A federal judge is hearing arguments in a class-action lawsuit that claims delays in processing TennCare applications have left thousands of low-income Tennesseans without timely access to medical care.

TennCare applicants testified in court in Nashville on Tuesday in a lawsuit that was originally filed in 2014 after the rollout of the Affordable Care Act. At the time, the state's computer system was unable to handle a new method of determining TennCare eligibility.

Attorneys for the state say the problem is fixed and now less than 1 percent of applications are not resolved within the 45 or 90 days required by law, depending on the type of application.
