Why New York State Rules Matter

New York has some of the strongest patient protection laws in the country, and they directly impact how Humana must handle your Galafold (migalastat) request. Unlike many states, New York limits step therapy requirements and guarantees fast external appeals when insurance companies deny coverage.

Key New York advantages:

  • Maximum 72-hour response time for standard prior authorizations
  • 24-hour turnaround for urgent specialty drug requests
  • Step therapy limited to trying only two drugs before accessing your prescribed medication
  • Automatic approval if Humana doesn't respond within required timeframes
  • Independent external review through the Department of Financial Services

These protections apply to all Humana Medicare Advantage plans in New York, giving you stronger rights than patients in many other states.

Humana's Coverage Requirements for Galafold

Galafold (migalastat) is a specialty medication that requires careful documentation due to its high cost—approximately $360,000-$400,000 per year—and specific genetic requirements.

Essential documentation for approval:

  1. Confirmed Fabry disease diagnosis with ICD-10 code
  2. Genetic testing results showing amenable GLA mutation from the FDA-approved list
  3. Specialist evaluation from genetics, nephrology, or metabolic medicine
  4. Treatment history if other Fabry therapies were tried
  5. Kidney function tests (eGFR must be ≥30 mL/min/1.73m²)
Clinician Corner: Your medical necessity letter should specifically reference the patient's GLA mutation and cite the FDA label's amenable mutation table. Include why enzyme replacement therapies (Fabrazyme, Elfabrio) are inappropriate—whether due to access issues, antibody development, or patient preference for oral therapy.

Step Therapy Protections in New York

New York's step therapy reform laws, effective January 2026, provide significant protections for rare disease patients like those with Fabry disease.

Your rights under New York law:

  • Maximum 2 drugs: Humana cannot require you to try more than two medications before approving Galafold
  • 30-day limit: Step therapy requirements cannot exceed 30 days or clinical guideline recommendations
  • No repeat trials: If you've tried and failed a drug in the past year, you can't be forced to try it again
  • Stability protection: If you're stable on Galafold, Humana cannot force you to switch

Medical exception criteria:

  • Previous drug was ineffective or caused adverse reactions
  • Required drug is not FDA-approved for Fabry disease
  • Delay would cause harm or irreversible consequences
  • Patient has comorbid conditions that make alternatives inappropriate

When requesting a step therapy exception, your doctor should provide written attestation addressing these criteria. Counterforce Health helps patients and providers navigate these complex requirements by analyzing denial letters and crafting targeted appeals that address payer-specific policies.

Appeals Process: Internal to External Review

Understanding the appeals timeline is crucial because missing deadlines can mean starting over or losing coverage opportunities.

Humana Internal Appeals (First Level):

  • Deadline: 65 days from denial notice
  • Standard review: 30 days for decision
  • Expedited review: 72 hours (24 hours for urgent drug denials)

New York External Review (After Internal Denial):

  • Deadline: 4 months from final internal denial
  • Standard review: 30 days for decision
  • Expedited review: 3 days (72 hours) for urgent cases
  • Cost: Free for members
  • Authority: New York Department of Financial Services
Note: New York's external review decisions are binding on Humana, and the state has a track record of overturning denials for rare disease treatments when proper documentation is provided.

"Not medically necessary" Demonstrate Fabry progression and treatment need Clinical notes + specialist evaluation
"Experimental/investigational" Cite FDA approval and clinical guidelines FDA label + treatment guidelines
"Severe kidney disease" Show eGFR ≥30 or document why still appropriate Recent lab values + nephrologist note

When to Escalate: External Review Process

If Humana's internal appeals process doesn't result in approval, New York's external review system provides an independent path to coverage.

Filing an external appeal:

  1. Download forms from the NY DFS website
  2. Gather all documentation from your internal appeals
  3. Request expedited review if your doctor certifies that waiting would jeopardize your health
  4. Submit within 4 months of receiving final internal denial

What happens next:

  • Independent medical expert reviews your case
  • Decision is binding on Humana
  • If approved, Humana must cover treatment and refund any appeal fees
  • You can also pursue a State Fair Hearing simultaneously
From Our Advocates: We've seen external appeals succeed for Galafold when patients provide comprehensive genetic testing documentation and clear evidence that enzyme replacement therapies aren't suitable. The key is addressing the specific clinical criteria that led to the original denial, not just restating the medical necessity.

Costs and Patient Support Options

Even with insurance approval, Galafold can have significant out-of-pocket costs. Several programs can help reduce your financial burden:

Manufacturer Support:

Foundation Grants:

  • National Organization for Rare Disorders (NORD) patient assistance
  • HealthWell Foundation specialty drug grants
  • Patient Access Network (PAN) Foundation support

State Programs:

  • New York State Medicaid for eligible residents
