What is this code?

When is it used?

  • May be used when a clinician documents cerebral infarction due to embolism of precerebral arteries in a patient's medical record.

  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
  • This entry may represent a broader category rather than the most specific billable code.
