Policy Overview: How UnitedHealthcare Evaluates Opfolda

UnitedHealthcare manages Opfolda prior authorization through OptumRx for pharmacy benefits and medical benefits review for infusion coordination. The insurer applies consistent criteria across HMO, PPO, and Medicare Advantage plans, with some variations for Medicaid managed care.

Plan Types Covered:

  • Commercial (employer-sponsored)
  • Individual/ACA marketplace plans
  • Medicare Advantage
  • Medicaid managed care (varies by state contract)

You can find official policies at uhcprovider.com/policies under "Commercial Medical & Drug Policies" and "Enzyme Replacement Therapy."

Note: New Jersey residents with UnitedHealthcare have robust appeal rights through the state's Independent Health Care Appeals Program (IHCAP), which provides binding external review at no cost to patients.

Indication Requirements

FDA-Approved Use: Opfolda is approved only for use with Pombiliti (cipaglucosidase alfa) in adults with late-onset Pompe disease weighing at least 40 kg who are not improving on current enzyme replacement therapy.

Key Clinical Criteria:

  • Confirmed LOPD diagnosis via genetic testing (GAA gene mutations) or enzymatic assay
  • Age ≥18 years
  • Weight ≥40 kg (documented within 30 days)
  • Active, inadequate response to current ERT for ≥24 months
  • ICD-10 code documentation (E74.02 - Pompe disease)

Critical Restriction: Opfolda has no therapeutic effect when used alone. UnitedHealthcare will deny any request for monotherapy, as this contradicts FDA labeling and clinical evidence.

Step Therapy & Exceptions

Unlike many specialty medications, Opfolda doesn't follow traditional step therapy since it's only indicated for patients already failing standard ERT. However, UnitedHealthcare requires documentation of inadequate response to at least one of these therapies:

Required Prior Therapies:

  • Lumizyme (alglucosidase alfa)
  • Nexviazyme (avalglucosidase alfa)

Medical Exception Pathways: If a patient cannot tolerate standard ERTs due to severe infusion reactions or contraindications, document:

  • Specific adverse reactions with dates
  • Severity requiring discontinuation
  • Specialist recommendations for alternative therapy

Submit exception requests through the UnitedHealthcare Provider Portal with supporting clinical notes from the treating specialist.

Required Diagnostics & Documentation

Essential Lab Work (within 12 months):

  • Acid alpha-glucosidase enzyme activity levels
  • Creatine kinase (CK) levels
  • Genetic testing results (if enzyme assay inconclusive)

Functional Assessments:

  • Forced vital capacity (FVC) measurements
  • 6-minute walk test (6MWT) results
  • Muscle strength assessments

Documentation Tips:

  • Include numerical values with reference ranges
  • Show trends over time (≥12 months preferred)
  • Obtain measurements from certified pulmonary function labs
  • Ensure all tests are performed by qualified specialists
Tip: Request copies of all test results for your records. UnitedHealthcare may ask for additional documentation during review.

Site of Care & Specialty Pharmacy

Administration Requirements:

  • Opfolda: Oral capsules taken 1 hour before Pombiliti infusion
  • Pombiliti: IV infusion every other week at certified infusion center

Specialty Pharmacy Coordination: UnitedHealthcare requires specialty pharmacy dispensing for Opfolda through OptumRx or approved network providers. Contact OptumRx at 800-310-6826 for enrollment.

Weight-Based Dosing:

  • 40-<50 kg: 195 mg (3 capsules) every other week
  • ≥50 kg: 260 mg (4 capsules) every other week

Timing coordination between oral Opfolda and IV Pombiliti is critical for therapeutic effectiveness and coverage approval.

Evidence to Support Medical Necessity

Clinical Guidelines to Reference:

  • FDA prescribing information for both medications
  • Pompe disease treatment guidelines from the Association for Creatine Deficiencies
  • Specialist society recommendations for ERT failure management

Peer-Reviewed Evidence: Include citations from the pivotal PROPEL study demonstrating improved outcomes with combination therapy versus ERT alone. Reference specific endpoints like FVC improvement and 6MWT distance.

Documentation Framework:

  1. Problem statement: LOPD with documented ERT failure
  2. Prior treatments: Specific ERTs tried, duration, outcomes
  3. Clinical rationale: Why combination therapy is appropriate
  4. Monitoring plan: How response will be assessed
  5. Dosing justification: Weight-based dosing per FDA label

Common Denial Reasons & Fixes

Denial Reason How to Overturn Required Documents
Insufficient ERT failure evidence Resubmit with objective data FVC trends, 6MWT results, CK levels over 12+ months
No active Pombiliti PA Submit both PAs together Confirmation of UHC medical benefit approval
Inadequate medical necessity Strengthen clinical rationale Specialist letter with specific decline metrics
Weight not documented Provide recent measurement Clinical note with weight ≥40 kg within 30 days
Monotherapy request Clarify combination therapy Prescription for both medications with timing

Quick Fixes:

  • Missing documentation: Fax additional records to PA review team within 24 hours
  • Weak rationale: Request peer-to-peer review with specialist
  • Timing issues: Clarify administration schedule in supplemental letter

Appeals Playbook for New Jersey

Internal Appeals (UnitedHealthcare)

Level 1 - Standard Reconsideration

External Review (New Jersey IHCAP)

After exhausting internal appeals, New Jersey residents can access free, binding external review through the Independent Health Care Appeals Program.

Key Details:

  • Contact: 1-888-393-1062
  • Deadline: 4 months (120 days) from final internal denial
  • Cost: Free to patients
  • Decision: Binding on UnitedHealthcare if overturned

How to File:

  1. Call IHCAP hotline for application packet
  2. Submit completed forms with all medical records
  3. Include detailed provider letter explaining medical necessity
  4. Wait for independent physician panel review

Success Rates: External reviews favor patients in approximately 50% of cases nationwide, with higher success rates for well-documented rare disease cases.

From our advocates: We've seen several Pompe disease appeals succeed at the external review level when providers included detailed ERT failure timelines with specific functional decline metrics. The key is showing objective deterioration despite optimal standard therapy, not just subjective symptoms.

FAQ

How long does UnitedHealthcare prior authorization take for Opfolda in New Jersey? Standard review takes 7-14 business days. Expedited review (for urgent cases) takes 24-72 hours. Submit complete documentation to avoid delays.

What if Opfolda is non-formulary on my plan? Non-formulary medications can still be covered with prior authorization and medical necessity documentation. The combination with Pombiliti for LOPD often qualifies for coverage despite formulary status.

Can I request an expedited appeal in New Jersey? Yes, both UnitedHealthcare internal appeals and New Jersey IHCAP offer expedited review for urgent medical situations where delays could cause serious harm.

Does step therapy apply if I failed ERT outside New Jersey? Medical records from any state are accepted. Document specific ERT trials, duration, and failure evidence regardless of where treatment occurred.

What happens if IHCAP overturns UnitedHealthcare's denial? The decision is binding. UnitedHealthcare must provide coverage and cannot appeal the IHCAP decision. This is mandated by New Jersey statute.

How much does Opfolda cost without insurance? U.S. pricing is disclosed at the combination therapy level with Pombiliti. Contact Amicus Assist for patient assistance programs and copay support options.
