since you have employer coverage it is up to your employer what plans are being offered. it is true however that in most states there are one or two dominant insurers in both the individual and small employer market. one of the goals of the aca is to try to increase the number of options available for people who shop through the marketplace. unfortunately that goal was not reached in all areas at least for 2014.
i'm a north carolina resident/employee that has employer provided single health insurance coverage for 2014. i will return to the group plan in 2015. why does bcbs have a "monopoly" in nc as they and 1 other company are our only options?
