HELENA, Mont. (AP) — More than 36,500 people in Montana signed up for insurance through the online marketplace central to the health care overhaul law, and now state officials will try to figure out how many more enrolled without using the exchange and how many were previously uninsured.

The 36,584 Montanans who selected plans through the federal exchange by the end of the open-enrollment period exceeded federal health officials’ original target of 31,000, according to data released Thursday by the U.S Department of Health and Human Services. The figures include people allowed to sign up during a two-week extension because they had started their applications before the March 31 deadline expired.
