Health insurers in Connecticut have proposed to increase premiums for 2019 by an average of 12.3 percent for Obamacare plans, though there is a wide gap between the requests.

The proposals range from a requested decrease of 10.9 percent by CTCare Benefits Inc. to a requested increase of 31 percent by Anthem Health Plans. Last year, Obamacare plans increased by an average of 25.5 percent.
