H16.029
BillableRing corneal ulcer, unspecified eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A ring-shaped ulcer (open sore) that forms around the outer edge of the cornea (the clear front part of the eye), but the specific eye affected is not documented. This type of ulcer can cause pain, redness, and vision problems if left untreated.
Coding Tips
- •Use this code only when the documentation does not specify whether the right eye (H16.021), left eye (H16.022), or bilateral eyes (H16.023) are affected; always attempt to clarify laterality with the provider for more specific coding
- •Ring corneal ulcers are often associated with autoimmune conditions or severe infections, so review the medical record for underlying diagnoses that may need to be coded separately
