Reporter Molly Mckenna was in agonizing pain when her fiance rushed her to this austin, texas, Baylor Scott White clinic last january. The doctor came in and said your ovary is a big hemorrhaging mess and we have to take it out. Reporter one of her ovaries was twisting inward cutting off the blood supply. It just got to the point where i could barely even breathe. She was transferred by ambulance to a larger Baylor Scott White for surgery. At each stop staff took her private insurance card.

Reporter mckenna is just one of over 600 people weve heard from in our medical price e financial gamble consumers hts face with medical care. I would be paying less out of pocket if i just had no insurance at all. Reporter Insurance Broker lora everist, who sold mckenna her policy says paying cash would have been cheaper. Nobody told her that she was out of network. Nobody gave her the option to pay cash. Reporter so you basically think that theyre gouging. Absolutely. Reporter because everist says mckennas insurance already paid over 6,000 for the surgery. Mckenna negotiated a few bills down but Baylor Scott White still wants 27,000 more. Because there is no guideline. There is no transparency. They can charge whatever they want. Im not human to them. Im a dollar sign. Reporter Baylor Scott White told us this afternoon its facility charges are lower than other local acutecare hospitals but says this case shows what they call an opportunity for improvement.

Reporter its a new day in some florida schools, like okeechobee high.

Until youre standing in front of someone with a gun pointed at you, you dont realize how helpless you really are. Reporter but critics of Arming Teachers argue Mental Health programs are better strategies. Teachers should concentrate on their primary subject, which is teaching. They include tony montalto, whose daughter gina was one of 17 killed in last years parkland shooting. We should not force them to have to make a choice between staying with the kids that are in their classroom and going out to confront an armed assailant. Reporter its hard to know exactly how many teachers are armed. School districts like the one here in okeechobee do not reveal that information and say for security reasons, the teachers must remain anonymous.
