Billable

Keratoconus, unspecified, unspecified 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 (clear front of the eye) becomes progressively cone-shaped, but the affected eye is not specified and stability status is unknown.

Coding Tips

  • •This is the least specific keratoconus code; always attempt to determine laterality (right, left, or bilateral) from the medical record
  • •Use only when documentation does not specify which eye or eyes are affected
