ICD-10 Code G43.119 – Migraine with aura, intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.119 – Migraine with aura, intractable, without status migrainosus
What it is
This code identifies migraine with aura that does not respond well to treatment and is not accompanied by status migrainosus. The aura is a reversible neurologic symptom that occurs before or with the headache.
Clinical signs
Typical features include recurrent migraine attacks with visual, sensory, or speech-related aura symptoms. Clinical features vary; refer to documentation for the specific aura pattern and whether the migraine is documented as intractable.
When to use this code
Use this code when the provider documents migraine with aura and states that it is intractable or refractory. It also applies when the record clearly shows no status migrainosus is present. Check documentation if the note only says “migraine” or does not specify aura.
Do not use for
Do not use this code for migraine without aura, or for attacks documented as status migrainosus. If the record does not confirm intractability, choose the more specific documented migraine code.
Coding tip
Assign G43.119 only when both aura and intractability are explicitly documented.
