H18.591
BillableOther hereditary corneal dystrophies, right eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes a genetic eye condition affecting the cornea (the clear front part of the eye) on the right side that doesn't fit into other specific hereditary corneal disease categories. These inherited disorders cause progressive damage to the cornea that can affect vision over time.
Coding Tips
- •Verify the specific type of hereditary corneal dystrophy documented by the provider, as more specific codes (H18.50-H18.59) may be available for conditions like lattice dystrophy, granular dystrophy, or Fuchs' dystrophy
- •Ensure laterality is correctly specified - use H18.591 for right eye only; use H18.592 for left eye and H18.593 for bilateral cases
