and established guidelines.

Primary Indications

  • Transfusional iron overload in patients with:
    • Thalassemia syndromes (oral solution ≥3 years, tablets ≥8 years)
    • Sickle cell disease (oral solution ≥3 years, tablets ≥8 years)
    • Other chronic anemias requiring regular transfusions

Clinical Criteria for Initial Approval

Requirement Specification Documentation Needed
Diagnosis Confirmed transfusional iron overload ICD-10 codes, transfusion records
Ferritin Level Pretreatment serum ferritin >1000 mcg/L Lab report within 30 days
Exclusions No myelodysplastic syndrome or Diamond Blackfan anemia Medical records, pathology reports
Dosing Must not exceed 99 mg/kg/day Prescriber attestation
Monitoring Plan ANC monitoring protocol established Written monitoring plan

Continuation Criteria

For renewals every 6 months, Aetna requires:

  • Demonstrated clinical benefit (reduced serum ferritin from baseline)
  • Current serum ferritin level
  • Serum ferritin not consistently <500 mcg/L
  • Ongoing ANC monitoring compliance

Step Therapy and Exceptions

Many Aetna plans require step therapy, meaning patients must try and fail other iron chelators before Ferriprox approval.

Typical Step Therapy Sequence

  1. First-line: Deferoxamine (Desferal) - injectable
  2. Second-line: Deferasirox (Exjade/Jadenu) - oral
  3. Third-line: Ferriprox (deferiprone) - oral

Medical Exception Criteria

Step therapy can be bypassed if you document:

  • Contraindication to preferred agents (renal impairment, hearing loss with deferoxamine)
  • Previous intolerance with specific adverse events documented
  • Clinical failure despite adequate trial (persistent iron overload)
  • Combination therapy medically necessary per specialist recommendation
Tip: Document specific reasons for step therapy exception in your initial PA submission to avoid delays.

What if Ferriprox is not on my Aetna formulary? You can request a formulary exception by demonstrating medical necessity and documenting failures or contraindications to preferred alternatives.

Can I get expedited appeals for Ferriprox denials? Yes, if you can demonstrate urgent medical need (risk to life, health, or function). Both internal and external expedited appeals are available with 72-hour decision timelines.

Does step therapy apply if I tried other chelators outside New York? Yes, documented trials from other states count toward step therapy requirements. Provide complete medical records showing prior therapy attempts and outcomes.

What happens if my ANC drops during Ferriprox therapy? Ferriprox must be discontinued immediately if ANC falls below 1.5 × 10⁹/L. Notify your prescriber and Aetna, as this may affect ongoing authorization.

Can I appeal to New York if I have an out-of-state Aetna plan? New York external appeals are available to residents regardless of where their insurance plan is based. The key is New York residency, not plan location.

From Our Advocates In our experience helping patients with iron chelation appeals, the most successful cases include comprehensive transfusion logs showing the progression of iron overload, specific documentation of why preferred chelators failed or caused intolerance, and a detailed ANC monitoring plan that addresses Ferriprox's unique safety requirements.
