MARK STRASSMAN (REPORTER): Dr. Greg Mitchell practices family medicine in West Tennessee. Two-thirds of his patients use Medicaid. STRASSMAN: You see patients from how far away? DR. GREG MITCHELL: From about up to 90 miles away you have to travel for services here to come to our hospital system and our clinic. STASSMAN: Because their hospitals have closed. MITCHELL: Yes sir.
