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

This code signifies a chronic neurological condition where a patient experiences migraine aura symptoms (e.g., visual disturbances, sensory changes, speech difficulties) that persist for more than one week, even after the headache phase has resolved or without an associated headache. Importantly, diagnostic imaging has ruled out a stroke or other cerebral infarction as the cause of these persistent symptoms. The condition is also noted as intractable, meaning it is difficult to treat or manage.

Use this code for patients presenting with ongoing migraine aura symptoms that have lasted for at least seven days, where neuroimaging confirms the absence of cerebral infarction. Documentation should clearly state the persistence of aura, the absence of infarction, and the intractable nature of the condition. This code is appropriate when the patient is not experiencing status migrainosus.

• Ensure documentation explicitly states "persistent aura" and "without cerebral infarction" to support this specific code.
• Verify that the patient's condition is documented as "intractable" to differentiate from less severe forms.
• Do not use this code if the patient is in status migrainosus; a different code would be appropriate for that acute, prolonged migraine attack.
