Some Wisconsin health insurers say higher deductibles and less coverage will result from the lower premiums touted by Republicans in their Obamacare replacement bill. Cathy Mahaffey, C-E-O of the Common Ground Cooperative in Brookfield, says that if people are serious about cutting insurance costs, “We’ve got to start talking about the cost of medical care.” House leaders expect the Senate to give higher tax credits to older people to cover expected price increases for them. Still, Marty Anderson of Marshfield’s Security Health Plan says the age makeup for its plans will change “dramatically” as fewer people above 50 would pay for coverage. The House is scheduled to start debating the G-O-P’s health bill tomorrow (Thursday) — but Wisconsin Senate Republican Ron Johnson says he has “lots of problems” with the current package, and he’s not confident that a bill could pass this year.
