Step-by-Step: Fastest Path to Approval
1. Verify Your Coverage Your doctor should check if Nourianz appears as "PA" (prior authorization) or "ST" (step therapy) in your specific Aetna plan's drug guide. Virginia residents on fully insured plans may have step therapy protections, but prior authorization still applies.
2. Document Your OFF Episodes Complete a Parkinson's disease diary for at least 3 consecutive days, tracking ON time and OFF time (tremors, stiffness, slow movements). Most insurers require ≥2-3 hours of daily OFF time despite optimized levodopa/carbidopa.
3. Gather Step Therapy Documentation Your neurologist needs records showing you've tried and failed (or couldn't tolerate) at least one of these standard adjuncts:
- Amantadine (immediate or extended-release)
- MAO-B inhibitor (rasagiline, selegiline, safinamide)
- COMT inhibitor (entacapone, opicapone, tolcapone)
4. Submit Prior Authorization Your doctor submits Aetna's PA form via Availity portal or fax to 1-888-267-3277 (specialty drugs). Include your PD diagnosis, stable levodopa regimen ≥4 weeks, prior medication failures, and OFF episode diary.
5. Track Decision Timeline Aetna has up to 72 hours for standard pharmacy PA decisions. If urgent, request expedited review (≤24 hours) with medical justification.
6. Appeal if Denied File internal appeal within 180 days using denial letter instructions. If still denied, Virginia residents can request free external review with Form 216-A within 120 days.
7. Consider Support Programs While pursuing approval, check Nourianz manufacturer programs and Virginia assistance resources to help with costs.
Read Your Denial Letter
When Aetna denies Nourianz, look for these specific reasons in your denial letter:
- "Step therapy not met": You haven't tried required medications first
- "Medical necessity not established": Insufficient OFF episode documentation
- "Non-formulary": Drug isn't on your plan's preferred list
- "Quantity limits exceeded": Requesting more than FDA-approved dosing
- "Provider not in network": Prescription from non-Aetna neurologist
Each denial reason has a specific fix. Don't guess—the exact language matters for your appeal strategy.
Clinician Corner: When writing medical necessity letters for Nourianz, include: (1) confirmed Parkinson's diagnosis with ICD-10 code G20, (2) current levodopa/carbidopa regimen and duration, (3) specific prior adjunct trials with dates, doses, and documented outcomes, (4) quantified OFF episodes from patient diary, and (5) treatment goals (reduced OFF time, improved function). Reference FDA labeling showing 20-40mg daily dosing for OFF episodes.
Common Denial Reasons & How to Fix Them
| Denial Reason | How to Overturn |
|---|---|
| Step therapy not completed | Submit records of amantadine, MAO-B, or COMT inhibitor trial with specific adverse effects, lack of efficacy, or contraindications |
| Insufficient OFF documentation | Provide 3-day patient diary showing ≥2-3 hours daily OFF time; include neurologist notes confirming symptoms |
| Non-formulary drug | Request formulary exception with medical necessity letter explaining why preferred alternatives failed |
| Prescriber not specialist | Have neurologist submit PA or provide consultation note supporting primary care prescription |
| Quantity limits | Verify dosing matches FDA labeling (20-40mg daily); adjust if needed |

FAQ
How long does Aetna CVS Health prior authorization take in Virginia? Standard PA decisions: up to 72 hours. Expedited/urgent requests: ≤24 hours. Medicare Part D follows federal timelines (72 hours standard, 24 hours expedited).
What if Nourianz is non-formulary on my Aetna plan? Request a formulary exception with medical necessity documentation. Show why preferred alternatives (amantadine, MAO-B/COMT inhibitors) failed or caused adverse effects.
Can I request an expedited appeal in Virginia? Yes, if waiting for standard review (30-60 days) would seriously jeopardize your health. Your doctor must complete Form 216-C certifying urgency for external review.
Does Virginia's step therapy protection apply to my Aetna plan? Only if you have a fully insured Aetna plan (not self-funded employer coverage). Even with protection, prior authorization may still be required.
What counts as adequate OFF episode documentation? Most insurers want ≥2-3 hours daily OFF time documented via 3+ day patient diary, plus neurologist notes confirming symptoms impact function.
How much does Nourianz cost with Aetna coverage? Depends on your formulary tier and benefit design. Specialty tier copays typically range $40-$100+ monthly. Check your specific plan documents.
Can I appeal to Virginia if my employer plan is self-funded? Only if your employer opts into Virginia's external review process. Many Virginia-headquartered employers do participate. If not, federal external review through HHS may be available.
What happens if I miss the 120-day external review deadline? Virginia's deadline is firm. Focus on filing internal appeals promptly to preserve external review rights. Contact the Bureau of Insurance immediately if you're near the deadline.
