ICD-10 Code G43.519 – Persistent migraine aura without cerebral infarction, intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.519 – Persistent migraine aura without cerebral infarction, intractable, without status migrainosus
What it is
This code identifies persistent migraine aura that continues without evidence of cerebral infarction. Use it when the migraine aura is documented as intractable and not occurring with status migrainosus.
Clinical signs
Clinical features vary; refer to documentation. Typical aura findings may include visual, sensory, or speech disturbances that persist beyond the usual migraine aura pattern, with no imaging evidence of infarction.
When to use this code
Use G43.519 when the provider documents persistent migraine aura, specifies that cerebral infarction is absent, and states the condition is intractable. It also applies when status migrainosus is not present. Verify the record supports each element before assigning the code.
Do not use for
Do not use this code if the aura is not persistent, if cerebral infarction is documented, or if the record does not support intractability. Check documentation when the migraine type or complication is unclear.
Coding tip
Confirm all modifiers in the note: persistent, without cerebral infarction, intractable, and without status migrainosus.
