ICD-10 Code G43.61 – Persistent migraine aura with cerebral infarction, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.61 – Persistent migraine aura with cerebral infarction, intractable
What it is
This code identifies migraine aura symptoms that continue with evidence of a cerebral infarction, and the migraine is documented as intractable. Use it when the record links the aura to a stroke-type brain injury.
Clinical signs
Clinical features vary; refer to documentation. Typical records describe migraine aura symptoms that persist beyond the usual episode and imaging or other evaluation showing cerebral infarction.
When to use this code
Use this code when the clinician documents persistent migraine aura with cerebral infarction and states the migraine is intractable. It may appear in neurology notes, discharge summaries, or problem lists when both the aura and infarction are clearly connected. Check documentation if the infarction is not explicitly tied to the migraine.
Do not use for
Do not use this code for ordinary migraine aura without infarction, or for cerebral infarction unrelated to migraine. If the record only says “migraine with aura” or the cause of infarction is unclear, check documentation.
Coding tip
Confirm both elements are documented: persistent aura and cerebral infarction, plus the intractable status.
