ICD-10 Code B02.3 – Zoster ocular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.3 – Zoster ocular disease
What it is
B02.3 identifies herpes zoster involving the eye or surrounding ocular structures. Use it when shingles affects the eye region and the diagnosis is documented as ocular zoster.
Clinical signs
Findings may include eye pain, redness, tearing, photophobia, eyelid rash, or corneal involvement. Clinical features vary; refer to documentation.
When to use this code
Use B02.3 when the provider documents zoster ophthalmicus, herpes zoster of the eye, or other ocular involvement from shingles. It is appropriate when the eye condition is the reason for the visit or a confirmed diagnosis in the record.
If the chart only notes shingles without eye involvement, do not assume this code. Check documentation for laterality, ocular findings, and whether the eye itself is affected.
Do not use for
Do not use this code for uncomplicated herpes zoster without ocular involvement. Also avoid it when the record mentions only skin lesions on the face or scalp and no eye disease is documented.
Coding tip
Code B02.3 only when the provider clearly ties herpes zoster to ocular disease; otherwise, check documentation.
