H18.553

Billable

Macular corneal dystrophy, bilateral

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

What This Code Means

A hereditary eye condition affecting both eyes where the cornea (the clear front part of the eye) develops cloudy spots in the central area, gradually causing vision problems. This is a genetic disorder that typically worsens over time.

Coding Tips

  • •Verify that the condition is documented as bilateral (affecting both eyes) before assigning this code; if only one eye is affected, use the unilateral code H18.551 instead
  • •This code is specific to macular corneal dystrophy; do not use it for other types of corneal dystrophies such as granular, lattice, or Fuchs dystrophy, which have separate codes
