Today is the last day individuals can sign up for medical insurance through Vermont Health Connect, the state’s exchange program, and qualify for a subsidy.

After Dec. 23, individuals can continue to use existing insurance plans through March 31, 2014.

For just about everything you wanted to know about the state’s health care exchange, but were afraid to ask, go to VTDigger’s user’s guide to Vermont Health Connect.

The guide includes an interactive chart that helps you find your estimated subsidy level instantly.

Households at or below 400 percent of the Federal Poverty Level qualify for federal subsidies. The state expects to receive $200 million to $400 million in individuals’ health care subsidies from the federal government.

Vermont is the only state that has made purchasing insurance through the exchange mandatory for small businesses and individuals.

Ten days ago, about 20,000 Vermonters who fall under the mandate had not yet enrolled in the insurance program.

At that juncture, the Shumlin administration held a press conference to herald the fact that about 5,000 Vermonters had signed up over a four-day period.

The Vermont Health Connect website has been plagued by delays and glitches since it was launched on Oct. 1.
