Doctors would actually spend time with patients instead of jumping through hoops for insurance denials. Yes, their staff handles much of it, but there are insurance issues that they end up having to deal with directly, wasting their time.
At my last physical my doctor when on a short rant about insurance. Told me that the reason that there is so much burnout and a high suicide rate among medical professionals isn’t due to their primary job function, helping people become healthier, it was due to having to deal with insurance companies bullshit.
Living in a country with universal health care. Doctors have limited time for each patient. Many people complain about it.
