Keratoconus, unspecified, left 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, affecting the left eye, without specification of whether it is stable or worsening.

Coding Tips

  • •This is an unspecified keratoconus code; if documentation indicates stable or unstable status, use the more specific codes H18.612 or H18.622
  • •The '02' ending specifically indicates the left eye; verify laterality in the medical record
