California Appeals Process

California residents have strong appeal rights through the Department of Managed Health Care (DMHC). If Aetna denies your vigabatrin renewal:

Internal Appeal Process

  1. File grievance with Aetna within 180 days of denial
  2. Provide additional evidence including updated medical records
  3. Request peer-to-peer review between your neurologist and Aetna's medical director
  4. Await decision within 30 days (expedited: 72 hours for urgent cases)

Independent Medical Review (IMR)

If internal appeal fails, California's IMR process offers:

  • 60-68% success rate for medically necessary treatments
  • No cost to patients - DMHC covers all review expenses
  • Binding decisions - Aetna must implement favorable outcomes
  • 45-day timeline for standard reviews, 7 days for urgent cases

To request IMR: Call DMHC at 888-466-2219 or apply online at healthhelp.ca.gov.

Supporting Your Appeal

Include evidence of:

  • FDA approval for your specific indication (infantile spasms or refractory complex partial seizures)
  • Clinical response documented through seizure diaries
  • REMS compliance with required vision monitoring
  • Specialist support from pediatric neurologist or epileptologist

From our advocates: We've seen vigabatrin appeals succeed when families provide detailed seizure logs showing clear improvement and demonstrate consistent vision monitoring compliance. The key is documenting that this specific medication—not alternatives—controls seizures that were previously refractory to multiple other treatments. California's IMR process is particularly effective for rare seizure medications when the medical necessity is well-documented.

FAQ

How long does Aetna CVS Health prior authorization take for vigabatrin renewal? Standard renewals take 30-45 days. Expedited reviews for urgent situations are completed within 72 hours. Submit 30 days before expiration to avoid coverage gaps.

What if vigabatrin is removed from Aetna's formulary? You can request a formulary exception through your neurologist. Provide documentation that preferred alternatives failed or caused intolerable side effects. California residents can appeal denials through DMHC's IMR process.

Does step therapy apply to vigabatrin renewals? Typically no, since vigabatrin is reserved for specific refractory seizure types. However, if you're switching between vigabatrin products (Sabril vs. generic), Aetna may require trying preferred options first unless medically contraindicated.

What happens if I miss required vision monitoring? REMS program compliance is mandatory for vigabatrin approval. Missing vision exams will likely result in coverage denial. Schedule makeup appointments immediately and provide documentation to your neurologist for renewal submissions.

How much does vigabatrin cost without insurance in California? Generic vigabatrin costs approximately $4,557 for 100×500mg tablets. Brand Sabril can exceed $19,000 for the same quantity. Patient assistance programs through manufacturers may reduce costs for eligible patients.
