DENVER (AP) – Filings with the Colorado Division of Insurance indicate the monthly cost of health insurance bought through the state’s exchange is expected to drop an average of 1.4% next year. Officials say a lot depends on where someone lives. For example, residents in some counties on the Eastern Plains will see 12% increases in their monthly premiums, while Park County residents could pay 12% less, on average. State officials estimate premiums will be almost 21% lower than they would have been without the reinsurance program, which reimburses insurers some of the cost of covering customers with higher medical bills.
