DES MOINES, Iowa — The federal health care law is now in effect, but many Iowa residents are still trying to figure out their new insurance plans or are continuing to seek health coverage.

Jan. 1 marked the first day for many provisions of the new law, including insurance coverage for those who signed up for private plans on the federal enrollment website. Iowa’s modified Medicaid expansion — which uses federal dollars to offer coverage to some low-income Iowans — also started that day.
