A few years ago I was in the position of changing doctors and had a very hard time getting my data from my old doctor to the new. I had to constantly go after them to get copies. They kept putting it off and at one point said they owned the records since they prescribed any and everything medical for me. I explained that I owned my records, they may own the paper printed but the information is mine. I bought and paid for the tests and I paid the doctor to decide what tests needed to diagnose my problems and issues. I'm even paying them to keep my records safe by going to them all the time , being my primary care physician. As long as I am a customer of theirs they are happy with keeping my records on file and "lending" out as needed to doctors they refer me to but as soon as I said I was changing doctors (I moved and wanted a closer doctor then the 1.5 hour drive it would now take to get to my old one) they got all up in my face over my records.saying they owned them. After 3 months I finally got my records which really pushed me back 3 months on any medical diagnoses and treatments since the new doctor didn't want to start or stop anything the old doctor told me to do since he didn't have any facts of what my history was at the time. So now any tests I have done I make sure I get a copy for my own records and keep them in my safe at home.
