ICD-10 Code B02.8 – Zoster with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.8 – Zoster with other complications
What it is
B02.8 identifies herpes zoster, or shingles, when it causes a complication not captured by a more specific zoster code. Use it when documentation shows zoster plus another complication, but the record does not support a narrower option.
Clinical signs
Typical findings include a painful, unilateral vesicular rash in a dermatomal pattern, with the documented complication varying by case. Clinical features vary; refer to documentation.
When to use this code
Use B02.8 when the provider documents shingles with an associated complication and no more specific ICD-10 code fits. This may include cases where the complication is described, but the chart does not support a separate, more exact zoster category. Check documentation for the named complication.
Do not use for
Do not use this code for uncomplicated zoster, postherpetic neuralgia alone, or disseminated zoster when a more specific code is documented. Avoid it when the record supports a different, more precise zoster diagnosis.
Coding tip
Code the documented complication as specifically as possible, and use B02.8 only when no more specific zoster code applies.
