I am researching TAVR (Transcatheter Aortic Valve Replacement) procedure and billing for the heart team. Once the TAVR is started and a situation arises that this procedure has to go to open aortc valve replacement to save patients life, how does physician bill for this (or can they bill for this?) The reason I am asking is because this procedure is for patients who are not eligible for open aortic surgery and there is a heart team that is effected. Or does anyone have any suggestions on where to look to get this information? Thanks for any help on this matter!!!
