Seven states have told the U.S. Department of Health and Human Services (HHS) that they want to share control over health insurance exchange (HIX) programs in their jurisdictions with HHS.
Another 16 states and the District of Columbia are hoping to run a total of 17 exchanges, and HHS itself seems to be on track to oversee 27 exchanges.
Analysts at Avalere Health have published those figures in a report based on a review of state exchange filings.
The final application deadline for states that want to set up partnership exchanges together with HHS was Friday.
States that hope to run their own, state-based exchanges were supposed to notify HHS earlier.
The states that have applied to work with HHS to run partnership exchanges are Arkansas, Delaware, Illinois, Iowa, Michigan, New Hampshire and West Virginia.
Those states could enroll a total of about 722,000 residents through exchange-based health insurance plans in 2014, Avalere analysts said.
That enrollment projection includes enrollment in Medicaid and Children's Health Insurance Program (CHIP) plans as well as exchange-based commercial plans.
Avalere analysts reported that officials in three states -- Ohio, Utah and Virgina -- hope to let HHS set up exchanges for their residents but retain some local control.
Utah wants to run its small business exchange.
Ohio and Virginia want to control reviews and certifications of the plans sold through the federal exchanges in their states.
