What This Guide Covers

This comprehensive guide helps patients with Parkinson's disease and their clinicians navigate Humana's prior authorization process for Nourianz (istradefylline) in Illinois. Whether you're dealing with your first PA request or appealing a denial, you'll find the exact forms, timelines, and strategies that work.

Nourianz is an oral adenosine A2A receptor antagonist that helps reduce "OFF" episodes when used alongside carbidopa/levodopa. At approximately $1,900-$2,100 per month, most insurance plans—including Humana—require prior authorization and step therapy before approval.

Note: This guide focuses on Humana Medicare Advantage and Part D plans. For Humana commercial plans, many principles apply, but specific forms and timelines may differ.

Check Your Exact Plan Type

Call the number on your Humana ID card to confirm:

  • Plan type: Medicare Advantage, Part D, or dual-eligible special needs plan
  • Formulary tier for Nourianz
  • Current PA requirements (these can change mid-year)
  • Specialty pharmacy requirements

Gather What You Need

Before starting your PA request, collect these essential documents:

Medical Documentation

  • Parkinson's diagnosis with ICD-10 code (G20.*)
  • OFF-episode documentation: frequency, duration, and functional impact
  • Current levodopa regimen: drug, dose, frequency, duration of use
  • Prior therapy history: what was tried, for how long, and why it failed

Step Therapy Documentation

Based on typical Humana requirements, you'll likely need evidence of:

  • One MAO-B inhibitor (rasagiline, selegiline, or safinamide)
  • One COMT inhibitor (entacapone, opicapone, or tolcapone)
  • Often amantadine or dopamine agonist trials
Tip: If certain drugs were contraindicated due to age, psychosis, or other conditions, have your neurologist document this clearly—it can satisfy step therapy requirements without actual trials.

Insurance Information

  • Humana member ID and group number
  • Copy of current insurance card
  • Any previous denial letters or EOBs

  • OFF-episode impact: hours per day, functional limitations, safety concerns

Step 4: Complete and Submit PA (Prescriber Office)

Timeline: 1-2 business days
Submission options:

  • Electronic PA via Humana provider portal (fastest)

  • Phone to provider services number on member ID card

Script: "I'm calling to check the status of a prior authorization for Nourianz submitted on [date]. The reference number is [number]."

Step 6: Follow Up on Decision (Within 7 days)

Timeline: Standard PA decisions within 7 calendar days
If approved: Coordinate with specialty pharmacy for fulfillment
If denied: Review denial letter for specific reasons and prepare appeal

Step 7: Appeal if Necessary (Within 65 days)

Timeline: Must file within 65 days of denial date
Action: Submit Part D redetermination request with additional clinical documentation

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Key Documents Needed
Step therapy not completed Document trial/failure of required drugs OR contraindications Pharmacy records, clinic notes showing adverse effects
Insufficient OFF documentation Provide detailed OFF diary and functional impact assessment 7-14 day symptom diary, ADL assessment
Not on stable levodopa Confirm current carbidopa/levodopa regimen and duration Prescription history, current medication list
Non-formulary Request formulary exception with medical necessity letter Comparative effectiveness data, guideline citations
Quantity limit exceeded Justify higher dose based on clinical factors Weight, metabolism, smoking status documentation

Appeals Playbook for Humana in Illinois

Internal Appeals (Level 1)

Timeline: 65 days to file from denial date
Decision timeframe: 7 days standard, 72 hours expedited
How to file:

  • Phone: Call number on Humana ID card, request "Part D redetermination"
  • Online: Humana member portal
  • Mail/Fax: Use addresses on denial letter

What to include:

  • Copy of original denial letter
  • Enhanced medical necessity letter addressing specific denial reasons
  • Additional clinical documentation (OFF diaries, medication trials)
  • Peer-reviewed literature supporting Nourianz use

External Review (Illinois-Specific)

If Humana upholds the denial, Illinois residents have strong additional rights under the Health Carrier External Review Act:

Timeline: Must file within 30 days of final adverse determination (shorter than most states)
Decision timeframe: Maximum 30 days for standard review
Cost: No fees for patients
How to file: Illinois Department of Insurance external review forms

Illinois Advantage: The state's external review process assigns board-certified specialists to review denials. For Parkinson's medications, this means a neurologist or movement disorder specialist will evaluate your case independently.

FAQ: Your Top Questions Answered

Q: How long does Humana prior authorization take for Nourianz in Illinois?
A: Standard decisions must be made within 7 calendar days. Expedited reviews (when health is at risk) take up to 72 hours. Source: Medicare regulations

Q: What if Nourianz isn't on my Humana formulary?
A: You can request a formulary exception by demonstrating medical necessity and showing that formulary alternatives aren't appropriate. This requires the same documentation as a standard PA plus comparative effectiveness arguments.

Q: Can I request an expedited appeal if I'm having severe OFF episodes?
A: Yes. If your prescriber certifies that waiting for a standard decision could seriously jeopardize your health, you can request expedited review with 72-hour decision timelines.

Q: Do I need a movement disorder specialist to prescribe Nourianz?
A: While not always required, having a neurologist or movement disorder specialist submit the PA significantly strengthens your case. Many policies show preference for specialist prescribers.

Q: What happens if I miss the 65-day appeal deadline?
A: You may lose your right to appeal that specific denial. However, you can submit a new coverage determination request with additional documentation. For Illinois external review, the deadline is even shorter at 30 days.

Q: How much does Nourianz cost without insurance?
A: Cash pricing ranges from approximately $1,900-$2,100 per month based on 30-tablet supply. Counterforce Health can help navigate coverage options to avoid these out-of-pocket costs.
