Start Here: Verify Your Plan & Requirements

Before submitting any paperwork, confirm your specific Blue Cross Blue Shield of Michigan coverage:

Step 1: Identify Your Plan Type

  • Commercial/Employer Plans: Use BCBSM or Blue Care Network prior authorization process
  • Medicare Advantage: Follow Medicare Part D coverage determination rules (72-hour standard, 24-hour expedited)
  • Blue Cross Complete (Medicaid): Separate PA process through Medicaid managed care

Step 2: Check Current Coverage Status Call the member services number on your insurance card and ask:

  • Is Daybue (trofinetide) on the formulary?
  • What tier is it assigned to?
  • Is prior authorization required?
  • Are there quantity limits or step therapy requirements?
  • Is AnovoRx Specialty Pharmacy recognized as an in-network provider for limited-distribution drugs?
Note: Daybue is exclusively dispensed through AnovoRx Specialty Pharmacy in the U.S., not through BCBSM's standard Walgreens specialty network.

Prior Authorization Forms & Documentation

Required Clinical Documentation

For Rett Syndrome Diagnosis Confirmation:

  • Documented diagnosis of Rett syndrome with ICD-10 code
  • Genetic testing results showing pathogenic MECP2, FOXG1, or CDKL5 variant (when available)
  • Patient age ≥2 years (FDA-approved age range)
  • Current weight for weight-based dosing calculation

Specialist Requirements:

  • Prescriber must be or involve a neurologist, geneticist, or developmental pediatrician
  • Clinical notes describing Rett syndrome manifestations and current functional status
  • Documentation of disease severity and treatment goals

Medical Necessity Letter Checklist

Your specialist should include:

  1. Confirmed Rett syndrome diagnosis with supporting clinical features
  2. FDA-approved indication (Rett syndrome in patients ≥2 years)
  3. Weight-based dosing rationale (oral solution 200 mg/mL, twice daily)
  4. Monitoring plan for common side effects (diarrhea, vomiting, weight loss)
  5. Expected clinical benefit and how response will be measured
  6. Supporting evidence from FDA labeling and clinical guidelines
Clinician Corner: BCBSM's genetic testing policy requires that Rett syndrome testing be performed "to confirm a diagnosis of Rett syndrome in a child with developmental delay and signs/symptoms of Rett syndrome, but there is uncertainty in the clinical diagnosis." Include this language when genetic testing supports the Daybue request.

FAQ

How long does BCBSM prior authorization take for Daybue? Standard PA decisions are typically made within 5-7 business days. Medicare Advantage plans must decide within 72 hours (24 hours if expedited).

What if Daybue is non-formulary on my plan? Submit a formulary exception request with your PA. Include documentation that no formulary alternatives exist for Rett syndrome, as Daybue is the first and only FDA-approved therapy.

Can I request an expedited review? Yes, if your physician certifies that waiting for standard timelines would seriously jeopardize your health. Include a detailed urgency letter with your request.

Does step therapy apply to Daybue? Unlikely, since Daybue is the only FDA-approved therapy for Rett syndrome. If step therapy is required, document that no therapeutic alternatives exist.

What happens if I move to another Blue Cross plan? Coverage criteria vary between Blue Cross plans. You may need to resubmit PA documentation when changing plans, even within the Blue Cross system.

How often do I need to renew prior authorization? Typically annually, though this varies by plan. Renewal requires documenting continued medical necessity and clinical benefit.
