Why Florida State Rules Matter for Xyrem Coverage

Florida's insurance laws work alongside federal Medicare regulations to protect your coverage rights. For Humana Medicare Advantage and Part D plans in Florida, you benefit from both federal appeal protections and Florida's consumer assistance programs.

Key Florida protections include:

  • Step therapy override rights under HB 459 (effective July 2022), requiring insurers to publish clear exemption procedures
  • 180-day appeal window for internal reviews, aligning with federal standards
  • External review access through the Florida Department of Financial Services for non-Medicare disputes
  • Consumer helpline support at 1-877-MY-FL-CFO for guidance and complaint filing
Note: Medicare Part D appeals follow federal timelines (65 days to file, 7 days for standard decisions), but Florida's DFS can help with procedural questions and insurer communication issues.

Humana's Prior Authorization Requirements

Xyrem requires prior authorization under virtually all Humana Medicare plans in Florida. Here's what you need to know:

Medical Necessity Criteria

Humana typically requires documentation of:

  • Failed or inappropriate alternatives (modafinil, armodafinil, stimulants)
  • Cataplexy symptoms or excessive daytime sleepiness despite other treatments
  • Sleep study results supporting the diagnosis
  • REMS program enrollment confirmation

REMS Program: Your First Step

Before Humana will even consider covering Xyrem, both you and your prescriber must be enrolled in the FDA-mandated Risk Evaluation and Mitigation Strategy (REMS) program.

Step-by-Step REMS Enrollment

  1. Prescriber Certification (One-time requirement)
  2. Patient Enrollment (One-time, unless 6+ month gap)
  3. Pharmacy Verification
    • Xyrem can only be dispensed by REMS-certified pharmacies
    • Most patients use the central specialty pharmacy system
    • Pharmacy coordinates with your insurance
Tip: Download and review the REMS Prescriber Brochure with your doctor to understand all requirements upfront.

Step Therapy Protections in Florida

Florida law (HB 459) requires insurers to provide clear step therapy exemption procedures. If Humana requires you to try other narcolepsy medications first, you can request an override.

Medical Exception Criteria

You may qualify for a step therapy exemption if:

  • Previous medications were ineffective for your narcolepsy symptoms
  • Delay would cause serious health consequences (document cataplexy episodes, driving concerns)
  • You're stable on current therapy (if switching from another plan)
  • Alternative drugs caused adverse effects (document side effects, intolerances)
  • Required medication isn't FDA-approved for your specific condition

Documentation That Helps

When requesting a step therapy override, include:

  • Medical records showing failed trials of modafinil, armodafinil, or stimulants
  • Prescriber letter explaining why Xyrem is medically necessary
  • Sleep study results and narcolepsy diagnosis confirmation
  • Evidence of cataplexy or treatment-resistant excessive daytime sleepiness

Appeals Process and Timelines

Level 2: Reconsideration (Independent Review)

  • Automatic if Level 1 denied: Proceeds to independent review entity (Maximus)
  • Timeline: 7 days standard, 72 hours expedited

  • Current medications aren't controlling symptoms
  • You're at risk for accidents due to excessive daytime sleepiness

Required Documentation for Appeals

Include with your appeal:

External Review Through Florida DFS

For non-Medicare coverage disputes or procedural complaints about Humana, Florida's Department of Financial Services provides additional support.

Filing a DFS Complaint

Contact: Florida DFS Consumer Helpline at 1-877-MY-FL-CFO (1-877-693-5236)

Online: File a complaint through the DFS website

What to Include:

  • Humana policy and member ID numbers
  • Clear description of the coverage dispute
  • Copies of denial letters and appeal responses
  • Documentation of attempts to resolve with Humana directly
Important: For Medicare Part D drug appeals, the federal process through independent review entities takes precedence over Florida's external review. DFS can help with procedural questions and insurer communication issues.

Phone Scripts and Templates

Calling Humana for Prior Authorization Status

Script for Members: "Hello, I'm calling to check on a prior authorization request for Xyrem, generic name sodium oxybate, for narcolepsy. My member ID is [ID number]. The request was submitted by Dr. [Name] on [date]. Can you tell me the status and what additional information might be needed? I'm enrolled in the required REMS program and can provide that documentation."

Peer-to-Peer Review Request

Script for Clinic Staff: "I'm calling to request a peer-to-peer review for a denied prior authorization. The member is [Name], ID [number]. The medication is Xyrem for narcolepsy with cataplexy. Dr. [Name] would like to speak with a Humana medical director about the medical necessity. The patient has failed multiple alternatives and is enrolled in the FDA REMS program. When can we schedule this review?"

DFS Consumer Helpline Script

"Hello, I'm a Florida resident with a Humana Medicare plan. My prior authorization for Xyrem was denied, and I believe the denial doesn't follow proper procedures. My policy number is [number]. I've attempted to resolve this with Humana but need guidance on my appeal rights. Can you help me understand the process and file a complaint if needed?"

Coverage Limits and ERISA Plans

Self-Funded Plan Differences

Important distinction: If you have Humana coverage through your employer, it may be a self-funded ERISA plan with different rules:

  • Federal law may preempt some Florida consumer protections
  • Appeals may go to different entities than Medicare processes
  • External review rights may be limited compared to individual Medicare plans

How to check: Look for "ERISA" language in your plan documents or ask HR about plan funding.

Medicare Advantage vs. Part D Differences

  • Medicare Advantage: Includes prescription coverage; appeals follow Medicare Advantage rules
  • Standalone Part D: Prescription-only coverage; specific Part D appeal timelines apply
  • Coordination issues: If you have both Medicare and employer coverage, coordination of benefits may affect Xyrem coverage

FAQ

How long does Humana prior authorization take for Xyrem in Florida? Standard prior authorization decisions take up to 7 calendar days for Medicare Part D plans. Expedited reviews (for urgent medical needs) must be completed within 72 hours. Source: CMS Medicare Appeals

What if Xyrem isn't on Humana's formulary? You can request a formulary exception (non-formulary coverage) by having your prescriber submit medical necessity documentation. The same 65-day appeal timeline applies if the exception is denied.

Can I request an expedited appeal for Xyrem? Yes, if your health could be seriously jeopardized by waiting for a standard 7-day decision. Frequent cataplexy episodes or dangerous excessive daytime sleepiness may qualify for expedited review.

Does step therapy apply if I was stable on Xyrem in another state? Florida law requires insurers to provide step therapy exemptions for patients who were previously approved for a medication within 90 days, with supporting documentation. Source: Florida Step Therapy Law

What's the difference between internal and external appeals? Internal appeals are reviewed by Humana staff or contracted reviewers. External appeals (for Medicare Part D) go to independent review entities like Maximus. You must complete internal appeals before external review.

How much does Xyrem cost without insurance? Retail prices can exceed $18,000 for a typical monthly supply. JazzCares offers patient assistance programs that may help reduce costs while you work on insurance approval.

Can Florida DFS overturn Humana's denial? For Medicare Part D denials, federal appeals processes take precedence. DFS can help with procedural complaints and facilitate communication with Humana, but cannot directly overturn coverage decisions made under federal Medicare rules.
