State-run reinsurance programs lowered health insurance premiums by nearly 20 percent, according to a study released Wednesday that will aid Democrats seeking added funding for a federal reinsurance pool.

“For states looking to stabilize their individual markets, reinsurance programs may be an attractive opportunity,” said Chris Sloan, associate principal at Avalere Health, the consulting group that released the study. “State-based reinsurance programs have the potential to reduce premiums and are a good financial deal for states if they can identify a source of funding.”
