Herpes zoster with meningitis

This code represents a viral infection characterized by a painful rash (shingles) caused by the varicella-zoster virus, complicated by inflammation of the membranes surrounding the brain and spinal cord (meningitis). The meningitis is a direct consequence of the herpes zoster infection.

This code is appropriate when documentation clearly indicates a diagnosis of herpes zoster and a concurrent or subsequent diagnosis of meningitis, with a causal link established between the two. This typically occurs in patients presenting with shingles who develop symptoms such as headache, fever, and nuchal rigidity, confirmed by CSF analysis.

• Always ensure documentation explicitly links the meningitis to the herpes zoster infection.
• Do not use this code if the meningitis is due to another etiology; consider codes from the 320-322 series for other forms of meningitis.
• Code any associated neurological manifestations or complications separately, if applicable.
