ICD-10 Code G43.111 – Migraine with aura, intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.111 – Migraine with aura, intractable, with status migrainosus
What it is
This code identifies a migraine disorder with aura that is not responding well to treatment and has progressed into status migrainosus. Use it when the record clearly documents all three elements: aura, intractability, and prolonged attack.
Clinical signs
Typical findings include recurrent migraine headache preceded or accompanied by aura, such as visual or sensory neurologic symptoms. Status migrainosus means the attack is unusually prolonged; clinical features vary, so refer to documentation.
When to use this code
Use G43.111 when the provider documents migraine with aura, states it is intractable, and notes status migrainosus. This is appropriate for encounters focused on a prolonged migraine episode or ongoing management of a resistant migraine pattern.
If any part of the description is missing, check documentation before assigning this code. Do not infer aura or intractability from generic migraine wording alone.
Do not use for
Do not use this code for migraine without aura, nonintractable migraine, or migraine episodes not documented as status migrainosus. Check documentation if the record is unclear.
Coding tip
Verify that the provider explicitly links aura, intractability, and status migrainosus before coding G43.111.
