Maps illustrate how premiums in Affordable Care Act (ACA) marketplaces changed for 2018 by looking at the change in the lowest-cost bronze, silver and gold plans by county; counties where an individual’s tax credit covers the full premium of the lowest-cost bronze plan; and counties where the unsubsidized premium for the lowest-cost gold plan has a lower or comparable premium to the lowest-cost silver plan in 2018.
As Open Enrollment for 2018 coverage gets underway, consumers who have health coverage through the Affordable Care Act (ACA) Marketplace are again receiving renewal notices from their health insurers.

That is because renewal notices sent by insurers are required to inform consumers what their 2018 monthly premium will be, assuming they receive the same amount of advanced premium tax credit (APTC) next year that they did in 2017. Insurer renewal notices have been required to present information this way since 2014.
