SALEM, Ore. — The director of a new health insurance marketplace for individuals and small businesses says the federal government lobbed "a grenade" into the plan this month.

But Oregon Health Insurance Exchange director Rocky King says he will still deliver a business plan for state lawmakers to consider early next year.

The Obama administration announced this month that it will give states broad leeway to pick the benefits offered under the 2010 health care overhaul. That's good news for Oregon, King says. But it will create a difficult task for planners.

The Statesman Journal reports a preliminary business plan projects that 280,000 Oregonians will get health coverage through the exchange by the end of 2015. The plan estimates that at least 100,000 people will be needed to break even.

An insurance exchange is designed to enable individuals and small businesses to shop for health coverage.
