Other migraine, not intractable, with status migrainosus

This code signifies a migraine headache that does not fit the criteria for a common or classic migraine, is not resistant to standard treatment, and has persisted for more than 72 hours. It describes a severe, prolonged migraine attack that is debilitating and often requires acute medical intervention.

Use this code when documentation clearly indicates a prolonged migraine episode (over 72 hours) that is not intractable and is not specified as a migraine with or without aura. Supporting documentation should detail the duration of the migraine and the lack of response to initial abortive therapies, without indicating intractability.

• Differentiate from intractable migraines (G43.809) where treatment has failed to provide relief.
• Ensure the "other migraine" classification is supported, meaning it doesn't fit G43.0-G43.7 categories.
• Verify the migraine duration exceeds 72 hours to meet the "status migrainosus" criteria.
