ICD-10 Code G43.709 – Chronic migraine without aura, not intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.709 – Chronic migraine without aura, not intractable, without status migrainosus
What it is
This code identifies chronic migraine without aura when the headache pattern is not described as intractable and there is no status migrainosus. Use it for a documented chronic migraine diagnosis without aura features.
Clinical signs
Clinical features vary; refer to documentation. Typical migraine findings include recurrent headache episodes with migraine characteristics, but this code applies only when aura is absent and the record supports chronicity.
When to use this code
Use G43.709 when the provider documents chronic migraine without aura and does not state that the condition is intractable. It also fits cases where no status migrainosus is present. If the note is incomplete, check documentation before assigning the code.
Do not use for
Do not use this code if aura is documented, if the migraine is intractable, or if status migrainosus is present. Check documentation for a more specific migraine code when those details appear.
Coding tip
Confirm all three elements—chronic, without aura, and not intractable—before coding, because missing one detail can change the code.
