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.
