H18.629
BillableKeratoconus, unstable, unspecified eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A progressive eye condition where the cornea thins and changes into a cone-like shape in an unstable manner, but the specific eye affected is not documented.
Coding Tips
- •Use this code only when documentation does not specify which eye is affected; query provider if laterality can be determined
- •This is a less specific code; attempt to obtain clarification on unilateral vs. bilateral involvement
