Step 1: Set Your Coverage Goal

Working with your neurologist is essential for Mavenclad approval. This isn't just about getting a prescription—it's about building a compelling case that meets Aetna CVS Health's specific criteria while leveraging New York's strong patient protection laws.

Your partnership goal: Create documentation that shows Mavenclad is medically necessary for your relapsing MS, that you've tried other treatments without success, and that you meet all safety requirements.

Note: Mavenclad is only approved for adults with relapsing forms of MS. It's not covered for clinically isolated syndrome or primary progressive MS, so confirming your exact diagnosis is crucial.

What approval requires:

  • Confirmed relapsing MS diagnosis (relapsing-remitting or active secondary progressive)
  • Documentation of at least two failed or poorly tolerated disease-modifying therapies
  • Recent lab work showing adequate lymphocyte counts
  • Absence of contraindications (active malignancy, current infections, pregnancy)
  • Appropriate contraception plan if you're of childbearing potential

Step 2: Prepare for Your Doctor Visit

Come to your appointment with a clear timeline of your MS journey. Your neurologist needs specific details to craft a strong medical necessity letter.

Symptom timeline to prepare:

  • Date of initial MS diagnosis
  • Type of MS (relapsing-remitting vs. active secondary progressive)
  • Recent relapse dates and symptoms
  • Current disability level and functional limitations
  • MRI findings showing disease activity

Treatment history checklist:

  • Names and dates of all previous disease-modifying therapies
  • Specific reasons each treatment was discontinued (lack of efficacy, side effects, contraindications)
  • Duration of each treatment trial
  • Any hospitalizations or serious relapses while on treatment

Current status notes:

  • Recent symptoms affecting daily activities
  • Work or school limitations due to MS
  • Physical therapy or rehabilitation needs
  • Other medications you're taking
From our advocates: Patients who bring a typed, chronological summary of their treatment history save significant appointment time and ensure nothing important gets overlooked. This documentation often becomes the foundation of a successful prior authorization.

Step 3: Build Your Evidence Kit

Your neurologist will need comprehensive documentation to support the Mavenclad request. Help them gather everything in advance.

Essential lab work and imaging:

  • Complete blood count (CBC) with differential within 3 months
  • Comprehensive metabolic panel
  • Liver function tests
  • Recent brain and/or spinal cord MRI
  • Pregnancy test if applicable

Clinical documentation needed:

  • Complete medical records from your MS specialist
  • Hospital records from any MS-related admissions
  • Documentation of previous DMT trials and outcomes
  • Current neurological exam findings
  • Functional status assessments

Published guidelines support: The FDA prescribing information confirms Mavenclad is indicated for relapsing forms of MS in adults who have had an inadequate response to, or are unable to tolerate, two alternative disease-modifying therapies.

Step 4: Medical Necessity Letter Structure

Your neurologist's medical necessity letter is the cornerstone of your prior authorization. Here's what it must include:

Patient identification:

  • Full name, date of birth, Aetna member ID
  • Prescriber name, credentials, NPI number
  • Date of letter and direct signature

Diagnosis section:

  • Specific MS diagnosis with ICD-10 code G35
  • Date of initial diagnosis
  • Current disease activity and recent MRI findings

Clinical rationale:

  • Clear explanation of why Mavenclad is appropriate
  • Reference to FDA-approved indications
  • Discussion of patient-specific factors

Prior therapy documentation:

  • Detailed list of previous DMTs with dates
  • Specific reasons for discontinuation of each therapy
  • Duration of treatment trials
  • Clinical outcomes and adverse events

Safety considerations:

  • Recent laboratory values (lymphocyte count, liver function)
  • Contraception plan if applicable
  • Screening for contraindications completed

Supporting evidence:

  • References to published guidelines
  • Clinical studies supporting Mavenclad use
  • Professional society recommendations

Step 5: Support Your Provider's Peer-to-Peer Review

If Aetna initially denies coverage, they may offer a peer-to-peer review where your neurologist discusses the case directly with an Aetna medical director.

How to help your provider prepare:

  • Offer flexible scheduling for the peer-to-peer call
  • Provide a concise case summary highlighting key points
  • Ensure all supporting documents are readily available

Key talking points for your neurologist:

  • Emphasis on failed prior therapies and specific reasons for failure
  • Current disease activity requiring more effective treatment
  • Mavenclad's unique mechanism of action and dosing schedule
  • Patient's ability to comply with monitoring requirements

Sample peer-to-peer script elements: "This patient has relapsing-remitting MS with continued disease activity despite trials of [specific DMTs]. They experienced [specific adverse events/lack of efficacy] with previous treatments. Mavenclad offers a unique oral treatment option with proven efficacy in reducing relapse rates and disability progression."

Step 6: Document Everything After Your Visit

Keep detailed records of all interactions with Aetna CVS Health and your healthcare providers.

What to save:

  • All prior authorization submissions and confirmations
  • Denial letters with specific reasons cited
  • Appeal submissions and acknowledgments
  • Phone call logs with dates, times, and representative names
  • Fax confirmations and delivery receipts

Portal messaging strategy:

  • Use your patient portal to request copies of all clinical notes
  • Ask for written summaries of treatment plans
  • Request copies of any letters sent to insurance companies

Communication with your provider's office:

  • Establish a primary contact person for insurance issues
  • Ask for regular updates on prior authorization status
  • Request copies of all insurance correspondence

Step 7: Practice Respectful Persistence

Insurance approvals often require multiple touchpoints. Stay organized and professional in all interactions.

Follow-up cadence:

  • Week 1: Confirm prior authorization submission
  • Week 2: Check status if no response received
  • Week 3: Request expedited review if appropriate
  • Week 4: Prepare for potential appeal if denied

Escalation pathway:

  • Start with customer service representatives
  • Request supervisor review for complex issues
  • Ask for case manager assignment for ongoing problems
  • Contact member advocacy if available through your plan

Professional communication tips:

  • Always get representative names and reference numbers
  • Confirm next steps and timelines in writing
  • Maintain calm, factual tone even when frustrated
  • Document all interactions for potential appeals
