Keratoconus, unstable, 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 cone-shaped in the left eye, and the condition is actively progressing or worsening.

Coding Tips

  • •The 'unstable' designation indicates active progression; verify documentation supports ongoing changes
  • •Confirm left eye is the correct laterality and that the condition is not stable
