Reporter these protests have now plunged hong kong into a depth of chaos. The city really has never seen.

Norah. Ramy, thank you for your incredible reporting. An update now in our investigation into medical price roulette which finds americans are paying a wide range of cost for the same medical procedures weme house cost and asked you, our viewers, what you paid for tests and procedures and we heard from hundreds of you, thank you. And tonight anna werner has a story to which we can all relate. I thought i was dying. It was really scary. 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. A few weeks later she was told much of her treatment was out of network. The amount she owed . More than 40,000. I mean, what is that like for you . I remember crying. I was very upset. 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. They now say theyll be contacting Molly Mckenna to help solve this, norah. Anna, the question everybody has is what do you do then in an emergency situation . Reporter right. So, a few things. Find out which hospitals are in your network that are close to you. Find out now. Way ahead of time. Reporter if its not a life threatening emergency consider a walkin or urgentcare clinic which should be cheaper. When the bill arrives try to negotiate. By the way, to share your prices you can go to cbsnews. Com healthcosts. Share what you paid with us. I might log on myself.

This certainly bears the fingerprints of humancaused climate change, making these heat waves more extreme now, and theyre likely to get more extreme in the future. Reporter we interviewed him in central park, which could hit 90 degrees tomorrow for the first time in october since 1941. The heat is scorching the south, which is battling a cropkilling drought. And in columbus, ohio, where ron ross works in construction, the mercury hit a recordsetting 94 degrees today. I feel like we might be hotter than florida. But theres no beaches here.

Reporter its a new day in some florida schools, like okeechobee high. The district here is one of 11 that have adopted a policy that allows trained teachers to carry concealed guns into the classroom. We spoke with parents. I think its good.

Reporter incredibly he missed and was shot by a Security Guard before taking his own life. 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. Its worth noting the states Largest School districts are not participating. Norah. All right, manny, thank you.

Mountain, a team of Italian Government scientists are pouring over the data, which is also coming from drones and satellites. You see the difference between yesterday and today. You see where all the ice fills up here. Reporter Jean Pierre Fasson explained how rapid melting caused by warmer temperatures is making the glacier slide. And in glacier speak, its speeding 24 inches per day. Its a lot. For a glacier, its a lot. Reporter fasson is in charge of mountain safety in this area which includes the picturesque Tourist Destination of courmayeur, where folks are not in danger but are watching closely. When do you think this might happen . You have to call god because you cannot say when it falls. Reporter but fasson says the culprit is clear. Climate change. The great problem for the glacier is not one day of high temperatures. Instead, is the continuous of high temperatures night and day. Reporter up here on mont blanc at an elevation of more than 11,000 feet, we got a closer look at these glaciers. Massive frozen rivers of ice. There are about 30 glaciers here on the italian side of mont blanc and all of them are melting. In fact, in the last 50 years, italian glaciers have lost about 40 of their mass, and this is a global problem. Melting glaciers have led saearing ice sheets.
