ICD-10 Code G43.839 – Menstrual migraine, intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.839 – Menstrual migraine, intractable, without status migrainosus
What it is
This code identifies a migraine linked to the menstrual cycle that does not respond well to usual therapy. It applies when the migraine is documented as intractable and there is no status migrainosus.
Clinical signs
Typical features include recurrent migraine attacks that occur around menstruation, often with headache plus nausea, photophobia, or phonophobia. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states menstrual migraine and the provider documents that it is intractable. It also requires that status migrainosus is not present. If the note only says migraine or menstrual headache, check documentation before assigning this code.
Do not use for
Do not use it for migraine without menstrual association, or for menstrual headaches that are not migraine. Do not select it if status migrainosus is documented.
Coding tip
Verify both the menstrual trigger and the intractable nature in the provider note before coding.
