What Drives Orfadin (nitisinone) Costs with Humana

Orfadin's high cost stems from its orphan drug status as the only FDA-approved treatment for hereditary tyrosinemia type 1 (HT-1). Understanding Humana's benefit design helps you navigate coverage successfully.

Formulary Tier Placement

Orfadin typically appears on Tier 5 (specialty drugs) in Humana Medicare Advantage Part D plans, requiring the highest copays or coinsurance. Humana uses a 5-tier formulary structure where specialty medications like Orfadin face prior authorization requirements and may require specialty pharmacy dispensing.

Prior Authorization Requirements

All Humana plans require prior authorization for Orfadin, focusing on:

  • Confirmed HT-1 diagnosis via biochemical testing
  • Medical necessity documentation
  • Dietary management plan coordination
  • Prescriber attestation of clinical rationale
Note: Generic nitisinone became available in 2023 and may have better formulary placement, but bioequivalence monitoring is essential during any switch.

Does step therapy apply to Orfadin? Step therapy is rarely required for orphan drugs like Orfadin when prescribed for FDA-approved indications like HT-1, as there are no therapeutic alternatives.

What if I've tried treatments outside Texas? Prior therapy trials from other states count toward PA requirements when properly documented. Include all medical records and failure/intolerance documentation.

Clinician Corner: Medical Necessity Letter Essentials

Key Components for Approval:

  • Diagnosis: Confirmed HT-1 with biochemical evidence (elevated succinylacetone)
  • Clinical rationale: FDA-approved indication, no therapeutic alternatives
  • Prior treatments: Document any previous therapies and outcomes
  • Monitoring plan: Lab schedule for succinylacetone and liver function
  • Dosing justification: Weight-based calculations per FDA labeling

Guideline References:

From our advocates: "We've seen the strongest approvals when prescribers include specific lab values in their medical necessity letters rather than just stating 'elevated levels.' Quantifying succinylacetone at 15.2 μmol/L (normal <0.5) provides concrete evidence that reviewers can easily assess against diagnostic criteria."
