Frequently Asked Questions

How long does Aetna CVS Health prior authorization take in Pennsylvania? Standard prior authorizations typically take 30-45 days. Expedited reviews for urgent cases may be completed within 72 hours if clinical urgency is documented.

What if iLink® is considered non-formulary by my plan? Request a formulary exception with medical necessity documentation. Emphasize that iLink® is the only FDA-approved corneal cross-linking system available in the United States.

Can I request an expedited appeal if my keratoconus is worsening rapidly? Yes, both Aetna's internal appeals and Pennsylvania's external review offer expedited processes (72 hours) when rapid disease progression threatens vision.

Does step therapy apply to iLink® corneal cross-linking? Step therapy is typically not required for FDA-approved iLink® when treating progressive keratoconus, but verify with your specific plan as requirements may vary.

What happens if I use an out-of-network provider? Out-of-network providers may result in denial or significantly higher out-of-pocket costs. Consider switching to an in-network cornea specialist or requesting a network exception with medical justification.

How do I find cornea specialists experienced with iLink® in Pennsylvania? Use Aetna's provider directory and search for ophthalmologists specializing in corneal diseases. Confirm they perform FDA-approved iLink® procedures.

What documentation should I keep during the appeals process? Maintain copies of all correspondence, denial letters, medical records, topography results, pachymetry reports, and submission confirmations. Pennsylvania's external review process requires comprehensive documentation.

Can Pennsylvania's external review overturn Aetna's denial even if it's a coverage exclusion? Pennsylvania's external review covers denials based on medical necessity, appropriateness, and whether treatments are investigational. Exclusions for non-covered benefits are generally not eligible for external review.
