TLDR; Previous research found that speciality physician owned hospitals (POHs) are treating less Medicare patients that are also healthier and focusing on more profitable patients while still receiving whatever benefits being a Medicare provider gets them. This lead to a blanket restrictions on all POHs in ACA. The above paper compared both specialty and non specialty POHs, which is what ACA actually targets, and found no significant differences between them and non POHs in terms of types of patients, cost of care and outcomes. This suggests that the policy has been too broad and is in need of a revision.
