Appeals Playbook for Florida

Florida residents have strong appeal rights under state and federal law. Here's your roadmap:

Internal Appeal (Level 1)

  • Timeline: File within 180 days of denial
  • Decision: 30 days standard, 72 hours expedited
  • How to file: Aetna member portal or written request
  • Required: Denial letter, additional clinical evidence, prescriber support letter

Peer-to-Peer Review

  • When: Complex cases or after initial denial
  • Who: Neurologist speaks directly with Aetna medical director
  • Preparation: Clinical timeline, current guidelines, patient-specific factors
  • Outcome: Often resolves coverage disputes efficiently

External Review (Binding)

  • Timeline: File within 4 months of final internal denial
  • Decision: 30-45 days standard, 72 hours expedited
  • Process: Independent medical reviewer through Florida Department of Financial Services
  • Cost: Free to patient
  • Authority: Decision is binding on Aetna
From Our Advocates: We've seen peer-to-peer reviews succeed when neurologists clearly explain why alternatives failed and how Tysabri fits current MS treatment guidelines. The key is having all clinical documentation organized before the call—denial reversals often happen when medical directors can see the complete treatment timeline and patient response patterns.

Medical Necessity Letter Essentials

When drafting appeals or formulary exceptions, include these critical elements:

Clinical Foundation

  • Diagnosis: Specific MS type with ICD-10 codes
  • Disease activity: Relapse frequency, MRI progression, disability measures
  • Prior treatments: Specific agents tried, duration, outcomes, reasons for discontinuation
  • Contraindications: Why alternatives aren't suitable

Risk Assessment

  • JCV antibody status: Test results and monitoring plan
  • MRI surveillance: Baseline and follow-up imaging schedule
  • REMS compliance: TOUCH program adherence confirmation

Supporting Evidence

  • FDA labeling: On-label use confirmation
  • Clinical guidelines: AAN, ECTRIMS, or other society recommendations
  • Peer-reviewed literature: Relevant efficacy and safety data

Costs and Patient Support

Tysabri's high cost makes financial assistance crucial:

Manufacturer Support

Foundation Assistance

  • National MS Society: Financial assistance programs
  • Patient Access Network: Copay support for specialty drugs
  • HealthWell Foundation: MS-specific grants

State Programs

Florida residents may qualify for additional support through state pharmaceutical assistance programs (verify current availability with Florida Department of Health).

Frequently Asked Questions

How long does Aetna prior authorization take for Tysabri in Florida? Standard decisions arrive within 30-45 days. Expedited requests (when delay could harm health) are decided within 72 hours. Track status through the Aetna provider or member portal.

What if Tysabri isn't on my Aetna formulary? Request a formulary exception with medical necessity documentation. Your prescriber must explain why formulary alternatives are ineffective or contraindicated for your specific case.

Can I get an expedited appeal in Florida? Yes, if your physician certifies that delay would jeopardize your health. Expedited appeals are decided within 72 hours, and you can request expedited external review simultaneously.

Does step therapy apply if I've tried DMTs outside Florida? Yes, prior therapy documentation from any location counts. Provide complete records showing specific agents tried, duration, and outcomes regardless of where treatment occurred.

What happens if my TOUCH enrollment lapses? Tysabri cannot be dispensed without active TOUCH enrollment. Re-enrollment is required, which may delay treatment. Maintain continuous enrollment to avoid coverage interruptions.

How much does external review cost in Florida? External review through Florida Department of Financial Services is free to patients. You only pay for gathering and submitting required documentation.

Can I appeal while continuing current treatment? Continue current MS therapy during appeals unless contraindicated. Don't stop effective treatment while pursuing Tysabri coverage—gaps in DMT therapy can worsen MS outcomes.

What if Aetna requires a different specialty pharmacy? Aetna typically requires CVS Specialty for Tysabri. If you prefer a different pharmacy, request an exception with documentation of medical necessity or access issues.
