Perst migraine aura w/o cereb infrc, not ntrct, w stat migr

This code describes a type of migraine where the patient experiences neurological symptoms (aura) that persist for more than one week, but without evidence of a stroke or other brain injury. The migraine attack itself is prolonged and severe, lasting over 72 hours, and is not responsive to initial treatments. The condition is not considered intractable, meaning it is not resistant to all forms of treatment.

Apply this code when documentation clearly indicates a patient is experiencing persistent migraine aura without cerebral infarction, and the migraine has progressed to status migrainosus. This diagnosis requires the absence of a stroke confirmed by imaging and the prolonged, severe nature of the migraine attack.

• Ensure documentation explicitly states "without cerebral infarction" to differentiate from G43.51-.
• Confirm the migraine attack meets the criteria for status migrainosus (lasting >72 hours) and is not intractable.
• Do not use this code if the aura is transient or if there is evidence of a stroke.
