G40.89 is the authoritative medical code for Other seizures. This classification is used in medical billing and clinical recording to specify the clinical criteria for other seizures (ICD-10-CM G40.89), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Frequently Asked Questions (FAQ) & Clinical Guidance
What can't be coded together with G40.89?
Per Excludes1 instructions, G40.89 must not be reported with: post traumatic seizures (R56.1); recurrent seizures NOS (G40.909); seizure NOS (R56.9); conversion disorder with seizures (F44.5).
Can G40.89 be reported alongside related conditions?
Per Excludes2 instructions, G40.89 and the following may both be reported when both are present: hippocampal sclerosis (G93.81); mesial temporal sclerosis (G93.81); temporal sclerosis (G93.81); Todd's paralysis (G83.84).
