Menstrual migraine, intractable, without status migrainosus

This code signifies a severe, debilitating migraine headache that is clearly linked to the menstrual cycle and is resistant to standard acute treatment. The "intractable" designation indicates that the migraine does not respond to usual abortive therapies, but the patient is not experiencing a continuous migraine attack lasting over 72 hours.

Apply this code when documentation explicitly states a diagnosis of menstrual migraine that is difficult to treat or refractory to medication. This diagnosis should be supported by a clear association with the menstrual period and a history of failed acute migraine interventions.

• Ensure documentation specifies "intractable" and explicitly links the migraine to the menstrual cycle.
• Do not use if the patient is in status migrainosus; a different code would be appropriate for that condition.
• Confirm the absence of "without aura" or "with aura" specificity, as this code is for unspecified aura.
