H18.601

Billable

Keratoconus, unspecified, right eye

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

What This Code Means

Keratoconus is a progressive eye condition where the cornea (the clear front part of the eye) gradually thins and develops a cone-like shape, affecting vision in the right eye. This code is used when the specific stage or severity of the condition is not specified.

Coding Tips

  • •Verify whether the condition is unilateral (one eye) or bilateral (both eyes) - use H18.601 for right eye only, H18.602 for left eye, and H18.603 for bilateral cases
  • •If documentation specifies the stage of keratoconus (acute hydrops, scarring, or other complications), use more specific codes from the H18.6- subcategory rather than the unspecified code
