G40.901 — Epilepsy, unspecified, not intractable, with status epilepticus
Is G40.901 billable?
Yes, but G40.901 is an unspecified code. G40.901 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, G40.901 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 G40.901 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from G40
The conditions below can never be reported together with G40.901 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 6
The conditions below are not part of G40.901, but a patient may have both at the same time. When documentation supports it, G40.901 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
