Ten health insurers in Connecticut have submitted rate increase requests between 3.6 and 33.8 percent for 14 filings for 2018 individual and small group plans.

Anthem filed a rate of 33.8 percent increase for individual health plans marketed on and off the state's health insurance exchange.
Anthem Health Plans also asked for a rate increase of 31.6 percent on small group health plans for employers with 50 or fewer workers.
ConnectiCare also filed to have a new small group plan that would be marketed through Access Health CT.
Key drivers to the request for an increase in premiums include the cost of prescription drugs, a higher demand for medical services, a deteriorating claims risk pool experience and the return of the federal health insurance tax, which accounts for 2-3 percent of the premium increase, the insurers said in their filings.
"Carriers have filed to take into consideration the perceived lack of strong enforcement of the individual mandate, the lack of stability of the risk adjustment mechanism and the evolving participation of carriers in the market," said Insurance Commissioner Katharine L. Wade.
In rate requests for products not sold through the exchange market, UnitedHealthcare Insurance Company requested an average 3.6 percent increase for small group plans.
Aetna wants an average increase of 19.4 percent for small group indemnity plans off-exchange that provide major medical and prescription drug coverage for employers with 50 or fewer workers.

ConnectiCare also submitted a rate request of 22 percent on individual health plans or solo products, off-exchange.
The carriers have until May 15 to make adjustments. Public hearings will held on June 14.
"In the 2018 rates we are seeing claims experience that reflects increased medical and prescription drug costs along with higher utilization as well as uncertainty in the marketplace," Wade said. "I will continue to work across the Administration and with our Congressional delegation to advocate for market stability for 2018 and beyond to protect Connecticut consumers."
