Hospital ownership of physician practices has grown across the US, and these strategic decisions seem to drive higher prices and spending. Using detailed physician ownership information and a universe of Florida discharge records, we show novel evidence of hospital-physician integration foreclosure effects within outpatient procedure markets. Following hospital acquisition, physicians shift nearly 10% of their Medicare and commercially insured cases away from ambulatory surgery centers (ASCs) to hospital outpatient departments and are up to 18% less likely to use an ASC at all. Distorting physician choices over treatment setting can generate allocative inefficiencies and forgo state and federal tax revenue.
