Step-by-Step: Fastest Path to Approval

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

Call the CVS Caremark number on your insurance card or log into your Aetna member portal. Ask specifically about:

  • Your formulary tier for Mavenclad
  • Your deductible amount and whether it applies
  • Your specialty medication coinsurance percentage
  • Whether you need to use CVS Specialty Pharmacy

2. Gather Required Documentation (Neurologist - Days 1-3)

Your neurologist needs to collect:

  • Prior DMT history: Names, dates, durations (≥3-6 months each), specific reasons for discontinuation
  • Recent labs: CBC with differential, comprehensive metabolic panel, liver function tests (within 3 months)
  • MRI evidence: Recent scans showing disease activity
  • Diagnosis confirmation: ICD-10 code G35 for relapsing MS

3. Submit Prior Authorization (Neurologist - Day 4)

Submit via Availity portal or fax to 1-866-249-6155 with:

  • Medical necessity letter detailing MS diagnosis and prior treatment failures
  • Lab results showing lymphocyte count ≥800 cells/μL
  • MRI reports demonstrating disease activity
  • Complete prior therapy documentation

Expected timeline: Standard review 72 hours; expedited review 24 hours for urgent cases.

4. Track Your Request (Patient/Clinic - Days 5-7)

Monitor status through Aetna provider portal or call CVS Caremark. If no response within 72 hours, contact Aetna's precertification team at 1-855-582-2025.

5. If Approved: Coordinate with CVS Specialty (Days 8-10)

CVS Specialty will contact you within 24-48 hours to arrange delivery. They'll also process any copay assistance programs you're enrolled in.

6. If Denied: Request Peer-to-Peer Review (Immediate)

Your neurologist can request a peer-to-peer discussion with an Aetna medical director. This often resolves denials based on incomplete information.

7. File Internal Appeal if Necessary (Within 180 days)

Submit additional evidence addressing the specific denial reason. In Illinois, you have strong rights to external review if the internal appeal fails.

Understanding Your Costs and Assistance Options

Insurance Coverage Breakdown

Mavenclad sits on Aetna's specialty tier, meaning you'll typically pay:

  • Deductible: Full cost until met (varies by plan)
  • Coinsurance: 20-40% of the drug cost after deductible
  • Total 2-year course: Often exceeds $100,000 before insurance

Manufacturer Assistance Programs

MS LifeLines Co-Pay Assistance Program can reduce your out-of-pocket costs to as low as $0 per prescription for commercially insured patients. Call 1-877-447-3243 (Mon-Fri 8am-8pm ET, Sat 9am-5pm ET) to enroll.

Eligibility requirements:

  • Commercial insurance (not Medicare/Medicaid)
  • U.S. or Puerto Rico residency
  • Valid Mavenclad prescription

Foundation Grants

Patient Access Network (PAN) Foundation MS Fund provides up to $5,400 per year in copay assistance for eligible patients. Apply at panfoundation.org with income documentation.

Free Drug Programs

If you're uninsured or underinsured, the MS LifeLines Patient Assistance Program may provide Mavenclad at no cost. Income limits apply, and your healthcare provider must fax a Prescription and Service Request Form to 866-227-3243.

From our advocates: We've seen patients successfully combine manufacturer copay assistance with foundation grants to eliminate their out-of-pocket costs entirely. The key is applying to multiple programs simultaneously since approval timelines vary, and some programs have limited funding that runs out during the year.

Common Denial Reasons and How to Fix Them

Denial Reason How to Overturn
Incomplete prior therapy documentation Provide detailed records: drug names, exact dates, durations, doses, and specific reasons for discontinuation (relapses, new lesions, intolerance)
Lymphocyte count too low Retest when count recovers to ≥800 cells/μL; include trending lab values showing improvement
Non-qualified prescriber Transfer prescription to neurologist or MS specialist; include their credentials and specialty certification
Step therapy not satisfied Document ≥2 prior DMT failures with clinical evidence (MRI progression, EDSS scores, relapse frequency)
"Not medically necessary" Request peer-to-peer review; provide current MS treatment guidelines supporting Mavenclad use
