Code Description

ICD-10 G43.609 is a billable code used to indicate a diagnosis of persistent migraine aura with cerebral infarction, not intractable, without status migrainosus.

Key Diagnostic Point:

Persistent migraine aura with cerebral infarction is a neurological condition characterized by the presence of prolonged aura symptoms that last longer than the typical duration of a migraine aura, which is usually less than 60 minutes. In this case, the aura is associated with cerebral infarction, indicating that there has been an ischemic event in the brain. Patients may experience visual disturbances, sensory changes, or speech difficulties that persist for more than an hour and may be accompanied by headache. This condition is classified as 'not intractable,' meaning that it is manageable and does not lead to continuous or severe migraine attacks. It is crucial to differentiate this condition from status migrainosus, which involves prolonged migraine attacks lasting more than 72 hours. The management of persistent migraine aura with cerebral infarction often involves addressing the underlying vascular risk factors and may include preventive treatments such as beta-blockers, anticonvulsants, or CGRP inhibitors, alongside lifestyle modifications to reduce triggers.

  • Need for detailed documentation of aura symptoms and duration
  • Association with cerebral infarction requiring additional clinical information
  • Potential overlap with other neurological conditions

Audit Risk Factors

  • Inadequate documentation of aura symptoms
  • Failure to document the cerebral infarction diagnosis
  • Misclassification as intractable migraine
  • Lack of evidence for preventive treatment measures

Frequently Asked Questions

What is the difference between G43.609 and G43.001?

G43.609 refers to persistent migraine aura with cerebral infarction that is not intractable, while G43.001 refers to intractable migraine with aura. The key difference lies in the management and duration of symptoms.
