Is it true that medicare can deny coverage if you leave a hospital against medical advice?

Myth. . Unfortunately, this one of these myths perpetuated in medical culture. I have heard physicians and discharge planners say it, and thought it to be true as well (at least for some private insurers). A study done at least for er visits, show that this is false: http://tinyurl.Com/7aq5bmg. If a doctor deems that it's not medically necessary for you to be inpatient, then medicare can deny coverage.
