I have a physician that did performed a Cardiovascular stress test using maximal or submaximal treadmill or bicycle exercise, continuous electrocardiographic monitoring, and/or pharmacological stress; with physician supervision, with interpretation and report CPT code 93015. He want to bill for 93015 twice. 
He thinks that maybe 10% of the time, we initiate a stress test on the treadmill, run through the entire sequence, and the patient cannot get their heart rate to the target. They then convert to a chemical stress test.
Since we have delivered two separate and distinct services, he wants to bill for both (each has a separate report) with a -25 modifier on the second one?
I have told him we can only bill for 93015 once.
Can someone give me feed back on their feelings about this?
Thanks,
AJ
