Other migraine, intractable, without status migrainosus

This code signifies a type of migraine headache that does not respond to standard treatment (intractable) and is not characterized by a prolonged, severe migraine attack lasting more than 72 hours (without status migrainosus). It encompasses various migraine presentations that don't fit the criteria for common, classic, or complicated migraines, but are persistent and difficult to manage.

Apply this code when documentation clearly indicates a diagnosis of "other migraine" that is explicitly stated as intractable. This is appropriate for patients experiencing chronic or recurrent migraines that have failed multiple therapeutic interventions, but without the extreme severity and duration defining status migrainosus.

• Ensure documentation specifies "intractable" and explicitly rules out "status migrainosus."
• Do not use this code if the migraine is responsive to treatment or if status migrainosus is present.
• Consider co-reporting with codes for associated symptoms or complications if clinically relevant and documented.
