Step-by-Step: Fastest Path to Approval

1. Verify Your Coverage (Patient Action - 1 Day)

Log into your Aetna member portal or call the pharmacy number on your ID card. Confirm Mavenclad's formulary tier and whether CVS Specialty Pharmacy handles fulfillment. Commercial plans differ from Medicaid/Medicare requirements.

2. Gather Required Documentation (Clinic Action - 3-5 Days)

Your neurologist needs:

  • Complete blood count with differential (lymphocytes ≥800 cells/μL)
  • Liver function tests and comprehensive metabolic panel
  • Documentation of ≥2 prior DMT failures with specific dates, doses, and reasons for discontinuation
  • Current MRI reports showing MS activity
  • Pregnancy test for women of childbearing potential

3. Submit Prior Authorization (Provider Action - Same Day)

Submit via Availity portal (fastest) or fax to 1-866-249-6155. Include the Aetna PA form and medical necessity letter addressing all criteria.

4. Track Your Request (Patient/Provider - Ongoing)

Standard decisions: 72 hours. Expedited (mark as urgent if health risk): 24 hours. You'll receive notification by phone or mail.

5. If Approved: Coordinate Fulfillment (Patient Action - 1-2 Days)

CVS Specialty Pharmacy will contact you for delivery coordination. Verify your copay and explore manufacturer assistance if needed.

6. If Denied: File Internal Appeal (Patient/Provider - Within 180 Days)

Request detailed denial reason and submit additional evidence. Consider requesting a peer-to-peer review between your neurologist and Aetna's medical reviewer.

7. External Review if Needed (Patient Action - Within 4 Months)

File with Florida's Department of Financial Services if internal appeal fails. This independent review is binding and free to patients.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Evidence
Inadequate step therapy Submit detailed DMT history with failure documentation Pharmacy records, clinical notes showing breakthrough relapses or MRI progression
Missing lab work Provide current CBC with differential Lab report dated within 3 months showing lymphocytes ≥800 cells/μL
Prescriber not qualified Confirm neurologist credentials Board certification verification
Safety concerns unaddressed Submit comprehensive screening results Infection panel, malignancy history, contraception plan
Diagnosis not confirmed Provide complete MS diagnostic workup MRI reports, ICD-10 code G35 documentation
From our advocates: We've seen denials reversed when providers include specific failure details—not just "patient failed interferon" but "patient experienced 3 relapses and 5 new T2 lesions over 8 months on interferon beta-1a despite good adherence, documented by pharmacy refill records."

Frequently Asked Questions

How long does Aetna CVS Health prior authorization take in Florida? Standard PA decisions: 72 hours. Expedited reviews (for urgent medical needs): 24 hours. Submit early to avoid treatment delays.

What if Mavenclad is non-formulary on my plan? Request a formulary exception through the same PA process. Emphasize medical necessity and document why formulary alternatives are inappropriate.

Can I request an expedited appeal? Yes, if standard review timelines would seriously jeopardize your health. Mark requests as urgent and provide supporting clinical documentation.

Does step therapy apply if I failed DMTs outside Florida? Yes, documented failures from any state count toward step therapy requirements. Gather complete records from all previous providers.

What happens if my lymphocyte count drops below 800? Treatment with Mavenclad year 2 must be delayed until lymphocytes recover. This may require updated PA submission with current lab values.

How much does Mavenclad cost with Aetna coverage? Costs vary by plan tier and deductible. The 2-year course commonly costs six figures before insurance. Check your specific copay and explore manufacturer assistance programs.

Can I appeal to an independent reviewer? Yes, Florida offers binding external review through independent medical experts after internal appeals are exhausted. File within 4 months of final denial.

What if Aetna requires additional DMT trials? Document specific contraindications, intolerances, or medical reasons why additional trials would be inappropriate. Request peer-to-peer review for complex cases.
