Technical component of a stress echocardiogram: baseline study, stress images and side-by-side comparison of left ventricular wall segments.

What it covers

G582 is the technical component of a stress echocardiography study; the professional component is G583 (J21).

A stress echo must include a baseline study of all components of cardiac structure and function, stress images including relevant peak or immediate post-stress images, and a simultaneous comparison of all left ventricular wall segments and global function before and after stress. Stress may be exercise, drugs or pacing (J21).

• Payable only at a facility with echocardiography accreditation (or provisional recognition) from an MOH-approved body, such as Accreditation Canada Diagnostics (J20).
• You must have Level III or Level II echocardiography training, or interpret at least 400 echo/Doppler studies a year in an established lab plus 24 hours of relevant CME over two years; keep proof for the MOH (J20).
• Must be for an indication in the CorHealth Standards for Provision of Echocardiography in Ontario in effect on the service date (J20).
• Not payable for routine pre-operative preparation or screening unless there is another clinical indication (J20).
