For a doctor to build a hospital is now a crime.
This makes sense to the pseudo-intellectuals who run our country.
Meanwhile, pretty much every congressman and senator retires as a multi-millionaire. But that’s “doing well by doing good.”
So...
no more Mayo brothers?
That's not exactly true. Building or owning a hospital is not an issue. Referrals are the issue.
The original rules that dealt with physician ownership of hospitals are contained in the Ethics In Patient Referrals Act of 1992 (also called the "Stark Law"). Doctors can build a hospital, but if they refer patients for 'designated health services' at the hospital, they can't submit claims to Medicare or Medicaid for those services without violating the federal False Claims Act.
The Stark Law had exceptions for rural hospitals and specialty hospitals.
That's a little simplistic, but I hope you get my point.
