Iowa received a $1 million grant this week to support its transition to a state-based health insurance marketplace by 2016.

In addition to the District of Columbia, other states receiving a total of $188 million in funds from the Centers for Medicare and Medicaid Services, or CMS, are: Arkansas, Connecticut, Idaho, Rhode Island and Minnesota.

Both Arkansas and Iowa have what is called a "federal partnership" with the health insurance marketplace. The other states that received the grants, as well as Washington, D.C., all operate with state-based health insurance marketplaces.

Iowa is expected to eventually transition to a state-based exchange. In the meantime, the $1 million will be used to prepare for that and to support the federal/state connection with the Medicaid eligibility system, said Amy McCoy, a spokeswoman for the Iowa Department of Human Services, or DHS.

The Iowa DHS was the lead agency for the grant. It is the fourth time Iowa has received this type of federal grant.
