ICD-10 codes for migraine
Migraine specificity depends on aura, intractability, and status migrainosus. The documentation should state whether aura is present and whether the episode is intractable or prolonged.
Notat writes the note — and suggests these codes
The same FactsContext™ engine that extracts codes here turns the full consultation into a structured clinical note, with each code tied to the sentence that supports it. You review and sign every note.
Try AI-assisted extraction with visible medical context
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.

How to use this tool
1
Paste or dictate a de-identified clinical note — a few sentences is enough.
2
Press Get codes. The coding system is fixed on this page.
3
Review each suggested code and its evidence, then copy the codes you agree with.

Paste a clinical note or load an example, then press Get codes. Suggestions appear here with the supporting evidence.
AI suggestions must be reviewed by a clinician before use. Do not paste patient-identifying information into this free tool.

Migraine ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
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 |
How to choose the right code
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.
Documentation example
“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.”
Suggested:
Not direct transcript guessing
FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
Raw facts stay usable
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
Built for review
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.
