ICD-10 Code G43.501 – Persistent migraine aura without cerebral infarction, not intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.501 – Persistent migraine aura without cerebral infarction, not intractable, with status migrainosus
What it is
This code identifies a migraine aura that persists without evidence of cerebral infarction and is not described as intractable. It also indicates the migraine episode meets criteria for status migrainosus.
Clinical signs
Clinical features vary; refer to documentation. Typical migraine aura findings may include visual, sensory, or speech symptoms that continue beyond the usual aura duration, with no stroke or infarction documented.
When to use this code
Use this code when the record clearly documents persistent migraine aura, absence of cerebral infarction, and status migrainosus. You should also confirm the provider did not document intractable migraine.
If the note only says migraine with aura or prolonged headache, check documentation. The code is appropriate when the diagnosis is specifically stated and supported by the clinical record.
Do not use for
Do not use this code for migraine with cerebral infarction, intractable migraine, or nonspecific headache. Check documentation if the aura duration or status migrainosus is not clearly stated.
Coding tip
Verify all three elements—persistent aura, no infarction, and status migrainosus—before assigning G43.501.
