Great question. It is very complex, which is part of the problem. Here are  a few examples that you can Google regarding section 6001 of the ACA. "Obamacare Has A Poison Pill For Doctor Owned Hospitals",
" Focus on ACA Compliance for Physician-Owned Hospitals: 5 Key Questions Related to the Expansion Prohibition, The Affordable Care Act (ACA) passed in 2010 has had a profound effect on health care delivery. Specifically, section 6001 of the ACA has sought to limit the expansion of existing physician-owned hospitals, and there has been a moratorium on the construction of new specialty hospitals....The challenges for health care delivery continue. Physician-hospital alignment, especially in specialty care, ultimately results in more efficient coordination of services. The more barriers and layers to physician involvement in our health care systems, the more the cost of health care rises." I'll continue to look for one of the Congressional summaries.  I had a copy but cannot find it.
