Cleveland-based MetroHealth Medical Center plans to introduce a new point-of service fee, changing the way it charges uninsured patients. The hospital, which is its region’s safety-net health system, said about 37,000 people will be affected by the revamped payment policy. MetroHealth leaders said they expect the new payment system to increase the number of people who get discounted care while at the same time steering those people away from the ER to less expensive forms of service.
