Hospitalist monitoring a Nuclear Stress Test

I have a hopitalist that monitors the patient BEFORE the Nuclear stress. He takes vitals and is there when the injection takes place. He is also "available" while test is happening, in case of complications with the patient. This is not a standard Stress test, so 93016 would not apply. Would this be just a regular hospital visit? Any help would be greatly appreciated.

the hospital should pay him

there is no code for this- in fact the cardiologist who reads the EKG portion and bills for that service is responsible for the patient and should be supervising it.
