ICD-10 Code B00.50 – Herpesviral Ocular Disease, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B00.50 – Herpesviral ocular disease, unspecified
What it is
B00.50 identifies herpesvirus infection involving the eye when the documentation does not specify a more exact ocular site or type. Use it for nonspecific herpesviral eye disease.
Clinical signs
Findings may include eye pain, redness, tearing, photophobia, or blurred vision. Clinical features vary; refer to documentation and confirm that the provider links the ocular findings to herpesviral disease.
When to use this code
Use this code when the record states herpesviral ocular disease, herpes of the eye, or similar wording without further detail. It also fits when the provider documents ocular involvement but does not name the cornea, conjunctiva, or another specific structure.
If laterality or the exact eye condition is not documented, this unspecified code may be appropriate. Code the most specific herpes eye diagnosis available when documentation supports it.
Do not use for
Do not use B00.50 for non-herpetic conjunctivitis, keratitis, or other eye disorders unrelated to herpesvirus. Check documentation if the note only mentions a history of herpes without current ocular disease.
Coding tip
Query for the exact ocular site and laterality when the provider records only “herpes eye” or “ocular herpes.”
