As of today, Medicare will start fining hospitals that have too many patients readmitted within 30 days of discharge due to complications. About two-thirds of the hospitals serving Medicare patients, or some 2,200 facilities, will be hit with penalties averaging around $125,000 per facility this coming year, according to government estimates. Data to assess the penalties have been collected and crunched, and Medicare has shared the results with individual hospitals. Medicare plans to post details online later in October, and people can look up how their community hospitals performed by using the agency's "Hospital Compare" website.
