Per a study by the Blue Cross and Blue Shield Association, new enrollees under Obamacare "used more medical services across all sites of care-including inpatient hospital admissions, outpatient visits, medical professional services, prescriptions filled and emergency room visits." Obamacare requires health insurers to enroll all applicants regardless of their preexisting conditions and to charge them the same rates as healthy individuals who have been paying insurance premiums for years.
