Submit PA through OptumRx provider portal with specialist evaluation, genetic/enzyme results, and clinical evidence of kidney, heart, or brain symptoms. If denied, Pennsylvania's new external review program has a 50% overturn rate. First step today: Contact your prescribing specialist to gather diagnostic documentation and submit the PA request through UnitedHealthcare's provider portal.

Policy Overview: How UnitedHealthcare Covers Elfabrio

UnitedHealthcare covers Elfabrio (pegunigalsidase alfa-iwxj) across all plan types—HMO, PPO, and Medicare Advantage—but requires prior authorization through OptumRx. The drug is typically placed on specialty tiers requiring higher copays or coinsurance.

Where to Find Official Policies:

Note: Pennsylvania Medicaid managed by UnitedHealthcare may have additional state-specific requirements. Check with your plan administrator for Medicaid-specific policies.

FDA Indication Requirements

Elfabrio is FDA-approved for enzyme replacement therapy in adults with confirmed Fabry disease. UnitedHealthcare generally covers FDA-approved indications when medical necessity criteria are met.

Key Requirements:

  • Patient must be 18 years or older (FDA label indication)
  • Confirmed Fabry disease diagnosis
  • Clinical evidence of organ involvement
  • No concurrent use with migalastat (Galafold)

Step Therapy & Medical Exceptions

While UnitedHealthcare doesn't typically require step therapy for Fabry disease treatments due to the limited options, they may prefer certain enzyme replacement therapies based on formulary positioning.

Medical Exception Pathways:

  • Contraindication to alternatives: Document allergy or adverse reaction to agalsidase-beta (Fabrazyme)
  • Treatment failure: Previous ERT inadequate response with clinical documentation
  • Non-amenable variants: For patients ineligible for migalastat therapy
Tip: If switching from another ERT, document the clinical rationale (e.g., infusion reactions, lack of efficacy) with supporting lab values or symptom progression.

Quantity and Frequency Limits

Standard Dosing: 1 mg/kg actual body weight every 2 weeks via IV infusion

Quantity Calculations:

  • Supplied as 20 mg/10 mL vials (2 mg/mL concentrate)
  • Example: 70 kg patient = 70 mg dose = 3.5 vials per infusion
  • Monthly quantity: ~7 vials (accounting for weight-based dosing)

Renewal Requirements:

  • Initial authorization: Typically 6-12 months
  • Reauthorization requires clinical response documentation
  • Ongoing monitoring labs (eGFR, cardiac function, biomarkers)

Required Diagnostics

UnitedHealthcare requires specific diagnostic evidence to establish medical necessity:

Diagnostic Requirements Table

Test Type Male Patients Female Patients Documentation Needed
Enzyme Testing α-Gal A activity <5% of mean May be normal; not diagnostic Lab report with reference ranges
Genetic Testing GLA gene sequencing if enzyme 5-10% Primary diagnostic method Pathogenic variant identification
Biomarkers Lyso-Gb3 levels Lyso-Gb3 levels Elevated levels support diagnosis
Timing Within 12 months of PA request Within 12 months of PA request Recent results preferred

Additional Clinical Evidence:

  • Kidney function: eGFR, proteinuria, creatinine
  • Cardiac assessment: Echo, EKG, cardiac MRI if indicated
  • Neurological: Brain MRI for stroke/white matter lesions
  • Pain assessment: Neuropathic pain documentation

Site of Care & Specialty Pharmacy

Approved Administration Sites:

  • Hospital outpatient infusion centers
  • Physician office infusion suites
  • Specialty infusion clinics

Specialty Pharmacy Requirements:

  • Must use UnitedHealthcare-contracted specialty pharmacy
  • OptumRx Specialty Pharmacy is the preferred provider
  • Coordination with infusion site for delivery and storage

Buy-and-Bill Considerations:

  • Some providers may purchase and bill directly
  • Requires J-code billing (currently J3590 - unclassified drug)
  • Prior authorization still required regardless of billing method

Evidence Supporting Medical Necessity

When building your case for Elfabrio coverage, include evidence from these authoritative sources:

Clinical Guidelines:

  • FDA Prescribing Information
  • International Fabry Disease Consortium recommendations
  • American Society of Nephrology guidelines for genetic kidney diseases

Peer-Reviewed Literature:

  • Phase 3 clinical trial data (BRIGHT study)
  • Comparative effectiveness studies vs. other ERTs
  • Real-world evidence of clinical outcomes

Patient-Specific Factors:

  • Disease progression markers
  • Quality of life impact
  • Previous treatment responses or intolerances
Clinician Corner: Include 2-3 key citations in your medical necessity letter, focusing on evidence that directly supports Elfabrio's efficacy for your patient's specific manifestations (renal, cardiac, or neurological).

Sample Medical Necessity Narrative

"This 45-year-old male patient has genetically confirmed Fabry disease (GLA mutation c.427G>A) with progressive chronic kidney disease (eGFR 35 mL/min/1.73m²) and left ventricular hypertrophy. Previous treatment with agalsidase-beta was discontinued due to severe infusion reactions requiring emergency intervention. Elfabrio (pegunigalsidase alfa-iwxj) 1 mg/kg IV every 2 weeks is medically necessary to provide enzyme replacement therapy and prevent further organ deterioration. The patient meets all FDA-approved indication criteria and has no contraindications to therapy. Clinical monitoring will include renal function, cardiac assessment, and biomarker trends per established protocols."

Edge Cases & Special Situations

Pediatric Patients:

  • FDA approval is for adults only
  • Off-label use requires additional justification
  • Consider compassionate use or clinical trial options

Pregnancy:

  • Limited safety data available
  • Risk-benefit analysis required
  • Coordinate with maternal-fetal medicine specialist

Switching from Other ERTs:

  • Document clinical rationale for switch
  • Include washout period considerations
  • Monitor for immunogenicity changes

Renal Transplant Recipients:

  • May still require ERT for other organ manifestations
  • Coordinate with transplant team
  • Monitor for drug interactions with immunosuppressants

Appeals Process in Pennsylvania

Pennsylvania launched its Independent External Review Program in January 2024, giving patients powerful new appeal rights with a 50% success rate.

Internal Appeals (Required First Step)

  • Deadline: 180 days from denial letter
  • Timeline: 30 days for standard review, 72 hours for urgent
  • Submit to: UnitedHealthcare member portal, mail, or fax
  • Required: Original denial letter, additional clinical documentation, updated medical necessity letter

Pennsylvania External Review

  • Deadline: 4 months after final internal denial
  • Timeline: 45 days standard, 72 hours expedited
  • Submit: Online at pa.gov or by mail/fax
  • Success Rate: Approximately 50% of appeals are overturned
  • Binding: UnitedHealthcare must provide immediate coverage if approved
From our advocates: We've seen Pennsylvania's external review program work particularly well for rare disease treatments like Elfabrio. The independent physicians reviewing these cases often understand the limited treatment options and urgent medical need better than internal insurance reviewers. Success often comes down to having complete diagnostic documentation and clear evidence of organ involvement.

Common Denial Reasons & Solutions

Denial Reason Solution Documentation Needed
Insufficient diagnostic evidence Submit complete genetic testing and enzyme assay results Lab reports, genetic counselor summary
Not medically necessary Provide specialist evaluation with organ involvement evidence Cardiology, nephrology, or neurology consultation
Alternative therapy available Document contraindications or failures with other ERTs Previous treatment records, adverse event documentation
Quantity/dosing issues Justify weight-based dosing with current weight Recent clinic visit notes with documented weight
Site of care restrictions Confirm infusion center is in-network Provider credentialing verification

Appeal Strategy Tips:

  • Address each specific denial reason point-by-point
  • Include peer-reviewed literature supporting Elfabrio use
  • Provide timeline of disease progression without treatment
