Migraine
Chapter 6:Diseases of the nervous system
ICD-10 G43 is a billable code used to indicate a diagnosis of migraine.
Migraine is a primary headache disorder characterized by recurrent episodes of moderate to severe headache, often accompanied by nausea, vomiting, and sensitivity to light and sound. The pain is typically unilateral and pulsating in nature, lasting from 4 to 72 hours if untreated. Migraines can be classified into several types, including migraine without aura, migraine with aura, and chronic migraine. Triggers for migraines can vary widely among individuals and may include stress, hormonal changes, certain foods, environmental factors, and sleep disturbances. The pathophysiology of migraines involves complex neurovascular mechanisms, including the release of inflammatory mediators and changes in cerebral blood flow. Diagnosis is primarily clinical, based on patient history and symptomatology, and may be supported by diagnostic criteria outlined in the International Classification of Headache Disorders (ICHD). Effective management often requires a combination of acute treatments to relieve symptoms and preventive strategies to reduce the frequency and severity of attacks.
