Plan Types & Coverage Requirements

Your UnitedHealthcare plan type in Michigan determines whether you need referrals to see Pompe disease specialists and how prior authorization works.

Commercial Plans (Employer/ACA Individual):

  • HMO/HMO-POS: Requires PCP referral to see endocrinologists or neurologists for Pompe disease management
  • PPO: No referral needed; you can self-refer to in-network specialists
  • EPO: Must use in-network providers; some EPO plans require referrals (check your specific plan—some Michigan EPO plans like "UHC Bronze Essential (No Referrals)" explicitly allow direct specialist access)

Medicare Advantage (Starting 2026):

  • HMO/HMO-POS: Will require PCP referrals for most specialists, including endocrinology and neurology (claims won't be denied for missing referrals until May 1, 2026)
  • PPO: No referral requirements
  • Michigan Integrated DSNP (H2247-005): Exempt from new referral requirements
Tip: Check your insurance card for "Referrals required" or "No referrals" language, or log into your UnitedHealthcare member portal to verify your exact plan requirements.

Formulary Status & Tier Placement

Pombiliti isn't explicitly listed in UnitedHealthcare's 2025 formulary updates, but as a high-cost specialty enzyme replacement therapy, it typically falls under Tier 4 (highest-cost) placement with strict utilization controls.

Coverage Element Pombiliti Status What This Means
Prior Authorization Required Must be approved before dispensing
Step Therapy Likely May need to try Lumizyme first
Quantity Limits Possible Dosing restrictions based on weight
Specialty Pharmacy Required Must use designated specialty pharmacy

Formulary Verification Steps:

  1. Log into your UnitedHealthcare member portal
  2. Search "Pombiliti" or "cipaglucosidase alfa" in your plan's drug list
  3. Call the pharmacy number on your ID card for real-time status
  4. Ask specifically about tier placement and any restrictions

Prior Authorization Criteria

UnitedHealthcare requires comprehensive documentation to approve Pombiliti for late-onset Pompe disease. The criteria are strict and evidence-based.

Required Documentation:

  • Diagnosis Confirmation: GAA enzyme activity <40% of lab normal mean OR molecular genetic testing showing GAA gene mutations
  • Weight Requirement: Current medical records showing patient weighs ≥40 kg
  • Clinical Symptoms: Evidence of respiratory distress, skeletal muscle weakness, or cardiac involvement
  • ERT Failure: Documentation that patient is not improving on current enzyme replacement therapy (Lumizyme or Nexviazyme)
  • Combination Therapy: Prescription for Opfolda (miglustat) as required companion drug
  • Specialist Involvement: Metabolic specialist or geneticist consultation
Note: Authorization is typically granted for up to 12 months initially, with reauthorization requiring evidence of clinical benefit.

For patients and clinicians navigating complex insurance approvals like this, Counterforce Health offers a specialized platform that helps turn insurance denials into targeted, evidence-backed appeals.

Common Denial Reasons & Solutions

Denial Reason Required Fix Documentation to Submit
Missing ERT failure documentation Prove inadequate response to prior therapy Functional decline data, symptom progression notes, treatment timeline
Weight requirement not met Confirm patient weighs ≥40 kg Recent clinic visit notes with documented weight
Unconfirmed Pompe diagnosis Provide definitive diagnostic evidence GAA enzyme results <40% normal OR genetic testing report
No Opfolda combination Submit joint prescription Prescription for both Pombiliti and Opfolda together
Lack of specialist involvement Get appropriate consultation Metabolic specialist or geneticist evaluation and recommendation
Step therapy not completed Document prior ERT trial Records of Lumizyme or Nexviazyme treatment with outcomes

Clinician Corner: Medical Necessity Letter Essentials

Cost-Share Considerations

Pombiliti's list price approaches $650,000 annually for the combination therapy, making cost-sharing a significant concern even with insurance coverage.

Potential Cost-Sharing Scenarios:

  • Tier 4 Copay: Often $150-500+ per month
  • Coinsurance: Typically 25-50% of drug cost until out-of-pocket maximum
  • Deductible: May need to meet medical or pharmacy deductible first

Financial Assistance Options:

  • Amicus Assist Program: Manufacturer patient support program (verify eligibility at Amicus Therapeutics website)
  • Foundation Grants: Organizations like HealthWell Foundation may offer copay assistance for rare diseases
  • State Programs: Michigan may have additional assistance for rare disease treatments
Note: This information is educational only. Actual costs depend on your specific plan design, deductible status, and benefit year timing.

When to Escalate

Consider escalating beyond standard appeals when:

Immediate Health Risk:

  • Disease progression threatens respiratory function
  • Functional decline is rapid or severe
  • Current ERT is causing serious adverse reactions

Process Failures:

  • UnitedHealthcare misses review deadlines
  • Denial reasons don't match submitted documentation
  • Appeals process isn't followed correctly

Escalation Options:

  • Michigan Department of Insurance and Financial Services: File complaint about insurer practices
  • State Representative/Senator: Contact for assistance with insurance issues
  • Patient Advocacy Organizations: Pompe disease support groups may offer guidance

Frequently Asked Questions

How long does UnitedHealthcare prior authorization take for Pombiliti in Michigan? Standard prior authorization review takes up to 15 business days. Expedited reviews for urgent medical situations are completed within 72 hours when supported by physician attestation of medical urgency.

What if Pombiliti is non-formulary on my UnitedHealthcare plan? Non-formulary drugs can still be covered through the exception process. Submit a formulary exception request with strong medical necessity documentation explaining why preferred alternatives are inadequate.

Can I request an expedited appeal if my prior authorization is denied? Yes, if your treating physician attests that delay could seriously jeopardize your health or ability to regain function. Both UnitedHealthcare internal appeals and Michigan DIFS external reviews offer expedited timelines of 72 hours.

Does step therapy apply if I've already failed other ERTs outside Michigan? Previous ERT failures from other states should count toward step therapy requirements. Include complete medical records documenting the treatment timeline and outcomes when submitting your prior authorization.

What happens if I move from Michigan to another state while on Pombiliti? Coverage may change based on your new state's regulations and available UnitedHealthcare plans. Contact member services before relocating to understand how your coverage will be affected.

How do I find a Pompe disease specialist in my UnitedHealthcare network? Use the UnitedHealthcare provider directory and search for neurology (neuromuscular), endocrinology, or medical genetics specialists. Cross-reference with academic medical centers that have Pompe disease expertise.

What if my employer plan is self-funded (ERISA)? Self-funded plans follow federal ERISA rules rather than Michigan state insurance laws. External appeals go through a federal process rather than Michigan DIFS. Check your plan documents or contact HR to confirm your plan type.

Can my doctor submit the prior authorization on my behalf? Yes, healthcare providers can submit prior authorizations and appeals for patients. Most submissions go through the UnitedHealthcare Provider Portal or electronic prior authorization systems like CoverMyMeds.

From our advocates: "We've seen Pombiliti approvals succeed when providers clearly document the specific functional decline on previous ERT—like decreased walking distance or worsening pulmonary function tests—rather than just stating 'not improving.' Quantified data makes the medical necessity much clearer to reviewers."
