ICD-10 Code G43.609 – Persistent migraine aura with cerebral infarction, not intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.609 – Persistent migraine aura with cerebral infarction, not intractable, without status migrainosus
What it is
This code identifies migraine aura symptoms that persist and are associated with a cerebral infarction. Use it when documentation shows migraine-related aura plus stroke, and the migraine is not described as intractable or status migrainosus.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note persistent focal neurologic aura symptoms with imaging or other evidence of cerebral infarction, along with a migraine diagnosis.
When to use this code
Use this code when the provider documents persistent migraine aura with cerebral infarction and specifically states the migraine is not intractable. It fits cases where the aura continues beyond the usual migraine episode and a cerebral infarct is confirmed. Check documentation if the record does not clearly link the aura and infarction.
Do not use for
Do not use this code for migraine aura without infarction, or for cerebral infarction unrelated to migraine. Also avoid it if the headache is documented as intractable or with status migrainosus.
Coding tip
Confirm both the persistent aura and the infarction are documented together before assigning G43.609.
