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

This code signifies a complex migraine presentation where a patient experiences a persistent aura, meaning the neurological symptoms (e.g., visual disturbances, sensory changes) continue for an extended period, often weeks or months, after the headache phase has resolved. Crucially, this persistent aura is associated with evidence of a cerebral infarction (stroke) and is considered intractable, meaning it is difficult to treat.

Use this code when documentation clearly indicates a patient has a persistent migraine aura, confirmed by imaging to be linked to a cerebral infarction. The patient's condition must also be described as intractable, implying resistance to standard treatments. This code is appropriate for cases where the migraine aura is ongoing and not in a state of status migrainosus.

• Ensure documentation explicitly states "persistent aura" and "cerebral infarction" in the context of migraine.
• Verify that the condition is described as "intractable" and not "with status migrainosus" to avoid miscoding.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated neurological deficits from the infarction.
