Rate filings indicate some of the 85,000 people who bought private health insurance plans through Kentucky's exchange could have to pay more for those plans in 2015.
But state officials warned the complex math and federal subsidies involved in setting health insurance premiums on the exchange make it impossible to say how the rates will impact people.
Rates for the Kentucky Health Cooperative could increase an average of 20 percent next year while rates for Humana will increase an average of 12.8 percent. Rates for Anthem Blue Cross Blue Shield will decrease by an average of 4.3 percent.
Republican Senator Mitch McConnell has vowed to repeal the health law, while Democratic challenger Alison Lundergan Grimes says she wants to fix it.
