ICD-10 Code G43.50 – Persistent migraine aura without cerebral infarction, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.50 – Persistent migraine aura without cerebral infarction, not intractable
What it is
This code describes a persistent migraine aura that continues after the migraine attack, without evidence of brain infarction. Use it when the record documents ongoing aura symptoms and the migraine is not described as intractable.
Clinical signs
Typical findings include prolonged visual, sensory, or speech-related aura symptoms consistent with migraine. Clinical features vary; refer to documentation, and confirm there is no cerebral infarction.
When to use this code
Use G43.50 when the clinician documents persistent aura after migraine and specifically notes no cerebral infarction. This code also applies when the migraine is not stated to be intractable. If the chart does not clearly support persistence or absence of infarction, check documentation.
Do not use for
Do not use this code for migraine with cerebral infarction or for migraine documented as intractable. Do not assign it when aura is brief or when the record does not support persistence.
Coding tip
Verify both elements in the note: persistent aura and no cerebral infarction.
