  OTHER TERMS AND DEFINITIONS
    1. Professional and technical components are claimed separately. Claims for technical component
       H are submitted using listed fee code with suffix B. Claims for professional component P are
       submitted using listed fee code with suffix C.
                   2. For services rendered outside a hospital setting (except for J301, J304, J324, and J327) the
                      only fees billable under the Health Insurance Act are listed under the column P (use suffix C).
                      Costs for the technical component of services rendered in an ICHSC are listed in the Schedule
                      of Facility Costs.
                   3. Each of the following tests designated by an individual code number is considered to be specific
                      and requires individual ordering.
                   4. Exercise assessment (J315, E450, E451, J316) requires a physician to be in attendance at all
                      times.
                   5. The technical and professional fee components for pulmonary function studies are not eligible
                      for payment in the routine preoperative preparation or screening of a patient for non-thoracic
                      surgery unless required for respiratory diagnosis, anaesthetic decision making or optimization
                      of a patient's respiratory disease prior to surgery.
