H16.003
BillableUnspecified corneal ulcer, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
An open sore or erosion on the clear front surface (cornea) of both eyes, where the specific cause or type of ulcer has not been identified. This condition can cause pain, redness, and vision problems if left untreated.
Coding Tips
- •Verify documentation specifies bilateral involvement; if only one eye is affected, use H16.001 (right eye) or H16.002 (left eye) instead
- •If the corneal ulcer type is documented (bacterial, fungal, viral, or traumatic), use a more specific code from the H16.0 subcategory rather than the unspecified code
