H10.13
BillableAcute atopic conjunctivitis, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is an allergic inflammation of the clear membrane covering the white part of both eyes that develops suddenly. It causes itching, redness, and watery eyes due to an allergic reaction.
Coding Tips
- •Verify that the condition affects both eyes (bilateral) before assigning this code; if only one eye is affected, use H10.12 instead
- •Document the allergic trigger if known (pollen, pet dander, dust mites, etc.) as this may support medical necessity and help guide treatment
