ICD-10 Code B02.32 – Zoster iridocyclitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.32 – Zoster iridocyclitis
What it is
B02.32 identifies iridocyclitis caused by herpes zoster infection. Use it when the record shows shingles involving the eye’s iris and ciliary body.
Clinical signs
Documentation may note eye pain, redness, photophobia, blurred vision, or anterior uveitis findings. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents zoster iridocyclitis, herpes zoster anterior uveitis, or a similar diagnosis affecting the anterior segment of the eye. It fits confirmed ocular involvement linked to zoster, not just facial shingles. Check documentation if the chart only mentions eye irritation or rash near the eye.
Do not use for
Do not use B02.32 for uncomplicated shingles without eye involvement or for nonspecific conjunctivitis. If the diagnosis is uncertain or another ocular condition is documented, check documentation.
Coding tip
Code the zoster eye complication only when the provider clearly links the ocular inflammation to herpes zoster.
