Keratoconus, unstable, right 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 right eye, and the condition is actively progressing or worsening.

Coding Tips

  • •The 'unstable' designation indicates active progression; ensure documentation supports ongoing changes in corneal shape
  • •This code may indicate need for more frequent monitoring or intervention compared to stable keratoconus
