When to Start Your Renewal Process

Your Fintepla renewal process should begin 60 days before your current prior authorization expires. Aetna CVS Health typically approves Fintepla for 12-month periods, but some approvals may be shorter depending on your specific plan and medical history.

Early renewal triggers:

  • Authorization expires within 90 days
  • Significant changes in seizure frequency (better or worse)
  • New cardiac findings on echocardiogram
  • Dosage adjustments needed
  • Plan formulary changes announced
Tip: Set a calendar reminder for 75 days before expiration to gather documentation early.

Signs you should start immediately:

  • Recent denial letter received
  • Pharmacy reporting coverage issues
  • Changes to your Aetna plan effective date
  • New cardiac symptoms or echo abnormalities

Required Evidence for Renewal

Successful Fintepla renewal with Aetna CVS Health requires clear documentation of ongoing clinical benefit and safety monitoring compliance.

Seizure Response Documentation

Essential seizure frequency evidence:

  • Baseline seizure logs from before Fintepla initiation
  • Current seizure diaries showing frequency over the past 6 months
  • Quantitative comparison (e.g., "Seizures reduced from 15/month to 4/month")
  • Seizure type documentation (convulsive vs. non-convulsive)
  • Quality of life improvements noted by caregivers
Note: Aetna typically requires at least a 25% reduction in seizure frequency for renewal approval.

Clinical Progress Notes

Your neurologist should provide recent chart notes documenting:

  • Current diagnosis (Dravet syndrome or Lennox-Gastaut syndrome)
  • Response to Fintepla therapy
  • Current dosing and adherence
  • Side effects and tolerability
  • Plans for continued treatment

REMS Monitoring Documentation

Fintepla requires ongoing cardiac monitoring through the REMS program due to risks of valvular heart disease and pulmonary arterial hypertension.

Required Cardiac Monitoring

Baseline Original pre-treatment echo For comparison with current results
Post-discontinuation Echo 3-6 months after stopping If applicable to your case

Critical cardiac documentation:

  • Recent echocardiogram report (within 6 months)
  • Cardiac risk assessment by prescriber

The key is quantitative data—exact seizure counts before and after starting treatment, not just general statements about improvement."

FAQ

How long does Aetna CVS Health take to process Fintepla renewals? Standard renewals typically take 30-45 days. Expedited reviews for urgent medical needs are completed within 72 hours.

What if my echocardiogram shows new abnormalities? Your prescriber must document a risk-benefit analysis. Minor changes may not prevent renewal if seizure control benefits outweigh cardiac risks.

Can I request a longer authorization period? Most Fintepla authorizations are approved for 12 months. Some plans may approve shorter periods initially, with longer renewals after demonstrating response.

What happens if I miss my renewal deadline? Contact your prescriber immediately to request an expedited appeal and emergency medication supply. Don't stop Fintepla without medical supervision.

Does step therapy apply to Fintepla renewals? If you're already on Fintepla with documented response, step therapy typically doesn't apply to renewals. New requirements may apply if you switch plans.
