ICD-10 Code G43.801 – Other migraine, not intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.801 – Other migraine, not intractable, with status migrainosus
What it is
This code identifies a migraine that does not respond to treatment in a chronic, prolonged attack lasting more than 72 hours. It is used when the migraine type is documented as other migraine and status migrainosus is present.
Clinical signs
Patients typically have a severe migraine headache with associated features such as nausea, vomiting, or sensitivity to light or sound. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states other migraine and status migrainosus, and the migraine is not described as intractable. You should code it for prolonged migraine attacks that meet the documented status migrainosus diagnosis. Check documentation if the migraine subtype is unclear.
Do not use for
Do not use this code if the migraine is documented as intractable or if status migrainosus is not mentioned. Do not assign it for nonspecific headache or for migraine types documented elsewhere.
Coding tip
Verify both the migraine subtype and the “not intractable” wording before assigning G43.801.
