ICD-10 Code G43.11 – Migraine with aura, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.11 – Migraine with aura, intractable
What it is
G43.11 identifies migraine with aura that is documented as intractable, meaning the headaches are difficult to control or do not respond well to usual management. Use this code only when both aura and intractability are clearly supported.
Clinical signs
Typical migraine aura may include transient visual, sensory, or speech symptoms before or with the headache. Clinical features vary; refer to documentation, and confirm that the provider describes the migraine as intractable.
When to use this code
Use G43.11 when the record states migraine with aura and the condition is resistant to treatment or otherwise labeled intractable. It is appropriate for encounters focused on ongoing migraine management, persistent symptoms, or evaluation of recurrent attacks with aura.
If the documentation names migraine but does not specify aura or intractability, check the note before coding. You may need a more specific or different migraine code if those elements are absent.
Do not use for
Do not use this code for migraine without aura, or when intractability is not documented. Check documentation if the episode is better described by another headache diagnosis.
Coding tip
Confirm both key terms in the provider note: aura and intractable; if one is missing, do not assume G43.11.
