Before You Start: Plan Verification

Check Your Coverage Basics

Confirm formulary status: Access your specific plan's formulary through Humana's drug list portal or call customer service. Nourianz typically appears on Tier 3 (Non-Preferred Drug) or higher specialty tiers.

Check network status: Ensure your prescribing physician is in-network with Humana to avoid additional coverage complications.

Gather Required Documentation

OFF-time documentation Patient diary showing ≥2.5 hours daily OFF episodes Parkinson.org symptom diary or APDA tools

Clinician Corner: Medical Necessity Letter Essentials

  • Prior treatments: Specific medications tried, doses, duration, and reasons for discontinuation
  • Clinical rationale: Reference FDA labeling for Nourianz as adjunctive therapy for OFF episodes
  • Monitoring plan: How you'll assess response and manage potential side effects

Common Denial Reasons & Solutions

Denial Reason Solution Strategy
Insufficient step therapy Submit detailed records of failed trials with specific reasons for discontinuation
Missing OFF-time documentation Provide structured patient diary with quantified daily OFF periods
No concurrent carbidopa/levodopa Document current therapy with doses and stability duration
Non-formulary status Request formulary exception with medical necessity justification
Quantity limits exceeded Provide clinical rationale for higher doses with safety monitoring plan
From our advocates: We've seen PA approvals within 48 hours when neurologists include specific OFF-time quantification and clearly document why standard adjunctive therapies failed. The key is painting a complete clinical picture rather than just checking boxes on the PA form.

FAQ

How long does Humana PA take in New York? Standard review takes up to 30 days; expedited urgent requests receive decisions within 72 hours. Electronic submissions through the provider portal typically process faster than fax submissions.

What if Nourianz is non-formulary on my plan? Request a formulary exception by demonstrating that covered alternatives are ineffective or cause adverse effects. Your physician must provide clinical justification for why Nourianz is medically necessary.

Can I appeal if I've tried step therapy outside New York? Yes, document your prior therapy trials regardless of where they occurred. Include pharmacy records and physician notes from previous states or providers.

Does Humana require a neurologist to prescribe Nourianz? While not always mandatory, neurologist prescriptions carry more weight in PA decisions. Primary care providers can prescribe but should include neurology consultation notes when available.

What happens if I miss the appeal deadline? New York's external appeal deadline is 4 months from your final internal denial. If you miss this deadline, you lose the right to external review, though you may still request a new PA if your clinical situation changes.

How often do I need to renew prior authorization? Initial approvals typically last 6 months to 1 year. Renewal requires documentation of continued medical necessity, treatment response, and absence of significant adverse effects.
