Chronic migraine with aura, not intractable, with stat migr

This code describes a severe, persistent headache disorder characterized by recurrent migraine attacks with sensory disturbances (aura) that occur 15 or more days per month for over three months. The condition is not resistant to standard treatments and has progressed to a continuous, debilitating migraine attack lasting more than 72 hours.

Use this code when documentation clearly indicates a patient experiences chronic migraines with aura, meaning 15+ headache days per month, with at least 8 of those being migraines, for at least three months. Additionally, the patient must be experiencing status migrainosus, defined as a migraine attack lasting longer than 72 hours, and the condition is not intractable to treatment.

• Always confirm the chronicity (15+ headache days/month for 3+ months) and the presence of aura.
• Ensure documentation explicitly states "status migrainosus" and that the condition is "not intractable."
• Distinguish from G43.E09 (chronic migraine with aura, not intractable, without status migrainosus) based on the duration of the current attack.
