Add-on technical fee for using an ultrasound contrast agent with a complete (G570) or stress (G582) echocardiogram in a difficult-to-image patient.

What it covers

G585 is the technical component for echocardiography with a contrast agent, added to G570 or G582 (J23).

It is only for difficult-to-image patients, where two or more contiguous segments weren't seen on recent non-contrast images (J23).

Billing rules

• Only with a complete study or stress study, when two or more contiguous segments weren't seen on recent non-contrast echo images (J23).
• The agent must be bubble-based, 5 microns or less, resonate in the diagnostic ultrasound range and cross the pulmonary circulation (J23).
• The professional component (G571 or G583) must be payable for the same study (J23).
• You need Level III training with contrast experience, or Level II plus contrast training, or the pre-1990 practice criteria on J23–J24; keep proof for the ministry (J23, J24).
• Keep a permanent dynamic record of the images and loops (J24).
• The technical component is not payable for hospital in-patients, or when the patient is admitted to the same hospital for the same condition within 24 hours; in a hospital it pays 86.10% of the listed fee (GP11).
