Policy Overview: How Aetna Handles Tysabri

Aetna CVS Health covers Tysabri (natalizumab) across all plan types in Pennsylvania—HMO, PPO, and Medicare plans—but prior authorization is mandatory. The drug is typically classified as a specialty medication requiring coordination through CVS Specialty Pharmacy.

Plan-Specific Considerations

Commercial Plans: Standard 30-45 day review timeline with step therapy requirements that may vary by employer group.

Medicare Part D: Stricter timelines (72 hours for expedited appeals) with additional CMS oversight of coverage decisions.

Medicaid Plans: Follow Pennsylvania Medicaid guidelines with additional state-specific documentation requirements.

Note: Self-funded employer plans may have different criteria than standard Aetna policies. Always verify your specific plan's coverage rules.

Medical Necessity Requirements

Aetna's medical policy for Tysabri requires specific clinical criteria to establish medical necessity:

For Multiple Sclerosis

  • Diagnosis: Relapsing forms of MS or clinically isolated syndrome
  • Disease Activity: Evidence of ongoing relapses or MRI progression
  • Specialist Oversight: Prescribed by or in consultation with a neurologist
  • Safety Monitoring: JCV antibody testing and ongoing PML risk assessment

For Crohn's Disease

  • Severity: Moderate-to-severe active disease
  • Prior Failures: Inadequate response to conventional therapies and TNF-alpha inhibitors
  • Specialist Care: Gastroenterologist involvement required
  • Monitoring: CD-TOUCH program enrollment with 3-month review milestones

The Aetna medical policy outlines these requirements in detail and is updated regularly.


Step Therapy and Exceptions

Step therapy typically applies for Tysabri, meaning you may need to try and fail other MS treatments first. However, medical exceptions are available with proper documentation.

Common Step Therapy Requirements

  1. First-line agents: Interferons, glatiramer acetate, or oral medications
  2. Documentation needed: Treatment dates, doses, duration, and reason for discontinuation
  3. Failure criteria: Lack of efficacy, intolerance, or contraindications

Medical Exception Pathways

  • Contraindications: Document medical reasons why preferred agents cannot be used
  • Prior failures: Include records from other insurance plans or time periods
  • Clinical urgency: Rapidly progressing disease requiring immediate intervention
Tip: Keep detailed records of all MS treatments, including those tried under previous insurance plans. This documentation can support exception requests.

Required Diagnostics and Documentation
