Menstrual migraine, not intractable, with status migrainosus

This code signifies a severe, prolonged migraine attack specifically linked to the menstrual cycle, which has not responded to typical abortive treatments and has persisted for more than 72 hours. The condition is characterized by intense headache, often with associated symptoms like nausea, vomiting, and photophobia, without a return to baseline function between headache phases.

Apply this code when documentation clearly indicates a migraine attack occurring in temporal relation to menstruation, lasting over 72 hours despite treatment efforts, and the patient has not been deemed intractable to therapy. Supporting documentation should specify the menstrual association, the prolonged duration, and the failure of initial treatments.

• Ensure documentation explicitly states "menstrual migraine" and "status migrainosus."
• Distinguish from intractable menstrual migraine (G43.829) where the condition is resistant to all available treatments.
• Do not use if the migraine is not clearly linked to the menstrual cycle or if it has not met the 72-hour duration for status migrainosus.
