ICD-10 Code B02.29 – Other postherpetic nervous system involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B02.29 – Other postherpetic nervous system involvement
What it is
B02.29 identifies nervous system complications that persist after herpes zoster and do not fit a more specific postherpetic diagnosis. It tells you the aftereffects are neurologic rather than simple skin pain.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent neuropathic pain, sensory changes, weakness, or other nerve-related deficits after a shingles episode.
When to use this code
Use this code when the record documents a postherpetic nervous system complication and no more specific ICD-10-CM code applies. It is appropriate when the provider links the neurologic finding to prior herpes zoster. If the note only describes rash or acute shingles, use an acute zoster code instead.
Do not use for
Do not use it for uncomplicated herpes zoster, postherpetic neuralgia, or non-neurologic skin findings. Check documentation if the complication is described more specifically elsewhere.
Coding tip
Code the documented neurologic sequela, and verify that the provider explicitly connects it to prior zoster.
