What 78494 covers

This study uses a radiotracer in the circulating blood and ECG gating to create tomographic images of the heart across the cardiac cycle. It helps assess ventricular function and wall motion, including left ventricular function monitoring in patients receiving potentially cardiotoxic chemotherapy. Nuclear medicine physicians or other qualified imaging professionals typically perform and interpret the study in hospital or outpatient imaging settings. Unlike myocardial perfusion SPECT, it images the blood pool rather than tracer uptake in heart muscle.

Report 78494 when the documented acquisition is gated equilibrium cardiac blood-pool SPECT. The record should support the cardiac indication, the SPECT blood-pool technique, and the physician’s interpretation. The code has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. CMS applies the cardiovascular diagnostic multiple-procedure reduction to the technical component when the rule applies; it does not reduce the professional component under this rule.
