Medical Necessity Requirements

To meet Blue Cross Blue Shield's medical necessity criteria for Opfolda, you must satisfy all of the following requirements:

Diagnosis and Patient Eligibility

  • Confirmed late-onset Pompe disease (LOPD) via genetic testing or enzyme assay
  • Adult patient (≥18 years old)
  • Body weight ≥40 kg (88 pounds)

Enzyme Replacement Therapy History

Your medical records must document:

  • Current or previous treatment with standard enzyme replacement therapy (alglucosidase alfa or avalglucosidase alfa)
  • Evidence of inadequate response after at least 12 months of ERT treatment
  • Objective measures showing disease progression, such as:
    • Declining 6-minute walk test results
    • Worsening forced vital capacity (FVC)
    • Persistent muscle weakness despite treatment

Combination Therapy Requirement

  • Opfolda must be prescribed with Pombiliti (cipaglucosidase alfa)
  • Cannot be approved as monotherapy
  • Weight-based dosing: 195 mg (40-<50 kg) or 260 mg (≥50 kg) every other week

Specialist Involvement

Prescriptions must come from or be coordinated with a qualified specialist, typically:

  • Neuromuscular specialist
  • Geneticist
  • Metabolic disorder specialist
  • Pulmonologist with rare disease experience
Clinician Corner: When documenting medical necessity, include specific functional assessments with dates, prior ERT regimens with start/stop dates and reasons for inadequacy, and objective measures like spirometry results showing FVC decline despite treatment.

Step Therapy and Exceptions

Blue Cross Blue Shield typically requires patients to try and fail standard enzyme replacement therapy before approving Opfolda. However, you can request a step therapy exception if:

  • Previous ERT caused severe adverse reactions requiring discontinuation
  • Medical contraindications prevent use of standard ERT
  • Clinical evidence shows standard ERT is inappropriate for your specific case

Documenting Step Therapy Failure

Your specialist should provide:

  • Complete medication history with specific agents, doses, and duration
  • Clinical notes documenting lack of improvement or disease progression
  • Objective measures (lab values, functional tests) showing inadequate response
  • Any adverse reactions or intolerances experienced

Prior Authorization Process

  4. Await Determination (30 days): Standard processing time; expedited review available for urgent cases (72 hours).
  5. Coordinate Specialty Pharmacy (If approved): Work with Blue Cross specialty pharmacy network for medication delivery.
  6. Schedule Infusion Coordination (Patient/Clinic): Coordinate Opfolda timing with Pombiliti infusions.
  7. Monitor and Document (Ongoing): Track clinical response for future reauthorization requests.

Common Denial Reasons and Solutions

Denial Reason How to Overturn
"Not medically necessary" Provide objective measures showing ERT failure and disease progression
"Experimental/investigational" Reference FDA approval and clinical trial data from ATB200-03 study
"Missing step therapy" Document previous ERT trials with specific agents, doses, and outcomes
"Incorrect dosing/timing" Confirm weight-based dosing aligned with Pombiliti infusion schedule
"Monotherapy request" Ensure prescription includes both Opfolda and Pombiliti combination
From Our Advocates: "We've seen several New York patients initially denied for 'lack of medical necessity' successfully overturn denials by providing detailed functional assessments showing decline despite 18+ months of standard ERT. The key is objective, measurable evidence of treatment failure."
