Perst migraine aura w cerebral infrc, ntrct, w stat migr

This code signifies a severe and prolonged migraine aura that persists for more than one week, accompanied by evidence of a cerebral infarction (stroke) attributable to the migraine. The migraine itself is intractable, meaning it is resistant to standard treatment, and has progressed to status migrainosus, a debilitating migraine attack lasting 72 hours or longer.

Apply this code when documentation clearly indicates a patient experiencing a persistent migraine aura with objective evidence of an associated ischemic stroke. The medical record must also specify that the migraine is intractable and has evolved into status migrainosus. This code is typically used in inpatient or emergency department settings for patients with acute, severe neurological events.

• Ensure documentation explicitly links the cerebral infarction to the persistent migraine aura.
• Verify that both "intractable" and "status migrainosus" are clearly stated in the physician's notes.
• Sequence this code first as the primary diagnosis when it is the reason for the encounter, followed by codes for specific stroke sequelae if applicable.
