ICD-10 Code G43.511 – Persistent migraine aura without cerebral infarction, intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.511 – Persistent migraine aura without cerebral infarction, intractable, with status migrainosus
What it is
This code identifies a persistent migraine aura that continues without evidence of cerebral infarction. It also indicates the migraine is intractable and currently meets status migrainosus criteria.
Clinical signs
Typical findings include prolonged aura symptoms such as visual, sensory, or speech changes lasting beyond the usual migraine aura pattern. Clinical features vary; refer to documentation for the persistent aura and status migrainosus details.
When to use this code
Use this code when the record clearly documents persistent migraine aura without cerebral infarction and the provider states the episode is intractable. It also applies when status migrainosus is documented with this specific migraine subtype. You should confirm that no cerebral infarction is reported.
Do not use for
Do not use this code for migraine aura with cerebral infarction or for ordinary migraine aura that has resolved. Check documentation if the chart does not clearly support intractable disease or status migrainosus.
Coding tip
Code the condition only when all elements are explicitly documented: persistent aura, no infarction, intractable, and status migrainosus.
