Before You Start: Plan Verification
Before submitting your Nourianz prior authorization, confirm these basics:
- Plan type: Check if you have Aetna commercial, Medicare Advantage, or Medicaid managed care
- Pharmacy benefit: Nourianz is covered under pharmacy benefits (not medical), handled by CVS Caremark
- In-network prescriber: Ensure your neurologist is in Aetna's network to avoid coverage complications
- Current formulary: Verify Nourianz tier status in your 2025 plan documents at Aetna.com
Note: California residents with Aetna HMO plans fall under DMHC oversight, while some PPO plans are regulated by the California Department of Insurance (CDI). Both provide strong appeal rights.

California Appeals Process
California offers some of the strongest patient protections in the nation for insurance appeals.
Internal Appeal (Required First Step)
- Deadline: 180 days from denial notice
- How to file: Call 1-855-582-2025 or submit via Aetna member portal
- Timeline: Decision within 30 days (72 hours for urgent)
- Cost: Free
Independent Medical Review (IMR)
If your internal appeal is denied, California residents can request an Independent Medical Review through the Department of Managed Health Care (DMHC).
- Success rate: 55-69% for specialty medication denials
- Timeline: 45 days standard, 7 days expedited
- Cost: Completely free to patients
- How to apply: DMHC online portal or call 888-466-2219
From our advocates: We've seen Parkinson's patients succeed in IMR by emphasizing the functional impact of OFF episodes and providing detailed motor fluctuation diaries. The independent physicians reviewing these cases often understand the progressive nature of the disease better than initial utilization reviewers.
Required IMR Documentation
- Copy of internal appeal denial
- Complete medical records
- Prescriber letter explaining medical necessity
- Patient impact statement describing OFF episode effects on daily life

Yes. If your condition may seriously jeopardize your health, request expedited review. Aetna must decide within 24 hours, and California IMR expedited reviews are completed within 7 days.
Does step therapy apply if I failed medications in another state?
Yes, documented trials from other states count toward step therapy requirements. Provide prescription records and discontinuation reasons from your previous location.
