Migraine without aura
ICD-10 G43.0 is a billable code used to indicate a diagnosis of migraine without aura.
Migraine without aura is a common type of headache disorder characterized by recurrent episodes of moderate to severe headache, typically unilateral, pulsating in quality, and often accompanied by nausea, vomiting, and sensitivity to light and sound. Unlike migraine with aura, patients do not experience transient neurological symptoms prior to the headache onset. The International Classification of Headache Disorders (ICHD) defines this condition as having at least five attacks fulfilling specific criteria, including headache lasting 4 to 72 hours, and the presence of at least two of the following features: unilateral location, pulsating quality, moderate to severe intensity, and aggravation by routine physical activity. Triggers for migraine without aura can include stress, hormonal changes, certain foods, and environmental factors. Preventive treatments may involve lifestyle modifications, pharmacological interventions such as beta-blockers, anticonvulsants, and antidepressants, and the use of CGRP inhibitors. Accurate diagnosis and coding are essential for effective management and treatment planning.
