ICD-10 Code G43.719 – Chronic migraine without aura, intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.719 – Chronic migraine without aura, intractable, without status migrainosus
What it is
This code identifies a chronic migraine pattern without aura that does not respond well to standard treatment. It also specifies that the patient is not currently in status migrainosus.
Clinical signs
Clinical features vary; refer to documentation. Chronic migraine typically involves frequent migraine headaches, often with nausea, light sensitivity, or sound sensitivity, and no aura symptoms are documented.
When to use this code
Use G43.719 when the record clearly states chronic migraine, without aura, and intractable. The provider should document that the condition is not status migrainosus. Check documentation if the note does not specify frequency, aura status, or treatment resistance.
Do not use for
Do not use this code if aura is present, if the migraine is not described as intractable, or if status migrainosus is documented. Use the more specific code that matches the charted diagnosis.
Coding tip
Match all three elements exactly: chronic, without aura, and intractable; otherwise, check documentation for a different migraine code.
