The U.S. Department of Health and Human Services reports that only 751 Missouri residents selected a health insurance plan through a federally run online marketplace during the first month of its troubled launch. The department said the insurance exchange had about 14,100 completed applications from Missouri from October 1 to November 2. Those applications sought coverage for about 28 thousand people. The federal government did not say how many of the people selecting a health plan had started paying premiums. Nationally, HHS says fewer than 27,000 people signed up for health insurance through the federal exchange.
