Understanding Your Cigna Plan Coverage

Cigna's coverage for Crysvita (burosumab) varies significantly by plan type. Here's what you need to know:

Coverage at a Glance

Plan Type Prior Authorization Specialty Pharmacy Key Requirements
Medicare Advantage Not required for Medical Oncology May be required Must use HCPCS J0584 billing
Commercial/Employer Required Accredo typically required XLH/TIO diagnosis, specialist oversight
Individual Market Required Express Scripts network Phosphate monitoring plan mandatory

According to Cigna's 2024 Medicare Advantage Medical Oncology drug list, Crysvita is listed without prior authorization requirements when properly coded.

For commercial plans, Cigna's coverage policy requires comprehensive clinical documentation before approval.

Prior Authorization Requirements

Step-by-Step: Fastest Path to Approval

  1. Verify Plan Type (Patient/Clinic)
    • Call Cigna member services using the number on your insurance card
    • Confirm if you have Medicare Advantage or commercial coverage
    • Timeline: Same day
  2. Gather Required Documentation (Clinic)
    • XLH genetic testing or biochemical confirmation
    • Serum phosphate levels (baseline and monitoring plan)
    • Prior therapy history (phosphate supplements, vitamin D analogs)
    • Timeline: 1-3 business days
  3. Submit Prior Authorization (Prescriber)
  4. Coordinate Specialty Pharmacy (Patient/Clinic)
    • If approved, medication typically ships through Accredo
    • Verify patient copay assistance enrollment
    • Timeline: 2-5 business days after approval

Medical Necessity Criteria

Cigna typically requires documentation of:

  • Confirmed diagnosis of XLH (genetic testing preferred) or TIO with unresectable tumor
  • Serum phosphate levels below age-adjusted normal ranges
  • Specialist management by endocrinologist or metabolic bone specialist
  • Monitoring plan for serum phosphate, kidney function, and clinical response
  • Contraindication documentation if unable to use conventional phosphate/vitamin D therapy

Reading Your Denial Letter

When Cigna denies Crysvita coverage, the letter will specify the reason. Common denial codes include:

Denial Reason What It Means Next Step
"Not medically necessary" Clinical criteria not met Submit additional clinical evidence
"Non-formulary" Drug not on preferred list Request formulary exception
"Quantity limits exceeded" Dosing frequency/amount questioned Provide weight-based dosing justification
"Experimental/investigational" Off-label use concern Cite FDA approval and clinical guidelines
Important: Note the appeal deadline in your denial letter. For Cigna, you typically have 180 days from the denial date to file an internal appeal.

First-Level Internal Appeal

What to Include in Your Appeal

Your internal appeal should address the specific denial reason with targeted evidence:

For "Not Medically Necessary" Denials:

  • Laboratory confirmation of hypophosphatemia
  • Genetic testing results (if available)
  • Documentation of skeletal manifestations
  • Prior treatment failures or contraindications
  • Specialist consultation notes

For "Non-Formulary" Denials:

  • Request formulary exception based on medical necessity
  • Document why formulary alternatives are inappropriate
  • Include peer-reviewed literature supporting Crysvita's efficacy

Appeal Submission Process

Submit your appeal through:

  • Cigna member portal (fastest option)
  • Fax: Use the appeals fax number on your denial letter
  • Mail: Send to the address specified in your denial letter
Tip: Always request expedited review if treatment delay could worsen your condition or cause irreversible harm.

Peer-to-Peer Review Strategy

If your written appeal is denied, request a peer-to-peer review. This allows your prescribing physician to speak directly with Cigna's medical director.

Preparation Checklist for Prescribers

  • Review patient's complete medical history
  • Prepare 3-5 key talking points about medical necessity
  • Have clinical guidelines and FDA labeling readily available
  • Document the call date, time, and medical director's name
  • Follow up in writing within 24 hours

Key Talking Points

  1. Diagnosis confirmation: "Patient has genetically confirmed XLH with persistent hypophosphatemia despite conventional therapy"
  2. Treatment failure: "Previous phosphate and calcitriol therapy resulted in nephrocalcinosis, requiring discontinuation"
  3. Clinical guidelines: "Current expert consensus recommends burosumab as first-line therapy for adult XLH"
  4. Monitoring plan: "We have established comprehensive phosphate monitoring protocols per FDA labeling"

North Carolina External Review Process

If Cigna upholds their denial after internal appeals, North Carolina residents can request an external review through the state's Smart NC program.

External Review Timeline

Review Type Deadline to Request Decision Timeline
Standard Review 120 days after final denial 45 calendar days
Expedited Review No specific deadline 4 business days

How to Request External Review

  1. Contact Smart NC: Call 1-855-408-1212 for assistance
  2. Complete forms: Download the external review request form
  3. Submit documentation: Include all medical records and appeal correspondence
  4. Follow up: You can submit additional evidence within 7 days of acceptance

The external review process in North Carolina has helped many patients access expensive rare disease treatments. According to available data, 61.1% of Smart NC external review requests are accepted for review, providing an important avenue when internal appeals fail.

From our advocates: "We've seen several North Carolina patients successfully obtain Crysvita coverage through external review after initial Cigna denials. The key was providing comprehensive genetic testing results and documenting failed conventional therapy attempts. While we can't guarantee outcomes, thorough documentation significantly improves your chances."
