Migraine ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
G43.909 | Migraine, unspecified, not intractable, without status migrainosus | ICD-10-CM |
G43.009 | Migraine without aura, not intractable, without status migrainosus | ICD-10-CM |
G43.109 | Migraine with aura, not intractable, without status migrainosus | ICD-10-CM |
G43.901 | Migraine, unspecified, not intractable, with status migrainosus | ICD-10-CM |
G43.919 | Migraine, unspecified, intractable, without status migrainosus | ICD-10-CM |
Document aura, intractability, and status migrainosus explicitly. Without aura and without intractability/status, G43.009 is more specific than G43.909. Prolonged attacks documented as status migrainosus move to the status variant.
“Recurrent unilateral throbbing headaches with photophobia and nausea, 2-3 per month. No visual aura, no neurological deficit, resolves with sumatriptan. Assessment: migraine without aura, not intractable.”
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
What details make migraine coding specific?
Aura, intractability, and status migrainosus are the key documentation details that drive the G43.- code.
Is G43.909 too vague?
It is valid for unspecified migraine, but if the note states no aura and no intractability, G43.009 is usually more specific.
Can AI detect aura documentation?
Notat extracts aura, duration, associated symptoms, treatment response, and assessment as clinical facts, then suggests the migraine code supported by the text.
