SPRINGFIELD, Ill. - State officials predicted Tuesday that 95,000 children will sign up for the state's All Kids health insurance plan in its first year, nearly double what they originally expected.

Despite the larger enrollment, the plan's $45 million budget would not have to be increased, state officials said.

"Our budget will more than cover the cost of all of these enrollments," said Kathleen Strand, a spokeswoman for the Department of Healthcare and Family Services. "We had to put a conservative estimate out there. Everything is on track."

Lawmakers greeted the new approximation carefully, with some questioning whether the numbers would add up.

Strand said about 45,000 children has signed up so far. About 40,000 of those will have qualified for obtainable health programs but had never signed up. An additional 5,000 children will not be entitled for any government health care if All Kids didn't exist, she said.

That disparity must shrink as the plan attracts more families who can't afford private insurance but don't qualify for other government plans, she said.
