What This Guide Covers

This guide helps patients with narcolepsy or idiopathic hypersomnia—and their healthcare providers—navigate Cigna's prior authorization process for Xywav (calcium, magnesium, potassium, sodium oxybates) in New Jersey. Whether you're facing an initial denial or planning ahead for coverage, you'll find step-by-step instructions, required forms, and appeal strategies specific to New Jersey's insurance landscape.

Xywav is a controlled substance that requires enrollment in a Risk Evaluation and Mitigation Strategy (REMS) program, making the approval process more complex than typical medications. This guide addresses those unique requirements while leveraging New Jersey's robust patient protection laws.

Before You Start: Coverage Basics

Verify Your Plan Details

Check your formulary status: Xywav typically appears on Cigna's specialty tier, requiring prior authorization regardless of your specific plan. Log into your Cigna member portal or call the number on your insurance card to confirm your plan's formulary.

Confirm your prescriber: Cigna requires Xywav to be prescribed by a sleep specialist or neurologist. General practitioners typically cannot obtain approval without specialist consultation.

Understand quantity limits: Cigna restricts Xywav to a 30-day supply per fill, with nightly dosing capped at 9 grams unless exceptional medical necessity is documented.

Follow-Up and Timelines

Standard Processing Times

Commercial plans: Cigna must respond within 15 calendar days for standard requests, 72 hours for urgent requests.

What to track:

  • Submission confirmation number
  • Expected decision date
  • Any requests for additional information

Sample Follow-Up Script

"Hi, I'm calling to check on the status of prior authorization request #[reference number] for Xywav submitted on [date]. Can you tell me if a decision has been made or if any additional information is needed?"

Document every call: Note the date, representative name, and any information provided.

If You Need More Information

Cigna may request additional documentation during their review. Common requests include:

  • More detailed prior treatment records
  • Updated sleep study results
  • Specialist consultation notes
  • Laboratory results ruling out other conditions

Response timeline: You typically have 14 days to provide additional information. Missing this deadline may result in an automatic denial.

If You're Denied: Appeals Process

Understanding Your Denial

Common denial reasons and solutions:

Denial Reason How to Address
"Not medically necessary" Submit peer-reviewed literature supporting Xywav use
"Step therapy not met" Document failed stimulant trials or contraindications
"REMS not verified" Provide updated REMS enrollment confirmation
"Prescriber not qualified" Confirm specialist credentials or obtain consultation

Internal Appeals Process

First-level appeal:

  • Must be filed within 180 days of denial
  • Submit via Cigna member portal or written request
  • Include all original documentation plus additional supporting evidence

Peer-to-peer review: Your prescriber can request a direct conversation with a Cigna medical director by calling 1-800-882-4462. This often resolves complex cases more quickly than written appeals.

Second-level appeal: If the first-level appeal is denied, you have 60 days to request a second-level review by a different medical director.

New Jersey External Review (IHCAP)

If Cigna denies your internal appeals, New Jersey residents have access to the Independent Health Care Appeals Program (IHCAP), managed by Maximus Federal Services.

IHCAP Process Overview

Eligibility: You must have completed Cigna's internal appeal process or be unable to complete it due to urgency.

Timeline to file: Within 4 months (120 days) of your final internal appeal denial.

How to apply: Submit your external appeal request directly to Maximus IHCAP.

IHCAP Decision Timeline

  • Preliminary review: Maximus notifies you within 5 business days if your appeal is accepted
  • Standard review: Decision within 45 calendar days
  • Expedited review: Decision within 48 hours for urgent cases

Cost: Free to you—insurers pay all review costs.

Binding decision: If IHCAP overturns Cigna's denial, Cigna must provide coverage as directed.

From our advocates: We've seen many New Jersey patients succeed with IHCAP appeals for specialty sleep medications when they include comprehensive medical literature and clear documentation of functional impairment. The key is presenting a complete picture of how the medication addresses unmet medical needs that generic alternatives couldn't resolve.
