ICD-10 Code G43.E0 – Chronic migraine with aura, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.E0 – Chronic migraine with aura, not intractable
What it is
This code identifies a chronic migraine pattern with aura that is not described as intractable. Use it when the record shows migraine headaches with aura occurring on a chronic basis and no documentation of refractory or treatment-resistant disease.
Clinical signs
Typical migraine aura may include reversible visual, sensory, or speech-related symptoms before or with the headache. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic migraine with aura and does not state that it is intractable. It is appropriate for encounters focused on ongoing management, follow-up, or evaluation of recurrent migraine episodes with aura. Check documentation if the chronicity or aura is unclear.
Do not use for
Do not use it for migraine without aura, or when the chart specifically documents intractable migraine. If the type of migraine is not clearly stated, check documentation.
Coding tip
Verify both the chronic migraine diagnosis and the presence of aura before assigning G43.E0.
