Schedule comprehensive eye exam including:

  • Corneal topography (Pentacam or similar)
  • Pachymetry measurements
  • Best-corrected visual acuity
  • Review of prior imaging (bring all previous scans)

  • Medical necessity letter
  • Serial topography reports
  • Clinical notes documenting failed conservative treatment

Timeline: 1-3 business days for standard review, up to 72 hours for expedited requests.

Medical Necessity Documentation

Clinician Corner: Essential Letter Components

Your ophthalmologist's medical necessity letter should include:

Patient History:

  • Diagnosis with ICD-10 code (H18.601-H18.609)
  • Symptom progression (vision changes, contact lens intolerance)
  • Failed conservative treatments

Clinical Evidence:

  • Serial topography showing Kmax increase ≥1.0D over 12+ months
  • Current pachymetry measurements (≥400 µm required)
  • Visual acuity decline documentation
  • Photos of corneal signs if applicable

Treatment Rationale:

  • FDA approval of iLink® system (2016)
  • AAO guidelines supporting early intervention
  • Risk of progression to corneal transplant without treatment
  • Expected outcomes and monitoring plan
Tip: Include specific measurements in your letter. Instead of "worsening keratoconus," write "Kmax increased from 50.2D to 51.8D over 14 months, with new inferior steepening on topography."

Common Denial Reasons & Solutions

Denial Reason Solution Strategy Key Documentation
"Experimental/Investigational" Emphasize FDA approval since 2016 FDA approval letter, Glaukos iLink® page
"Insufficient Progression" Submit additional topography from different time points 12+ months of serial imaging, visual acuity records

"Alternative Treatments Available" Document failure/contraindications to RGP lenses, Intacs Contact lens fitting records, intolerance documentation

Appeals Process in New York

New York residents have exceptionally strong appeal rights through the state's external review system.

Internal Appeal (First Step)

  • Deadline: 60 days from denial notice
  • How to file: Call 1-800-833-6917 or submit through member portal
  • Timeline: 30 days for standard, 72 hours for expedited
  • Required: Original denial letter, additional medical records, physician statement

External Appeal (Second Step)

If your internal appeal is denied, you can request an external review through the New York Department of Financial Services.

  • Deadline: 4 months after final internal denial
  • Cost: $25 (waived for financial hardship or Medicaid)
  • Timeline: 30 days standard, 72 hours expedited for urgent cases
  • Process: Independent medical experts review your case
  • Success rate: External reviews overturn many denials when proper documentation is provided
Note: New York's external appeal decisions are binding on insurers. If you win, Humana must cover the treatment and refund your appeal fee.

When to Request Expedited Review

Request expedited processing if:

  • Your keratoconus is rapidly progressing
  • You're at risk of corneal scarring
  • Delay could result in need for corneal transplant

FAQ

How long does Humana prior authorization take for iLink®? Standard PA decisions are issued within 1-3 business days. Expedited requests (for urgent cases) are processed within 72 hours per CMS requirements.

What if my ophthalmologist says I need CXL but Humana denies it? File an internal appeal immediately, then consider external review through New York DFS. Many denials are overturned when proper progression documentation is provided. Counterforce Health specializes in helping overturn these denials with evidence-backed appeals.

Can I get iLink® covered if I don't have 12 months of progression data? Coverage is possible with shorter timeframes if progression is rapid or you have other supporting evidence. Your ophthalmologist should document all available clinical findings.

Does step therapy apply to corneal cross-linking? Humana typically requires documentation that glasses and contact lenses are inadequate before approving CXL, but this isn't formal step therapy since CXL treats disease progression, not just vision correction.

What if my current ophthalmologist isn't in Humana's network? You can request a single-case agreement for out-of-network coverage, especially if in-network specialists aren't available in your area. Alternatively, obtain a referral to an in-network corneal specialist.

Can I appeal to New York state if Humana is my employer's plan? Yes, New York's external appeal law applies to all health plans regulated in the state, including employer-sponsored plans, not just individual market plans.

From Our Advocates

We've seen many successful appeals for corneal cross-linking when patients provide comprehensive progression documentation. One key factor is ensuring your ophthalmologist clearly explains why CXL is disease-modifying treatment, not just vision correction, and emphasizes the FDA approval status. The combination of serial topography, clinical photos, and a detailed medical necessity letter addressing each coverage criterion significantly improves approval odds.
