Chronic migraine with aura, intractable, with stat migr

This code signifies a severe and persistent form of chronic migraine, characterized by recurrent headaches occurring on 15 or more days per month for over three months, accompanied by transient focal neurological symptoms (aura). The condition is intractable, meaning it is refractory to standard acute and prophylactic treatments, and has progressed to status migrainosus, a debilitating migraine attack lasting more than 72 hours.

Apply this code when documentation clearly indicates a patient suffers from chronic migraine with associated aura symptoms. The patient's migraine must be explicitly described as intractable to therapy and currently presenting as status migrainosus. Supporting documentation includes physician notes detailing headache frequency, aura presence, treatment failures, and the prolonged, severe nature of the current attack.

• Ensure documentation explicitly states "intractable" and "status migrainosus" in addition to "chronic migraine with aura."
• Do not use this code if the migraine is episodic, without aura, or responsive to treatment.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially for inpatient admissions due to status migrainosus.
