Other migraine, intractable, with status migrainosus

This code signifies a severe and persistent migraine headache that does not respond to standard acute treatments (intractable) and has progressed to a debilitating state lasting more than 72 hours, often with only brief periods of relief. It represents a prolonged and severe migraine attack distinct from typical migraine episodes.

Use this code when documentation clearly indicates a diagnosis of "other migraine" (not specified as common, classic, or complicated) that is intractable and has evolved into status migrainosus. This typically involves a patient presenting with continuous or near-continuous migraine symptoms for over three days despite therapeutic interventions.

• Ensure documentation explicitly states "intractable" and "status migrainosus" in addition to "other migraine."
• Distinguish from other migraine types (e.g., G43.0-G43.7) that may also be intractable but have not reached status migrainosus.
• Do not use if the migraine is responsive to treatment or if the duration is less than 72 hours.
