ICD-10 Code B02.2 – Zoster with other nervous system involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.2 – Zoster with other nervous system involvement
What it is
B02.2 identifies herpes zoster with involvement of the nervous system beyond the skin rash. Use it when documentation shows shingles affecting nerves or neurologic structures other than the brain or meninges.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see dermatomal pain, weakness, sensory changes, or other neurologic deficits occurring with a zoster eruption.
When to use this code
Use B02.2 when the provider documents shingles with other nervous system involvement, such as neuritis or radicular symptoms linked to herpes zoster. Code it when the nervous system complication is clearly attributed to zoster and is not better described by another specific B02 code.
Do not use for
Do not use this code for uncomplicated herpes zoster limited to the skin. If the record describes zoster encephalitis, meningitis, or postherpetic neuralgia, check documentation and use the more specific code.
Coding tip
Look for the exact neurologic complication named by the provider and code the most specific B02 option supported by documentation.
