If you need a colonoscopy, should you get the procedure done in the outpatient department of a hospital or at a free-standing surgery center?
The answer for a growing list of medical procedures including colon cancer screening is becoming a big source of controversy for the state's hospitals, an industry that's well represented on the Star Tribune's annual survey of Minnesota's largest nonprofit groups.
Blue Cross and Blue Shield of Minnesota, the state's largest health insurer, last year adopted new rules that steer some patients away from outpatient departments at hospitals for colonoscopy and certain services that the carrier said can be performed at a lower cost in surgery centers. The Minnesota Hospital Association cried foul in response, saying the moves could violate state laws and threaten revenue that hospitals use to subsidize other services.
The trade group asked state regulators to investigate Blue Cross, and those reviews are ongoing. Health insurers across the county, meanwhile, are adopting similar policies for a variety of services, raising a significant financial challenge for hospitals in the process, said Dan Mendelson, the founder and former chief executive at Avalere Health, a consulting firm in Washington, D.C.
"Historically, I do think it's been true that some services have cross-subsidized other services," Mendelson said. "I think that in a world of value-based care, it will become increasingly difficult for hospitals to run those kind of cross-subsidies."
Ambulatory surgical centers are licensed in Minnesota to provide surgical procedures that do not require overnight inpatient hospital care. The centers have been around for decades and have grown as technology improvements, financial pressures and other factors push more medical procedures outside of inpatient hospitals.
The Minnesota Department of Health licenses 81 ambulatory surgery centers. Ownership of the centers is varied — physicians often are involved, but hospitals, health systems, business entities and national groups also have ownership interests. Surgery centers typically have a lower cost structure than hospitals because procedures are scheduled, whereas hospitals run 24/7 and need capacity for unexpected surges.
The new health insurance rules that are pushing procedures into surgery centers, rather than hospital outpatient departments, are known as "site of service" policies.
