ICD-10 Code G43.711 – Chronic migraine without aura, intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.711 – Chronic migraine without aura, intractable, with status migrainosus
What it is
This code identifies chronic migraine without aura that does not respond well to treatment and is currently prolonged into status migrainosus. It is used when the chart documents migraine attacks without aura and the status migrainosus complication.
Clinical signs
Typical documentation includes recurrent migraine headaches without aura, frequent enough to meet chronic migraine criteria, plus a prolonged or unusually severe migraine episode. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic migraine without aura, intractable, and status migrainosus in the same encounter. It may also apply when the record clearly supports a prolonged migraine attack in a patient with chronic migraine, and the provider states the condition is not responding to usual therapy.
Do not use for
Do not use this code for migraine with aura, episodic migraine, or a migraine attack without status migrainosus. If intractable status or chronicity is not documented, check documentation.
Coding tip
Code only when all elements are documented: chronic migraine, no aura, intractable, and status migrainosus.
