ICD-10 Code G43.6 – Persistent migraine aura with cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.6 – Persistent migraine aura with cerebral infarction
What it is
This code identifies a migraine disorder with aura that is followed by a cerebral infarction, meaning a stroke-like brain injury occurs in the setting of migraine. Use it when the record clearly links the persistent aura and infarction.
Clinical signs
Typical documentation includes migraine aura symptoms that persist and evidence of cerebral infarction on imaging or specialist assessment. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents persistent migraine aura with confirmed cerebral infarction. It may appear in neurology, stroke, or inpatient notes when the migraine event and infarction are explicitly connected.
Do not assign it for migraine with aura alone, or for a cerebral infarction without documented migraine association. Check documentation if the relationship between the two conditions is unclear.
Do not use for
Do not use for transient aura symptoms without infarction, or for other migraine types without this complication. Do not assume the diagnosis from headache history alone.
Coding tip
Confirm both the persistent aura and the infarction are documented together before coding G43.6.
