How to Use This Guide

This decision tree helps you determine if Tysabri (natalizumab) coverage through Aetna (CVS Health) is within reach in New Jersey. Work through each section to identify your eligibility status, then follow the specific action steps for your situation.

Start here: Review the eligibility triage below. Based on your answers, you'll fall into one of four categories with tailored next steps. If you're already dealing with a denial, skip to the appeals section.

Eligibility Triage: Do You Qualify?

Answer these questions to determine your coverage likelihood:

Diagnosis & Specialist Care

  • ✅ Relapsing MS confirmed? (RRMS, CIS, or active SPMS with ICD-10 code G35)
  • ✅ Neurologist involved? (Required for Aetna authorization)
  • ✅ Recent disease activity? (MRI evidence of new/enhancing lesions or clinical relapses within past year)

Safety Requirements

  • ✅ JCV antibody test completed? (Mandatory for PML risk assessment)
  • ✅ Baseline brain MRI within 3 months? (Required to rule out existing PML)
  • ✅ TOUCH program enrollment possible? (Federal requirement for all Tysabri patients/prescribers)

Treatment History

  • ✅ Prior DMT trials documented? (Evidence of inadequate response, though strict step therapy not required for MS)
  • ✅ No contraindications? (Not currently on immunosuppressants or TNF inhibitors)

Your Result:

  • 4-6 checkmarks: Likely eligible - proceed to document checklist
  • 2-3 checkmarks: Possibly eligible - additional testing/documentation needed
  • 0-1 checkmarks: Not yet eligible - explore alternatives and preparation steps

If "Likely Eligible": Document Checklist

Required Documentation for Aetna PA Submission

Document Purpose Where to Get It Timeline

If "Possibly Eligible": Tests to Request

Missing Pieces to Address

Need specialist confirmation? Request referral to MS specialist if currently seeing general neurologist. Aetna requires specialist involvement for Tysabri authorization.

Recent MRI needed? Schedule brain MRI with gadolinium if your last scan is over 6 months old. Aetna reviews for evidence of active disease.

JCV status unknown? Ask your neurologist to order anti-JCV antibody testing. Results help determine your PML risk category and monitoring schedule.

Treatment history unclear? Gather documentation of previous DMT trials, including:

  • Medication names and dates
  • Reason for discontinuation (lack of efficacy vs. intolerance)
  • Clinical evidence of inadequate response (relapses, MRI progression)

Timeline to Reapply

Most missing documentation can be obtained within 2-4 weeks. Schedule follow-up with your neurologist to review completed requirements and resubmit your PA request.

If "Not Yet": Alternatives to Consider

Coverage-Building Strategies

Establish treatment pattern: If you haven't tried other DMTs, consider documenting trials of preferred formulary options (typically interferons, glatiramer acetate, or newer oral agents) with your neurologist.

Gather stronger evidence: Work with your care team to document disease progression through:

  • Serial MRI comparisons showing new lesions
  • Functional assessments (EDSS scores)
  • Quality of life impact documentation

Exception request preparation: Even without meeting standard criteria, you may qualify for a formulary exception if your neurologist can demonstrate medical necessity based on:

  • Contraindications to preferred agents
  • Previous severe adverse reactions
  • Unique clinical circumstances

If Denied: Your Appeal Options

Internal Appeals (Start Here)

First-level internal appeal:

  • Who files: Your neurologist (preferred) or you
  • Deadline: 90 days from denial notice
  • Form: Aetna Provider Appeal Form
  • Timeline: 30 calendar days for decision

Peer-to-peer review: Request specialist-to-specialist discussion during internal appeal. Often resolves complex cases faster than standard review.

New Jersey External Review (IHCAP)

If internal appeals fail, New Jersey's Independent Health Care Appeals Program provides binding external review.

Eligibility: Fully-insured Aetna plans (not self-funded employer plans) File through: Maximus IHCAP Portal Deadline: 4 months from final internal denial Cost: Free to you (insurer pays all fees)

FAQ: Your Top Questions Answered

Q: How long does Aetna PA review take in New Jersey? A: Standard review: 30-45 days. Expedited review (if urgent): 72 hours. Submit early to avoid treatment gaps.

From Our Advocates

"We've seen Aetna denials overturned when providers include a detailed timeline showing exactly how long each prior DMT was tried and why it failed. One New Jersey patient's appeal succeeded after their neurologist documented not just 'inadequate response' but specific relapse dates and MRI progression while on previous therapies. The key was painting a clear picture of disease activity despite treatment."
