Enrollment through Connecticut’s health insurance exchange has increased to 126,653, according to officials at Access Health CT.

Of those, 53,673 individuals have chosen plans with one of the three private insurance carriers and 72,980 individuals enrolled in Medicaid between Oct. 1 and Feb. 18. That means about 4,670 individuals enrolled between Feb. 10 and Feb. 18.

Officials at Access Health CT are attributing the bump in enrollment to an advertising campaign they’ve been running during the Olympics. Compared with the week prior to the Olympics, the exchange saw a 31 percent increase in web traffic, a 24 percent increase in account creation, an 8 percent increase in call volume, and a 67 percent increase in daily enrollment.

Enrollment in the exchange is open until March 31.

In January, some members of Access Health CT’s expressed concern about the demographic information of those signing up for one of the three private insurance carriers.

A month later, not much has changed.

Individuals enrolling between the ages of 55 to 64 dropped two percent, while those ages 26 to 44 was up one percent to 25 percent. Those ages 45 to 54 increase one percent since Jan. 15.
