BlueCross of Tennessee said it will offer Obamacare plans in Knoxville next year after the city was going to be without any Obamacare insurer.

The insurer’s decision comes as the stability of the individual market is being thrown into doubt after insurers in three states said they want to raise prices by double digits next year. The health of Obamacare is also taking center stage in Congress’ battle to repeal it, which has moved to the Senate.
