How to Use This Decision Tree

This guide walks you through Aetna CVS Health's requirements for Opfolda (miglustat) coverage in Washington state. Work through each section in order—the eligibility triage will tell you exactly where you stand and what documents you need to gather.

Note: Opfolda is only approved in combination with Pombiliti (cipaglucosidase alfa-atga). Never request Opfolda alone—this will result in automatic denial.

Eligibility Triage: Do You Qualify?

Step 1: Basic Requirements ✓

Answer YES to all of these:

  • Confirmed diagnosis of late-onset Pompe disease (LOPD) with genetic or enzyme testing
  • Age 18 years or older
  • Weight over 40 kg (88 lbs)
  • Prescribed by or consulting with a specialist (neurologist, geneticist, metabolic specialist)

Step 2: Prior Therapy History ✓

  • You've tried enzyme replacement therapy (ERT) like Lumizyme or Nexviazyme for at least 12 months
  • Your doctor has documented that ERT didn't provide adequate improvement
  • You have records showing functional decline or lack of benefit (6-minute walk test, breathing tests, muscle strength)

Step 3: Current Treatment Plan ✓

  • Your doctor is prescribing both Opfolda AND Pombiliti together
  • You have a monitoring plan for regular assessments

Results:

  • All boxes checked = "Likely Eligible" → Go to Document Checklist
  • Missing 1-2 items = "Possibly Eligible" → See Tests to Request
  • Missing 3+ items = "Not Yet" → Review Alternatives

If "Likely Eligible": Document Checklist

Your doctor needs to submit these documents to Aetna's prior authorization system:

Required Documentation

Document Type What to Include Where to Get It
Diagnosis Confirmation GAA enzyme activity results, genetic testing showing GAA mutations, ICD-10 codes Lab reports, genetic counselor
ERT History Drug names, dates, doses, duration (≥12 months), clinical outcomes, reason for inadequacy Previous prescribing doctors, pharmacy records
Functional Assessments 6-minute walk distance, forced vital capacity (FVC), muscle strength tests, before/during ERT Pulmonary function lab, physical therapy
Specialist Evaluation Consultation notes, treatment rationale, monitoring plan Neurologist, geneticist, or metabolic specialist
Combination Therapy Prescriptions for both Opfolda and Pombiliti with dosing schedule Prescribing physician

Submission Process

  1. Submit at least 2 weeks before you need to start therapy
  2. Use Aetna's Availity portal or fax to specialty pharmacy prior authorization: 1-888-267-3277
  3. Include all documents in one submission to avoid delays
  4. Request expedited review if medically urgent (72-hour decision)

Standard review takes 5-7 business days. Verify current submission requirements as policies update annually.

If "Possibly Eligible": Tests to Request

Missing some requirements? Here's what to ask your doctor for:

Need Diagnosis Confirmation?

  • GAA enzyme activity test (blood or dried blood spot)
  • Genetic testing for GAA gene mutations
  • Muscle biopsy (if enzyme/genetic tests inconclusive)

Need ERT Documentation?

  • Request records from all previous doctors who prescribed Lumizyme, Nexviazyme, or other ERTs
  • Pharmacy records showing fill dates and quantities
  • Functional test results from before, during, and after ERT trials

Timeline to Re-apply

  • Allow 4-6 weeks to gather missing documentation
  • Schedule specialist consultation if you haven't seen one recently
  • Coordinate testing so all results are available before resubmission

If "Not Yet": Alternatives and Exception Requests

Don't meet standard criteria? You still have options:

Alternative Treatments to Discuss

  • Nexviazyme (avalglucosidase alfa) - newer ERT that may work better
  • Lumizyme (alglucosidase alfa) - standard ERT if not previously tried
  • Supportive care - respiratory support, physical therapy, nutrition

Exception Request Strategy

Even if you don't meet typical criteria, Aetna may approve Opfolda through their formulary exception process if your doctor can demonstrate:

  • Contraindications to standard ERTs (allergic reactions, infusion reactions)
  • Rapid disease progression despite current therapy
  • Compelling medical literature supporting earlier use
From our advocates: We've seen cases where patients who hadn't quite reached the 12-month ERT requirement got approved when their doctor documented rapid functional decline and provided peer-reviewed studies showing Opfolda's mechanism could address their specific situation. The key was submitting a comprehensive medical necessity letter that addressed each denial criterion individually.

If Denied: Washington Appeal Process

Washington has strong consumer protections for insurance appeals. Here's your step-by-step path:

Level 1: Internal Appeal (Required First)

Timeline: File within 180 days of denial Process: Submit written appeal to Aetna with additional documentation Decision: 30-45 days (72 hours if expedited)

Level 2: External Review (Independent)

Who decides: Certified Independent Review Organization (IRO) assigned by Washington Insurance Commissioner Timeline: File within 180 days of final internal denial Process: Submit request through your insurer or directly to Washington Office of Insurance Commissioner Decision: 30 days standard, 72 hours expedited Outcome: Binding on Aetna if overturned

FAQ: Aetna CVS Health Coverage in Washington

How long does Aetna prior authorization take for Opfolda? Standard review is 5-7 business days. Expedited (urgent) reviews are completed within 72 hours. Submit at least 2 weeks before you need to start treatment.

What if Opfolda is not on Aetna's formulary? Request a formulary exception through CVS Caremark. Your doctor must provide clinical justification for why Opfolda is medically necessary despite not being preferred.

Can I get an expedited appeal in Washington? Yes. If delay could jeopardize your health, request expedited review at each level. Internal appeals: 72 hours. External review: 72 hours. Your doctor must certify the urgency.

Does step therapy apply if I tried ERT in another state? Yes. ERT trial documentation from any state counts toward Washington requirements, as long as you have complete medical records showing the trial duration and outcomes.

What if my employer plan is self-funded? Self-funded ERISA plans may not follow Washington state appeal rules. However, many voluntarily use external review. Contact the U.S. Department of Labor for ERISA plan appeals guidance.

How much does Opfolda cost without insurance? U.S. pricing isn't publicly disclosed at the individual drug level (it's bundled with Pombiliti). Contact Amicus Assist for patient assistance program information and pricing details.

Can I switch from another ERT to Opfolda/Pombiliti? Yes, if you meet the inadequate response criteria. Your doctor should document why the switch is medically necessary and stop the previous ERT two weeks before starting the new combination.

What happens if the external review upholds the denial? The IRO decision is binding. You may contact the Washington Insurance Commissioner for guidance on additional options or consider legal consultation for complex cases.
