More than 100,000 Missouri residents have signed up for health insurance through a federally run website during the first month of enrollment.

The figures released Tuesday by the U.S. Department of Health and Human Services show that about half of the Missourians who signed up are new enrollees, and the other half already had coverage through a HealthCare.gov policy.

People faced a Dec. 15 enrollment deadline if they wanted their coverage to kick in when the new year begins Thursday. But people can still sign up for insurance through Feb. 15.

The federal figures show that 102,087 Missouri residents had selected a 2015 coverage plan through HealthCare.gov as of Dec. 15. About 150,000 people got health insurance through the website in 2014.
