ICD-10 Code B00.59 – Other herpesviral disease of eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B00.59 – Other herpesviral disease of eye
What it is
B00.59 identifies herpesvirus infection affecting the eye when the documentation does not fit a more specific herpes ocular code. Use it for other documented herpesviral eye disease. Check documentation.
Clinical signs
Clinical features vary; refer to documentation. Herpes ocular disease may include eye pain, redness, tearing, photophobia, blurred vision, or corneal involvement, but you should code only what the provider documents.
When to use this code
Use B00.59 when the record clearly states herpesviral disease of the eye and no more specific ICD-10-CM code applies. It is appropriate when the provider describes an ocular herpes infection without finer anatomic or clinical detail. If the note only says “herpes eye infection,” confirm whether a more specific diagnosis is documented.
Do not use for
Do not use this code for nonspecific eye irritation, bacterial conjunctivitis, or herpes infections outside the eye. If the documentation identifies a more specific herpes ocular condition, code that instead.
Coding tip
Verify the provider’s exact eye diagnosis and laterality details, then select the most specific herpes code available before defaulting to B00.59.
