What Does “Not Intractable” Mean? “Not intractable” indicates that the migraine responds to treatment and is not resistant to standard medical therapies. This distinction is important for both clinical management and accurate coding. What Is Status Migrainosus? Status migrainosus is a severe migraine attack lasting more than 72 hours. Since G43.909 specifies without status migrainosus, it applies to migraine episodes that do not meet this prolonged duration criteria.
