ICD-10 Code G96.198 – Other disorders of meninges, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96.198 – Other disorders of meninges, not elsewhere classified
What it is
This code identifies a disorder involving the meninges, the protective membranes around the brain and spinal cord, when the condition does not fit a more specific diagnosis. Use it only when documentation clearly supports a meningeal disorder and no other code is more precise.
Clinical signs
Clinical features vary; refer to documentation. Findings may include symptoms or imaging evidence suggesting meningeal involvement, but the record should specify the disorder rather than only nonspecific neurologic complaints.
When to use this code
Use G96.198 when the provider documents an unusual or unspecified meningeal disorder and no more specific ICD-10-CM code applies. It may fit cases described as other meningeal abnormality, lesion, or disorder of the meninges. If the note names a defined condition, code that diagnosis instead.
Do not use for
Do not use this code for meningitis, meningeal neoplasm, or traumatic meningeal injury when a more specific code exists. Check documentation if the chart only mentions headache, neurologic symptoms, or abnormal imaging without a clear meningeal diagnosis.
Coding tip
Code the documented meningeal disorder to the highest specificity available, and use G96.198 only as a fallback when the record supports “other” meningeal disease.
