Medicare will no longer pay for treating eight specific preventable injuries, infections and errors effective next month. Three more conditions will be added to the list next year.

The particular events include injuries from patient falls, pressure ulcers, urinary-tract infections, vascular-catheter-associated infections, mediastinitis, objects left in the body during surgery, air embolisms, and blood incompatibility.

The government estimates they will save at least $20 million annually because of the changes, which were mandated by a 2005 law.
