Um, it is incredibly common for IC to try and bill themselves as surgeons. Is it the majority? Probably not. But 20%+, wouldn't be surprised. I certainly don't have the experience that
@Winged Scapula does, but I think that it is far more concentrated over my 7 years because in vascular we interface more heavily with cardiology. But, in my experience it is a weekly occurrence. I understand why it happens. It is often very difficult for all of us to describe our exact role and make it map to and correspond to our titles. For example, cardiologist refers patient to his IC buddy who then doesn't feel comfortable with the intervention because it is more complex than they typically deal with, so they send to their other IC buddy who then either can't deal with it or ****s it up, then the patient ends up in front of CT surgery or vascular surgery. All of a sudden the patient has to understand/rationalize four different physicians seeing them for the same issue. There IS a logical progression to it, but at the end of the day the nuances dividing each of those providers is difficult for people to comprehend and there is a temptation for some to dumb it down to the point of saying that they are surgeons because they think patients will understand better. It happens several times a year where I have to explain to a patient that they haven't seen a surgeon yet, despite them insisting otherwise.
This is hardly unique to cardiology. People do this all over the place, both in medicine and outside of it. For example, over the weekend I had a friend (And IR fellow) trying to convince me to learn how to do kyphoplasties and join them in practice. Why? Because it generates 200+ RVUs for 20 minutes of work. If I started doing that in private practice, I can't really bill myself as a vascular surgeon to patients because it doesn't make logical sense, despite having a skillset that is very easily adaptable to the procedure itself. I would need to find a different way of describing myself to patients as well as referring docs.
