Set Your Goal: What Approval Requires

Cigna requires prior authorization for iLink® corneal cross-linking, and success depends on documented progressive keratoconus. Your partnership with your ophthalmologist centers on three core requirements:

Coverage Requirements at a Glance:

Requirement What It Means Documentation Needed Timeline
Progressive keratoconus diagnosis ICD-10 H18.601-H18.609 Serial corneal topography 6-12 months
Measured progression Kmax increase ≥1.0 diopter Comparative imaging reports 12 months minimum
FDA-approved protocol Epithelium-off procedure only iLink® system confirmation At time of treatment
Minimum corneal thickness ≥400 microns Pachymetry measurement Current assessment

The goal isn't just getting approval—it's building a comprehensive case that demonstrates medical necessity while following Cigna's coverage policy exactly.

Visit Preparation: Building Your Case

Before your appointment, prepare a detailed timeline that helps your ophthalmologist understand your progression and document medical necessity effectively.

Symptom Timeline to Document:

  • When you first noticed vision changes
  • Progression of visual symptoms (blurring, halos, light sensitivity)
  • Impact on daily activities (driving, reading, work performance)
  • Any episodes of sudden vision changes

Prior Treatments and Outcomes:

  • Glasses prescriptions and how often they've changed
  • Contact lens trials (rigid gas permeable, scleral lenses)
  • Success or failure with each correction method
  • Side effects or intolerance issues

Functional Impact Notes: Create a brief written summary of how keratoconus affects your life. This helps your doctor craft a compelling medical necessity letter that goes beyond clinical measurements.

Tip: Bring a list of specific activities that have become difficult. Cigna's reviewers need to understand the real-world impact, not just the clinical progression.

Evidence Kit: Clinical Documentation

Your ophthalmologist needs specific clinical evidence to meet Cigna's medical necessity criteria. Help them gather comprehensive documentation by understanding what's required.

Essential Clinical Evidence:

  1. Serial Corneal Imaging: Topography or tomography performed at least 6-12 months apart showing measurable progression
  2. Keratometry Progression: Documentation of Kmax increase ≥1.0 diopter over 12 months
  3. Visual Acuity Changes: Best-corrected visual acuity decline ≥1 line on eye chart
  4. Corneal Thickness: Current pachymetry confirming ≥400 microns at thinnest point

Supporting Documentation:

  • Complete eye exam records
  • Previous glasses/contact lens prescriptions
  • Any prior surgical history
  • Family history of keratoconus (if applicable)

Your role is ensuring your provider has access to all previous eye care records. Contact former providers to request imaging and exam records be sent directly to your current ophthalmologist.

Medical Necessity Letter Structure

The medical necessity letter is crucial for Cigna approval. While your ophthalmologist writes this document, understanding its structure helps you provide relevant information during your visit.

Essential Letter Components:

Patient Identification Section:

  • Full name, date of birth, Cigna member ID
  • Explicit keratoconus diagnosis with ICD-10 code
  • Date of initial diagnosis

Clinical Rationale Section:

  • Documentation of progressive keratoconus with specific measurements
  • Serial imaging results showing Kmax progression
  • Failed conservative treatments (glasses, contact lenses)
  • Current visual acuity and functional limitations

Treatment Justification:

  • Explanation of why iLink® cross-linking is medically necessary
  • Risk of continued progression without treatment
  • Potential need for corneal transplant if untreated
  • Confirmation of FDA-approved protocol use

Professional Guidelines Reference:

  • Citation of relevant ophthalmology society recommendations
  • Reference to peer-reviewed studies supporting cross-linking efficacy
Note: Your ophthalmologist may use templates, but personalized details about your specific progression and functional impact strengthen the letter significantly.

Peer-to-Peer Review Support

If Cigna's initial review results in denial, your ophthalmologist can request a peer-to-peer review with Cigna's medical director. Your preparation helps make this conversation more effective.

How to Support Your Provider:

Availability Windows: Provide your doctor's office with your preferred contact times in case Cigna needs additional patient information during the peer-to-peer call.

Concise Case Summary: Help your provider prepare a one-page summary including:

  • Timeline of progression with specific measurements
  • Failed treatments and why they're inadequate
  • Functional impact on your daily life
  • Risk of vision loss without intervention

Documentation Ready: Ensure all supporting records are easily accessible in your medical file for immediate reference during the call.

The peer-to-peer review often resolves denials when the clinical evidence clearly supports medical necessity. Cigna's formulary exception process allows for expedited review within 24 hours if your condition poses serious health risks.

After-Visit Documentation

Proper documentation after your visit ensures nothing falls through the cracks and provides a paper trail for potential appeals.

What to Save:

  • Copy of the prior authorization request
  • Medical necessity letter
  • All imaging reports and measurements
  • Visit summary with treatment plan
  • Any correspondence with Cigna

Portal Communication: Use your provider's patient portal to:

  • Request copies of all submitted documents
  • Ask for updates on prior authorization status
  • Communicate any changes in symptoms or vision

Follow-Up Timeline:

  • Standard review: 5-7 business days
  • Expedited review: 24-72 hours (if urgent)
  • Follow up if no response within expected timeframe

Respectful Persistence Strategy

Getting insurance approval sometimes requires persistent but professional follow-up. Here's how to work effectively with your provider's office.

Update Cadence:

  • Week 1: Confirm submission and get confirmation number
  • Week 2: Check status if no response received
  • Week 3: Escalate to peer-to-peer if initial denial received

Professional Escalation:

  • Start with your provider's office staff
  • Request to speak with the practice manager if needed
  • Ask your ophthalmologist to escalate directly with Cigna

Documentation of Communications: Keep a log of all calls including:

  • Date and time of contact
  • Person spoken with
  • Reference numbers provided
  • Next steps discussed
From our advocates: We've seen cases where persistent but polite follow-up led to approval after initial denials. One patient's provider discovered missing documentation during a follow-up call that, once submitted, resulted in immediate approval. The key is staying engaged without being demanding.
