ICD-10 Code G43.E – Chronic migraine with aura (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.E – Chronic migraine with aura
What it is
This code identifies chronic migraine in which aura occurs with the migraine pattern. Use it when the record documents both frequent migraine headaches and aura symptoms, such as visual or sensory changes.
Clinical signs
Typical findings include recurrent headache episodes with migraine features and aura preceding or accompanying attacks. Clinical features vary; refer to documentation for the specific aura type and frequency pattern.
When to use this code
Use G43.E when the provider clearly documents chronic migraine with aura, not just a history of migraine. It is appropriate when the note links ongoing migraine episodes to aura symptoms and supports the chronic pattern. Check documentation if the record does not specify aura.
Do not use for
Do not use this code for migraine without aura or for isolated aura symptoms without migraine. If the chart only says “migraine” or is unclear about chronicity, check documentation before coding.
Coding tip
Code only when both chronic migraine and aura are explicitly documented in the same clinical context.
