G43.909 clinical information

Migraines are predominantly a severe recurrent vascular headache, typically presenting as an episodic, often unilateral, moderate to severe pain that is throbbing in nature and worsens with physical activity. This diagnosis falls under episodic and paroxysmal disorders within the broader category of headache syndromes.

Although patients may experience accompanying sensory disturbances—such as nausea, photophobia, and phonophobia—this code excludes persistent migraine aura and is reserved for unspecified migraine without that feature.

Since the condition is not intractable, standard pharmacologic therapy—for example, NSAIDs, triptans, or antiemetics—is typically effective to relieve symptoms and resolve acute episodes.
