Similar situation here in my country (middle Europe). There is one big corporate connected to some political representatives. They bought few hospital, 112 ambulance service (equal to 911 service), pharmacies, some local medical centers, they even have one health insurance company (one of three acting here).
They have great diversification. In some locations they have monopoly. If you need immediate help (you see or are member of accident, you have strong pain no matter where (head, teeth, back)) you have almost no choice. You are still calling emergency and/or paying to one pocket.
From one side, public hospital all very old and incredibly indebted, outdated medical devices, buildings are old and need renovation. Mentioned corp invested huge amount of money in renovation, improving environment and business process. People have better services and new private hospitals has very good financial health and level of customer services.
On the other hand, very sad thing is that public representatives are able only talk about nothing and perform reformation feasibility studies and studies about studies. They are not able to get needed public services to desired level. If private corps will own entire public health-care system this will be an issue. Charging for services will not limited at all. There is almost no competition in this area since have huge entry difficulties. And even someone would be able to get into competition with this shark corp. they simply buy him.
