Corneal ectasia, right eye

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

What This Code Means

A condition where the cornea of the right eye becomes abnormally thin and bulges outward, causing a cone-like protrusion.

Coding Tips

  • •Ectasia indicates corneal thinning with outward bulging; distinguish from keratoconus which is a specific type of ectasia
  • •Ensure documentation clearly identifies the right eye and confirms ectasia rather than other corneal deformities
