At least one health insurance company that plans to sell Obamacare coverage in Iowa is proposing small premium increases, state officials reported Wednesday as they urged voters to pressure congressional action on the healthcare law.

Health Insurers Medica and Wellmark have filed paperwork to sell Obamacare plans in all 99 of Iowa’s counties. The health insurance division would not provide specifics on the rate filings, but did say that Medica’s proposed rate filing was less than 5.6 percent. Last year, it raised rates by more than 50 percent.
