"I'm a complete fan of the Affordable Care Act, but now I can't sleep at night"

“I’m a complete fan of the Affordable Care Act, but now I can’t sleep at night,” Nelson said. “I can’t imagine this is how President Obama wanted it to happen.”

To hold down premiums under the healthcare law, major insurers have sharply cut the number of doctors and hospitals available to patients in the state’s new health insurance market.

Now those limited options are becoming clearer, and California officials say they are receiving more consumer complaints about access to medical providers. State lawmakers are also moving swiftly to ease some of the problems that have arisen.

“It’s a little early for anyone to know how widespread and deep this problem is,” said California Insurance Commissioner Dave Jones. “There are a lot of economic incentives for health insurers to narrow their networks, but if they go too far, people won’t have access to care. Network adequacy will be a big issue in 2014.”
