Migraine without aura, intractable, with status migrainosus

This code describes a severe, persistent migraine attack that occurs without an aura, is resistant to standard treatments, and has lasted for more than 72 hours. It signifies a prolonged and debilitating headache episode that significantly impacts the patient's daily life.

Use this code for patients presenting with a migraine episode that meets the diagnostic criteria for migraine without aura, has failed to respond to acute therapies, and has persisted for over three days. Documentation must clearly indicate the absence of aura, the intractable nature of the migraine, and the duration meeting status migrainosus criteria.

• Ensure documentation explicitly states "without aura" and "intractable" to support this specific code.
• Verify the duration of the migraine episode exceeds 72 hours to meet the "status migrainosus" component.
• Differentiate from G43.001 (migraine without aura, intractable, without status migrainosus) if the duration is less than 72 hours.
