Patients have the right to tell you it’s none of your business. And to change doctors.
Changing doctors is getting difficult and will soon be nearly impossible. The best are quietly retiring or heading offshore and what is left will not be nearly enough. The future of American medicine is Clinic Medicine and you get the doctor who is on duty at the clinic your Plan assigns to you. The doctor eventually will be a 4 year graduate of something related to medicine and heavy on Bureaucratic Compliance Studies or will be an upgraded nurse.
That may be true, but have you ever seen your new, "improved" electronic medical records?
Anything you say (or refuse to say) may be entered in there as well as your mental state and attitude toward the doctor and you probably won't know about it. It then goes with you "forever" even if you change doctors.
The potential for abuse by those examining your records for "suitability" to own a firearm or get a CCW is there as you may now have a "mental health" or "anger" issue which is now documented.
