What 78483 covers

This nuclear cardiology study uses rapid sequential imaging after a radionuclide bolus to capture its passage through the heart. It can provide information about ventricular ejection fraction and wall motion and, when evaluated, right ventricular function or an intracardiac shunt. A nuclear medicine or cardiology imaging team typically performs the acquisition in a hospital or other diagnostic imaging setting, with a qualified physician interpreting the study. Multiple studies may include rest and stress acquisitions, using exercise or pharmacologic stress when performed.

Report 78483 when the service includes multiple first-pass studies; use the single-study code 78481 when only one study is performed. Documentation should identify the number and circumstances of the acquisitions, such as rest or stress, and the findings interpreted. The global service is billed without a component modifier. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.
