Code Description

ICD-10 G43.839 is a billable code used to indicate a diagnosis of menstrual migraine, intractable, without status migrainosus.

Key Diagnostic Point:

Menstrual migraine is a type of migraine headache that is closely linked to the menstrual cycle, typically occurring in women during the luteal phase of their cycle. The intractable nature of this condition indicates that the migraines are resistant to standard treatment protocols, leading to significant disability and impairment in daily functioning. Patients may experience severe, unilateral throbbing pain, often accompanied by nausea, vomiting, and sensitivity to light and sound. Unlike status migrainosus, which is characterized by a prolonged migraine attack lasting more than 72 hours, intractable menstrual migraines can occur episodically but are difficult to manage effectively. Triggers may include hormonal fluctuations, stress, dietary factors, and environmental changes. Preventive treatments often involve hormonal therapies, such as oral contraceptives, and medications like beta-blockers or anticonvulsants. Understanding the unique characteristics of menstrual migraines is crucial for effective management and coding.
