LINCOLN, Neb. (AP) — Nebraska officials say they’re preparing to implement a state-based insurance exchange if the U.S. Supreme Court upholds President Barack Obama’s health care overhaul.

Republican Sen. Rich Pahls of Omaha says he expects little to change in Nebraska if the high court rejects the law. But a ruling in favor of the law will set up a debate over who controls the mandatory health exchanges, designed as one-stop sites where people in each state can buy health insurance.

Nebraska does not yet have a law setting up a state exchange. But the Department of Insurance has been working on one.

Still, Democratic Sen. Jeremy Nordquist of Omaha says the state hasn’t moved quickly enough. He says officials should hold public hearings to determine how the state should proceed.
