ICD-10 Code B02.34 – Zoster scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.34 – Zoster scleritis
What it is
B02.34 identifies scleritis caused by herpes zoster infection. Use it when the sclera is inflamed in the setting of shingles, especially with documented ocular involvement.
Clinical signs
Typical findings include eye pain, redness, and tenderness, with inflammation involving the sclera. Clinical features vary; refer to documentation for the exact ocular findings and laterality.
When to use this code
Assign B02.34 when the provider documents zoster scleritis, herpes zoster affecting the sclera, or shingles with scleritis. Use the code only when the record clearly links the scleritis to zoster. If the note mentions eye involvement but does not specify scleritis, check documentation.
Do not use for
Do not use this code for nonspecific conjunctivitis, keratitis, or iritis without scleral involvement. Also avoid it when herpes zoster is present but scleritis is not documented.
Coding tip
Confirm the provider explicitly documents both zoster and scleritis before assigning B02.34.
