ICD-10 Code G43.011 – Migraine without aura, intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.011 – Migraine without aura, intractable, with status migrainosus
What it is
This code identifies a migraine attack without aura that does not respond well to treatment and has progressed to status migrainosus. It reflects a prolonged, severe migraine episode rather than a routine headache.
Clinical signs
Typical findings include migraine pain with associated features such as nausea, vomiting, and sensitivity to light or sound. Clinical features vary; refer to documentation for evidence that the episode is prolonged and intractable.
When to use this code
Use this code when the record clearly states migraine without aura, intractable, and status migrainosus. The documentation should show a prolonged migraine episode and that standard therapy has not relieved it. If any element is missing, check documentation before assigning the code.
Do not use for
Do not use this code for migraine with aura, nonintractable migraine, or a simple recurrent headache. It is also not appropriate when status migrainosus is not documented.
Coding tip
Code only when the provider documents all three elements: without aura, intractable, and status migrainosus.
