technical component in hospital billing
It depends. If the hospital employs a on-staff radiologist to read the technical data, then no the hospital would bill globally. If the hospital does not employ a on-staff radiologist, but contracts with a radiologist who bills separately from the hospital then the hospital would bill technical component and the contracted radiologist would bill the professional component.
This rule is true for cardiac testing such as echocardiograms or stress tests. Cardiac testing requires a cardiologist interp just as radiology requires a radiologist interp.
So, just find out if the hospital has a on-staff radiologist or a contracted radiologists.
