H10.422
BillableSimple chronic conjunctivitis, left eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A long-lasting inflammation of the clear membrane covering the white part of the left eye and inner eyelid, characterized by redness, irritation, and discharge without infection. This condition persists over time and is not caused by bacteria or viruses.
Coding Tips
- •Verify laterality is documented in the medical record - this code specifically indicates the left eye, so ensure the provider has specified which eye is affected
- •Distinguish between simple chronic conjunctivitis and other types (allergic, infectious, chemical) as each has different code assignments; simple conjunctivitis lacks these specific etiologies
