Tennessee’s subsidized health care plan for adults is expanding benefits and keeping premiums at the current levels. The CoverTN program targets the uninsured who aren’t eligible for Medicaid. Under the plan, the state kicks in one-third of the monthly premium, while employers have the option of paying for another third. Each third averages about $60 per month. Current benefits include up to 12 primary care and six specialist visits per year. The additional benefits announced Tuesday include adding one more outpatient surgical and non-surgical visit each year. The plan will now also fully cover annual mammogram screening and remove pharmacy limits on flu medicines. The state last week announced it is capping enrollment in its CoverKids program because of budget constraints.
