Why Washington State Rules Matter

Washington has some of the strongest patient protection laws in the country for insurance appeals. Unlike many states, Washington guarantees your right to an Independent Review Organization (IRO) that can override your insurer's medical necessity decisions. This is crucial for specialized treatments like corneal cross-linking, where insurers may not fully understand the vision-preserving benefits.

Key Washington Advantages:

  • 180-day appeal window (longer than federal minimum)
  • Binding external review through certified IROs
  • 72-hour expedited reviews for urgent cases
  • Strong regulatory oversight by the Office of the Insurance Commissioner

For Aetna CVS Health specifically, Washington's laws interact with their standard medical policies to create multiple appeal pathways when coverage is initially denied.

Prior Authorization Requirements

Aetna CVS Health requires comprehensive documentation before approving iLink® corneal cross-linking. Based on their clinical policy bulletin, you must demonstrate:

Medical Criteria:

  • Confirmed diagnosis of progressive keratoconus (ICD-10: H18.601-H18.609)
  • Documented progression through serial corneal topography showing increased curvature
  • Minimum corneal thickness of 400 microns via pachymetry
  • FDA-approved treatment using iLink® system with Photrexa riboflavin

Documentation Requirements:

  • Serial corneal topography (minimum 3-6 months apart showing progression)
  • Complete ophthalmologic examination notes
  • Visual acuity measurements and refractive history
  • Prior treatment attempts with contact lenses or other conservative measures
  • Detailed medical necessity letter from cornea specialist
Note: Aetna typically does not require step therapy for corneal cross-linking when FDA-approved systems are used for progressive keratoconus, unlike some other specialty treatments.

Step-by-Step: Fastest Path to Approval

1. Gather Clinical Evidence (Patient + Ophthalmologist)

  • Collect serial corneal topography showing Kmax progression
  • Document pachymetry readings ≥400 microns
  • Obtain detailed examination notes from cornea specialist
  • Timeline: 1-2 weeks if records exist

2. Verify Network Status (Patient)

3. Submit Prior Authorization (Ophthalmologist's Office)

  • Use Aetna provider portal or fax submission
  • Include all required documentation and ICD-10 codes
  • Timeline: Standard review 14-30 days

4. Follow Up on Decision (Patient + Provider)

  • Track authorization status through member portal
  • Request written denial if coverage is rejected
  • Expected: Decision within 30-45 days

5. Prepare Appeal if Denied (Patient)

  • Gather additional clinical evidence
  • Request peer-to-peer review with cornea specialist
  • Timeline: Must appeal within 180 days in Washington

When Aetna Denies: Understanding Your Rights

If Aetna CVS Health denies coverage for iLink® corneal cross-linking, Washington law provides strong protections. Common denial reasons include questioning medical necessity, requiring additional documentation, or citing policy exclusions.

Your Rights Under Washington Law:

  • Internal appeals through Aetna's process (required first step)
  • External review by Independent Review Organization (binding on Aetna)
  • Expedited appeals for urgent medical situations
  • Regulatory complaints through the Insurance Commissioner

The key is understanding that Washington's external review process can override Aetna's medical necessity determinations when an independent panel of specialists disagrees with the initial denial.

When to Contact the Washington Insurance Commissioner

The Washington Office of the Insurance Commissioner provides free consumer advocacy for insurance disputes. Contact them if:

  • Aetna fails to respond to appeals within required timeframes
  • You need help understanding your external review rights
  • You want to file a regulatory complaint about claim handling

Contact Information:

From our advocates: "We've seen many Washington patients successfully overturn Aetna denials for corneal cross-linking by emphasizing the FDA approval and progressive nature of their keratoconus. The key is thorough documentation of disease progression and working with a cornea specialist who understands the appeals process. While outcomes vary, patients who use Washington's external review process often find success when their clinical evidence is strong."
