The U.S. government has issued a proposal that would likely increase risk payments in 2014 to health insurers offering plans on the Obamacare exchanges after the companies complained a recent policy change allowing people to keep their insurance policies had changed the financial equation.

The rule, published on Monday in the Federal Register, lowered the threshold at which risk payments kick in for the sickest health plan members. The government proposed paying insurers 80 percent of claims greater than $45,000 in 2014. Previously the lower limit was $60,000.

There is a 30-day comment period for the proposed rule.
