The increased revenues are because they are getting more patients that use Medical, not because they are getting more money per patient.
Sutter Auburn is receiving more money
per inpatient case than they were prior to the Hospital Value-Based Purchasing program.
Hospitals get paid by Medicare under the inpatient prospective payment system, which assigns a certain dollar amount to every inpatient case they see.
Under the value-based purchasing program, each of those dollar amounts gets multiplied by a (small) adjustment factor whose value depends on the quality of the care the hospital provides. So for FY13, everything Sutter Auburn billed Medicare was multiplied by a factor of 1.004078237 (or, as KHN said, each of their payments was increased by 0.41%). They're a relatively high performer, so all of their reimbursements got a little bump.
