Migraine w/o aura, intractable, without status migrainosus

This code represents a severe, persistent headache disorder characterized by recurrent, throbbing head pain, often unilateral, without an accompanying aura (e.g., visual disturbances, sensory changes). The migraine is considered intractable, meaning it is difficult to treat or manage, and the patient is not experiencing status migrainosus (a migraine attack lasting longer than 72 hours).

Use this code when documentation clearly indicates a diagnosis of migraine without aura that is resistant to standard treatments. The patient's medical record should specify the intractable nature of the migraine and explicitly rule out status migrainosus. This code is appropriate for chronic migraine sufferers whose condition is difficult to control.

• Ensure documentation explicitly states "intractable" and "without status migrainosus" for accurate code assignment.
• Distinguish from G43.009 (Migraine without aura, not intractable, without status migrainosus) when the condition is responsive to treatment.
• If an aura is present, refer to the G43.1- series for migraine with aura.
