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

This code describes a type of migraine where neurological symptoms (aura) persist for more than one week, and imaging confirms a cerebral infarction (stroke) has occurred. The migraine itself is not severe enough to be considered intractable and does not involve status migrainosus. This indicates a permanent neurological deficit linked to the migraine aura.

Use this code when documentation clearly indicates a patient experienced a migraine aura that lasted longer than seven days, and subsequent neuroimaging confirms a cerebral infarction. This diagnosis requires a direct causal link between the persistent aura and the ischemic event. It is appropriate when the migraine is not refractory to treatment and does not meet criteria for status migrainosus.

• Ensure documentation explicitly states "persistent migraine aura" and confirms "cerebral infarction" via imaging.
• Verify the absence of "intractable" or "status migrainosus" in the physician's notes to use this specific code.
• Sequence this code first if the persistent migraine aura with infarction is the primary reason for the encounter.
