ICD-10 Code G43.101 – Migraine with aura, not intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.101 – Migraine with aura, not intractable, with status migrainosus
What it is
This code identifies a migraine disorder with aura that is not documented as intractable and is complicated by status migrainosus. It tells you the headache episode is prolonged and severe, beyond a typical migraine attack.
Clinical signs
Expect a migraine pattern with aura symptoms such as visual, sensory, or speech changes before or during the headache. Status migrainosus means the migraine attack persists for an extended period and is clinically significant; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents migraine with aura and explicitly states status migrainosus, without describing the condition as intractable. It fits encounters where the prolonged migraine episode is the reason for evaluation, monitoring, or ongoing management. Confirm the aura and status terms in the note.
Do not use for
Do not use this code if the migraine is documented as intractable, because that changes the code selection. Do not assign it for headache without migraine, or when status migrainosus and aura are not clearly documented. Check documentation.
Coding tip
Verify both aura and status migrainosus are stated together, and confirm the note does not also describe the migraine as intractable.
