ICD-10 Code B02.9 – Zoster without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.9 – Zoster without complications
What it is
B02.9 identifies herpes zoster, or shingles, when there are no documented complications. Use it for a localized zoster episode without mention of ophthalmic, neurologic, or other specified complications.
Clinical signs
Typical findings include a painful, unilateral vesicular rash in a dermatomal distribution. Clinical features vary; refer to documentation when the record does not clearly state the extent or any complication.
When to use this code
Use B02.9 when the provider documents shingles or herpes zoster and does not describe a complication. It is appropriate for routine outpatient or inpatient encounters focused on an uncomplicated zoster eruption. If the note names a complication, code that condition instead.
Do not use for
Do not use this code for zoster with ophthalmic, neurologic, or other specified complications. Also avoid it when the documentation is only “history of shingles” or when the diagnosis is uncertain; check documentation.
Coding tip
Look for complication wording in the assessment, because that changes code selection.
