Migraine w/o aura, not intractable, with status migrainosus

This code signifies a severe, prolonged migraine attack that occurs without an aura and is resistant to standard outpatient treatments. The patient experiences a continuous migraine lasting more than 72 hours, often requiring hospitalization for symptom management. It represents a significant escalation in migraine severity and refractoriness.

Apply this code when documentation clearly indicates a patient presenting with a migraine lacking an aura, which has persisted for over 72 hours despite initial interventions. This diagnosis is typically made in an emergency department or inpatient setting when the patient's migraine has become debilitating and unresponsive to usual abortive therapies.

• Ensure documentation explicitly states "without aura" and "status migrainosus" to support this specific code.
• Do not use this code if the migraine is described as intractable but not meeting the 72-hour duration for status migrainosus.
• Consider sequencing this code as the primary diagnosis when the status migrainosus is the reason for the encounter.
