New hospitals and outpatient surgery centers in Oklahoma would have to obtain at least 45% of their gross revenues from Medicaid and Medicare payments under a bill approved in the state House.
The measure passed March 11 by a 51-46 vote is similar to one passed last week by the state Senate.
If the measure becomes law, it may make Oklahoma the first state to mandate a specific payer mix for new institutional providers.
Advocates said it would protect community hospitals from facilities that choose to treat only the most affluent and profitable customers and leave the poor, elderly and expensive.
Opponents said it would stifle competition by prohibiting new specialty centers.
The House bill was modified significantly after an earlier version was rejected in a 56-41 vote.
Existing facilities would not have to meet the requirement nor would hospitals that submitted a letter of intent by Nov. 1.
Kent Webb, president of the Independent Medical Providers Action Coalition, said the bill would halt construction of specialty hospitals.
Stanley Hupfeld, chief executive officer of Integris Health, a growing not-for-profit hospital system based in Oklahoma City, said the bill would level the playing field and protect existing acute-care hospitals.
