Yes that's correct. Sometimes another physician/specialty department (e.g., nuclear medicine) will interpret the myocardial perfusion scan. In that case, the cardiologist would report only the stress test and the second physician would report the interpretation of the myocardial perfusion.so if you have another provider signing off the Nuclear Medicine Myocardial Perfusion Scan, then the cardiologist will not get credit for 78452, correct?
