Chronic migraine with aura, intractable, without stat migr

This code signifies a persistent, long-standing migraine disorder characterized by recurrent headaches preceded or accompanied by transient neurological symptoms (aura), which has proven resistant to standard treatments. The condition is considered intractable, meaning it is difficult to manage or cure, but the patient is not experiencing a prolonged, severe migraine attack (status migrainosus).

Utilize this code for patients diagnosed with chronic migraine who consistently experience aura and whose condition has been documented as refractory to multiple therapeutic interventions. Documentation should clearly state "chronic migraine with aura," "intractable," and explicitly rule out "status migrainosus."

• Ensure documentation specifies both "chronic" and "intractable" for accurate code assignment.
• Distinguish from other migraine codes by carefully reviewing whether aura is present and if the condition is intractable or in status migrainosus.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
