H18.713

Billable

Corneal ectasia, bilateral

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A condition where both corneas become abnormally thin and bulge outward, causing cone-like protrusions in both eyes.

Coding Tips

  • •Verify that ectasia is documented as bilateral; if only one eye is affected, use H18.711 or H18.712 instead
  • •Ectasia is a general term for corneal bulging; ensure this is not a more specific diagnosis like keratoconus
