ICD-10 Code G43.1 – Migraine with aura (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.1 – Migraine with aura
What it is
Use this code for migraine headaches that include aura, such as visual, sensory, or speech symptoms before or during the headache. It identifies migraine with neurologic warning signs rather than headache without aura.
Clinical signs
Common findings include recurrent headache episodes with reversible aura symptoms, often visual changes, tingling, numbness, or speech disturbance. Clinical features vary; refer to documentation.
When to use this code
Use G43.1 when the provider documents migraine with aura, or clearly describes migraine attacks preceded by aura symptoms. Code it when the record supports the aura diagnosis and no more specific migraine subtype is documented.
If the note only says headache, migraine, or possible aura, check documentation before assigning this code.
Do not use for
Do not use this code for migraine without aura, nonspecific headache, or secondary headache disorders. Check documentation if the aura is not clearly linked to migraine.
Coding tip
Assign the most specific migraine code available, and confirm that aura is explicitly documented before coding G43.1.
