G96.89 — Other specified disorders of central nervous system
Is G96.89 billable?
Yes, but G96.89 is an unspecified code. G96.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, G96.89 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting G96.89 — the more specific alternatives are listed below.
