ICD-10 Code B02.30 – Zoster ocular disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.30 – Zoster ocular disease, unspecified
What it is
B02.30 identifies herpes zoster affecting the eye when the specific ocular site is not documented. Use it for shingles-related eye involvement without a more precise eye diagnosis.
Clinical signs
Findings may include painful vesicular rash in a trigeminal distribution, eye redness, tearing, photophobia, or decreased vision. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states zoster ophthalmicus, ocular shingles, or herpes zoster eye disease but does not specify a more detailed ocular manifestation. It also fits when eye involvement is documented without laterality or exact structure. Check documentation if corneal, eyelid, or other specific eye findings are named.
Do not use for
Do not use it for shingles without eye involvement, or when a more specific zoster eye code is documented. Do not assume ocular disease from facial rash alone.
Coding tip
Query for the exact ocular site if the note mentions eye involvement but gives no clear diagnosis.
