SB 748 changes how Tennessee's TennCare program reimburses ambulance services. It requires TennCare to pay public or private ambulance providers in Tennessee at least 67.5% of Medicare's rate for emergency transports and 100% of Medicare's rate for non-emergency transports. This applies specifically to ambulance services with a base of operations in Tennessee that bill for covered services provided to TennCare recipients. The bill amends Tennessee law to establish these specific reimbursement rates relative to Medicare's allowable charges.
