There are a few things to keep an eye on as the health care reform law enters its second year — if it survives the Supreme Court, that is. First, will enough states be far enough along with their health insurance exchanges? Health and Human Services will create a federal exchange for any state not ready by January 2013. Next, the HHS must put out a formal rule on how states will determine the package of “essential health benefits” — the minimum benefits health plans will have to cover. At some point, providers will apply to become accountable care organizations, the networks of hospitals and doctors that will work together to deliver more efficient care. Perhaps most interesting of all: will House Republicans have a replacement plan ready by the Supreme Court’s expected ruling in June?
