I find this very disturbing in several ways. First, that people believe it. Second that a US Senator embraces such rhetoric.
Any insurance company that had a policy of denying legitimate claim payment would not be in business very long. And no insurer denies care.
Do insurers deny claims? Of course, for a variety of reasons, including mistakes by the insurers staff and sometimes by the hospital or physician’s staff. Sometimes because a treatment is questionable or outside guidelines (despite what an individual physician may say). Sometimes a service is simply not covered and sometimes the service is still considered experimental in nature.
But here’s the thing, none of that will change under a universal system, Medicare for All or otherwise. No system can write a blank check for health care. Medicare wastes billions each year to fraud in large part because it does not do sufficient claims review.
To imply that Medicare for All will simply pay for any and all services ordered by “your” doctor in any setting for any reason, no questions asked is ignorant and assumes you are too.
