Coverage Basics: Is iLink® Covered?
Which Humana Plans Cover iLink®?
Humana Medicare Advantage, commercial, and Medicaid plans in California typically cover iLink® corneal cross-linking when performed for progressive keratoconus or post-refractive ectasia. Coverage follows Humana's Keratoconus Surgical Treatments policy, which specifically includes conventional epithelium-off (epi-off) corneal collagen cross-linking as a covered surgical treatment.
Note: iLink® is the only FDA-approved corneal cross-linking system in the United States, using Photrexa/Photrexa Viscous solutions with the KXL UV device.

| Prior Authorization | Required for CPT 0402T | Humana Provider Portal |
| Progressive Keratoconus | ≥1.0 D increase in Kmax over 12 months | Serial topography reports |
| FDA-Approved System | Must use iLink (Photrexa + KXL) | Procedure documentation |
| In-Network Provider | Surgeon and facility must be contracted | Humana Provider Directory |

Clinician Corner: Medical Necessity Letter Checklist
Your ophthalmologist's letter should include:
- Diagnosis: Progressive keratoconus with ICD-10 codes (H18.601-H18.609)
- Progression documentation: Specific Kmax increases, cylinder changes, or myopic shift
- Failed conservative therapy: Glasses and contact lens limitations
- Procedure details: Confirmation of FDA-approved iLink system use
- Clinical rationale: Risk of continued progression without treatment
- Guideline support: Reference to AAO Preferred Practice Patterns
Timing and Urgency
Standard Processing Times
- Medicare Part D: 72 hours for coverage determination
- Medicare Advantage: Up to 30 days for pre-service decisions
- Commercial Plans: Typically 30 calendar days
- Expedited Reviews: 24-72 hours when delay could jeopardize health
When to Request Expedited Review
Request expedited processing if:
- Rapid keratoconus progression documented
- Risk of corneal perforation or severe visual loss
- Patient approaching age where CXL effectiveness decreases
Tip: For expedited requests, have your ophthalmologist clearly document why delay would "seriously jeopardize the patient's ability to regain maximum function."
Medical Necessity Criteria

- Increase of ≥1.0 D in manifest cylinder
- Myopic shift ≥0.50 D (spherical equivalent)
- Decrease of ≥0.1 mm in back optical zone radius (RGP wearers)
Required Clinical Documentation
- Corneal topography: Serial studies showing progression patterns
- Pachymetry: Central or thinnest measurement ≥400 μm
- Visual function: Best-corrected visual acuity decline or irregular astigmatism
- Conservative treatment failure: Documented limitations with spectacles/contact lenses
Costs and Financial Assistance

FAQ: Most Common Questions
Q: How long does Humana prior authorization take in California? A: Standard timeline is 72 hours for Medicare Part D, up to 30 days for Medicare Advantage. Expedited reviews are available in 24-72 hours when medically urgent.
