Can we code the microscope (69990) with 35301, carotid endarterectomy?
CPT does not list 35301 as inclusive of the microscope (+69990); therefore, the microscope can be coded assuming documentation criteria is met. That said, Medicare considers the microscope bundled into 35301 and will not reimburse it. Other payors may or may not follow Medicare’s payment rule.
