Read the Denial: Decoding UnitedHealthcare's Reasons

When UnitedHealthcare denies Galafold coverage, the denial letter will specify the exact reason. Common denial codes include:

Medical Necessity Denials:

  • Missing amenable GLA variant documentation
  • Lack of confirmed Fabry disease diagnosis
  • Severe renal impairment (eGFR <30)
  • Insufficient prior therapy documentation

Administrative Denials:

  • Incomplete prior authorization form
  • Missing prescriber information
  • Wrong pharmacy benefit vs. medical benefit submission
Tip: Look for the specific denial reason code in your letter. This determines which documents you'll need for your appeal.

Your denial letter will also include critical deadlines. UnitedHealthcare typically allows 180 days for internal appeals, but verify this timeline in your specific denial notice.

Fixable Causes: Common Documentation Issues

Many Galafold denials can be overturned by addressing documentation gaps:

Missing Genetic Testing Results

The most common denial reason is lack of amenable variant proof. You need:

  • Complete GLA gene sequencing report
  • Confirmation the variant is listed in the Galafold Amenability Table
  • If unlisted, HEK assay results proving amenability

Incomplete Medical Records

Ensure your submission includes:

  • Fabry disease diagnosis with ICD-10 code E75.21
  • Current kidney function (eGFR ≥30 required)
  • Specialist evaluation (genetics, nephrology, or metabolic specialist)
  • Treatment history and response to any prior therapies

Coding Mismatches

Galafold is a pharmacy benefit drug (NDC-billed), not a medical benefit. Ensure your provider submits through OptumRx, not medical claims.

First-Level Appeal: Building Your Case

What to Include in Your Appeal Letter

Header Information:

  • Patient name, DOB, member ID
  • Policy number and group number
  • Prescriber name and NPI
  • Date of original denial

Clinical Justification:

  1. Confirmed Diagnosis: "Patient has confirmed Fabry disease (ICD-10: E75.21) based on [clinical symptoms/family history/enzyme testing]"
  2. Amenable Variant: "Genetic testing confirms [specific variant] which is amenable to migalastat per FDA-approved amenability criteria"
  3. Medical Necessity: "Galafold is medically necessary to prevent progressive organ damage characteristic of Fabry disease"
  4. Contraindications to Alternatives: If applicable, document why enzyme replacement therapy isn't suitable

Required Attachments

  • Complete genetic testing report
  • Specialist consultation notes
  • Recent lab results (kidney function, cardiac assessment)
  • Prior therapy records if applicable
  • Published guidelines supporting Galafold use

Submit appeals through the UnitedHealthcare provider portal or mail to the address on your denial letter.

Peer-to-Peer Review: Direct Discussion Strategy

If your initial PA is denied, request a peer-to-peer review before filing a formal appeal. This allows your prescriber to speak directly with a UnitedHealthcare medical director.

Scheduling Your Peer-to-Peer

Call the number on your denial letter or use the provider portal to request a peer-to-peer discussion. These typically occur within 1-2 business days.

Key Talking Points for Your Doctor

  1. FDA Approval Context: Emphasize Galafold's specific FDA indication for amenable variants
  2. Disease Progression: Highlight the progressive, irreversible nature of Fabry disease
  3. Variant-Specific Therapy: Explain why only amenable variants respond to migalastat
  4. Alternative Limitations: Discuss any contraindications to enzyme replacement therapy
  5. Published Evidence: Reference clinical trials and guidelines supporting Galafold use
From Our Advocates: We've seen peer-to-peer reviews succeed when doctors clearly explain that Galafold works through a unique mechanism—it's not interchangeable with enzyme replacement therapy but specifically designed for patients with amenable mutations. Having the genetic report and amenability documentation readily available during the call significantly improves approval odds.

Michigan External Review: Your Final Option

If UnitedHealthcare upholds their denial after internal appeals, Michigan residents can request an external review through the Department of Insurance and Financial Services (DIFS).

Timeline and Eligibility

  • Deadline: 127 days after receiving your final internal denial
  • Process: Independent medical experts review your case
  • Timeline: Standard reviews completed within 60 days; expedited reviews within 72 hours

How to File

  1. Complete the DIFS External Review Request form
  2. Attach your denial letters and supporting medical documentation
  3. Submit online at difs.state.mi.us or mail to DIFS

Required Documentation

  • All denial letters from UnitedHealthcare
  • Complete medical records supporting medical necessity
  • Genetic testing results
  • Physician statement of medical necessity
  • Any additional clinical evidence

For expedited review (if delay would jeopardize health), include a physician letter stating why immediate approval is critical.

Medical Necessity Letter Template

[Date]
[UnitedHealthcare Medical Director]
[Address from denial letter]

RE: Appeal for Coverage of Galafold (migalastat)
Member: [Name], DOB: [Date], ID: [Member ID]

Dear Medical Director,

I am writing to appeal the denial of coverage for Galafold (migalastat) for my patient with confirmed Fabry disease.

CLINICAL BACKGROUND:
Patient has confirmed Fabry disease (ICD-10: E75.21) based on:
- [Clinical presentation/family history]
- Genetic testing confirming [specific GLA variant]
- [Enzyme activity results if applicable]

AMENABLE VARIANT CONFIRMATION:
Genetic analysis confirms the patient carries the [specific variant] GLA mutation, which is [listed in the FDA-approved Galafold Amenability Table/confirmed amenable by HEK assay]. This variant responds specifically to migalastat therapy.

MEDICAL NECESSITY:
Galafold is medically necessary because:
1. Patient has progressive Fabry disease requiring treatment
2. The specific GLA variant is amenable to migalastat
3. Current kidney function (eGFR: [value]) supports safe use
4. [Any contraindications to alternatives]

SUPPORTING EVIDENCE:
[Attach: genetic report, specialist notes, lab results, published guidelines]

Based on the clinical evidence and FDA-approved indication, I respectfully request approval of Galafold for this patient.

Sincerely,
[Physician name, credentials, license number]
