Menstrual migraine, not intractable, w/o status migrainosus

This code signifies a migraine headache that is specifically associated with the menstrual cycle, but is not severe enough to be considered intractable (difficult to treat) and does not involve status migrainosus (a debilitating migraine lasting more than 72 hours). Patients typically experience these migraines in the perimenstrual period, often without aura.

Use this code when documentation clearly indicates a migraine diagnosis with a direct link to the menstrual cycle. This applies to patients experiencing recurrent migraines that are triggered by hormonal fluctuations, but are responsive to standard treatments and do not meet criteria for intractable or status migrainosus. Physician notes should specify "menstrual migraine" and rule out intractability and status migrainosus.

• Ensure documentation explicitly states "menstrual migraine" and confirms the absence of intractability and status migrainosus.
• Distinguish from G43.821 (intractable menstrual migraine) and G43.820 (menstrual migraine with status migrainosus).
• Consider sequencing with codes for underlying gynecological conditions if relevant, but the migraine code should be primary if it's the reason for the encounter.
