PROVIDENCE, R.I. (AP) — Rhode Island is launching an effort to raise the profile of the online marketplace from which individuals and small businesses will be able to buy health insurance once the federal health care overhaul goes into full effect.

Christine Ferguson, director of the state-run health benefits exchange, said Monday the outreach campaign will include presentations to businesses, community groups and others and will feature radio and TV ads.

About 20 percent in Rhode Island know about the exchange.

Officials also announced the exchange's name, HealthSource RI, and said a call center that will offer consumers help navigating health plan choices will open in September. The state awarded a $24 million, 18-month contract to Florida-based Connextions to run it.

Ferguson expects the exchange will offer 28 plans.
