(Philadelphia) -- Some Pennsylvanians who obtain their health insurance through the Affordable Care Act will contend with steep rate hikes and fewer choices as they head into the annual open enrollment period.

An Associated Press analysis of data compiled by Avalere Health shows that some of the 440,000 Pennsylvania consumers who buy insurance through healthcare.gov will face some of the highest premium increases in the nation.

While most exchange consumers in Pennsylvania receive a tax subsidy, about 1 in 4 can expect to pay more for health insurance next year.

Statewide, the average benchmark price will rise by 34 percent. Prices will more than double in a few counties, and go up more than 50 percent in a dozen more.

Insurers are also exiting the market, leaving consumers with fewer choices.
