Who Should Use This Checklist

This comprehensive checklist is designed for patients with Dravet syndrome or Lennox-Gastaut syndrome (LGS) who need Fintepla (fenfluramine) coverage through Aetna (CVS Health) in Texas. You'll also find this helpful if you've received a denial and need to prepare an appeal.

Expected outcome: When all requirements are met, Aetna typically approves Fintepla for initial 12-month periods. The process takes 2-4 weeks for standard review, or up to 72 hours for expedited cases involving urgent seizure control needs.

Member & Plan Basics

✓ Verify Active Aetna Coverage

  • Confirm your Aetna member ID and plan type (commercial, Medicare Advantage, or Medicaid)
  • Check if your plan uses CVS Caremark for specialty medications
  • Verify your deductible status and specialty drug copay tier

✓ Prior Authorization Requirements

Aetna requires prior authorization for Fintepla across all plan types in Texas. The medication is typically placed on a non-formulary tier, requiring medical exception documentation.

Key Texas-specific note: Texas law requires all state-regulated health plans to provide internal appeals within 180 days and external review options through Independent Review Organizations (IROs).

Clinical Criteria Requirements

✓ FDA-Approved Indications

Fintepla is approved for seizures associated with:

  • Dravet syndrome (ICD-10: G40.83) in patients 2 years and older
  • Lennox-Gastaut syndrome (ICD-10: G40.81) in patients 2 years and older

✓ Step Therapy Documentation

Aetna requires documentation of failure with at least 2 standard antiseizure medications before approving Fintepla. Required documentation includes:

  • Medication names and dosages tried
  • Duration of each trial (minimum 4-6 weeks at therapeutic doses)
  • Specific reasons for discontinuation (inefficacy, intolerance, or contraindications)
  • Seizure frequency before and during trials

Common step therapy medications for Dravet/LGS include:

  • Clobazam
  • Valproate
  • Stiripentol
  • Cannabidiol (Epidiolex)
  • Rufinamide
  • Topiramate
  • Lamotrigine

✓ Age and Dosing Requirements

  • Patient must be 2 years of age or older
  • Starting dose: ≤0.4 mg/kg/day
  • Maximum dose: 21 mg/day (children), 26 mg/day (adults)

Coding & Documentation Requirements

✓ ICD-10 Diagnosis Codes

Condition ICD-10 Code Required Documentation
Dravet syndrome G40.83 Genetic testing confirmation, EEG findings
Lennox-Gastaut syndrome G40.81 EEG showing generalized slow spike-wave, clinical criteria

✓ HCPCS/NDC Information

  • HCPCS Code: J1443 (injection, fenfluramine, 1 mg)
  • NDC: Verify current NDC with CVS Specialty Pharmacy
  • Units: Based on prescribed dose and patient weight

REMS Program Enrollment

The FDA requires all patients, prescribers, and pharmacies to enroll in the Fintepla REMS program due to risks of cardiac valve problems and pulmonary hypertension.

✓ Prescriber Requirements

  • Complete REMS training and assessment
  • Submit Prescriber Enrollment Form
  • Obtain baseline echocardiogram before treatment
  • Order follow-up echocardiograms every 6 months

✓ Patient Requirements

  • Complete Patient Enrollment Form with prescriber signature
  • Undergo baseline echocardiogram showing no valvular heart disease or pulmonary hypertension
  • Commit to ongoing cardiac monitoring every 6 months

✓ Echocardiogram Documentation

Critical for approval: Submit baseline echo results showing:

  • No evidence of valvular heart disease
  • No signs of pulmonary hypertension
  • Normal cardiac function parameters
From our advocates: We've seen cases where families spent weeks waiting for approval, only to discover the baseline echo results weren't properly submitted with the REMS enrollment. Always confirm your prescriber has uploaded the echo report to the REMS portal before submitting your Aetna prior authorization.

Submission Process

  • Patient Enrollment Form (completed)
  • Prescriber Enrollment Form (completed)
  • Baseline echocardiogram results

Step Therapy Documentation:

  2. Specific diagnosis with ICD-10 code
  3. Detailed seizure history and current frequency
  4. Complete list of failed antiseizure medications
  5. Clinical rationale for Fintepla
  6. Expected treatment goals and monitoring plan

CVS Specialty Pharmacy Transfer

Most Aetna plans require Fintepla to be dispensed through CVS Specialty Pharmacy as a REMS-certified specialty pharmacy.

✓ Initiate Transfer Process

  1. Prescriber submits prescription to CVS Specialty (call 1-800-237-2767 or electronic submission)
  2. Patient completes intake with CVS clinical team
  3. CVS verifies prior authorization and REMS status
  4. Schedule delivery (typically 1-2 business days after approval)

✓ Ongoing Management

  • Enroll in Easy Refill after 2-3 fills for automated notifications
  • Coordinate 6-month echocardiogram scheduling with CVS clinical team
  • Update insurance information promptly to avoid delays
