H18.603

Billable

Keratoconus, unspecified, bilateral

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 in both eyes, without specification of whether it is stable or worsening.

Coding Tips

  • •This bilateral code should only be used when keratoconus affects both eyes; if only one eye is affected, use the appropriate unilateral code
  • •If stability status is documented, use H18.613 (stable) or H18.623 (unstable) instead
