Adults getting TennCare may soon be required to work under a bill passed by the state Senate. It would mandate that able-bodied adults work, volunteer or go to school at least 20 hours a week. Parents with children under six years old, and those who are sick, or caring for someone who is sick, would be exempt from the mandate. Senator Kerry Roberts (R-Springfield), who sponsored the bill, estimates the work requirement will affect up to 100,000 people. He says similar work requirements are already in effect for the food stamp and SNAP programs. The proposed change in state law must be submitted to the Federal Centers for Medicare and Medicaid Services for approval.
