ICD-10 Code G96.1 – Disorders of meninges, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96.1 – Disorders of meninges, not elsewhere classified
What it is
G96.1 identifies a disorder affecting the meninges, the protective membranes around the brain and spinal cord, when the condition does not fit a more specific code. Use it only when documentation supports a meningeal disorder and no better category applies.
Clinical signs
Clinical features vary; refer to documentation. Meningeal disorders may be associated with headache, neck stiffness, neurologic symptoms, or abnormal imaging or cerebrospinal fluid findings, depending on the underlying cause.
When to use this code
Use this code when the provider documents a nonspecific disorder of the meninges and gives no more exact diagnosis. It may apply when the chart describes meningeal involvement, but the record does not support a more specific code. Review the note carefully for the underlying condition.
Do not use for
Do not use G96.1 for clearly identified meningitis, meningeal cysts, or other specific coded disorders. If the documentation names a different diagnosis, code that condition instead.
Coding tip
Query the provider when the record says “meningeal disorder” without a specific diagnosis, because specificity often changes the code selection.
