What 78430 covers
This cardiac imaging study uses positron emission tomography to evaluate the myocardium at rest and under stress, with CT imaging acquired as part of the service. It is reported for a combined rest-and-stress PET examination. Imaging staff perform the technical acquisition, and a physician may report the professional interpretation.
Medicare assigns this code physician fee schedule status C, or carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service has professional and technical components. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and reporting the code without either modifier represents the global service. This is the rest-and-stress study, distinct from a single-study PET service.
