Local Government, General - As enacted, requires TACIR to study the economic impact on local jurisdictions that are required to provide ambulance services and emergency and non-emergency transport reimbursement; requires TACIR to submit a report of the findings and recommendations. - Amends TCA Title 7, Chapter 61.

HB 83 requires cities that do not provide their own ambulance services to reimburse counties for ambulance services provided within their boundaries. The reimbursement amount is capped at 50% of the total cost and calculated based on the city's population relative to the county's population using the latest federal census data. The bill also mandates the Tennessee Advisory Commission on Intergovernmental Relations (TACIR) to study the financial impact of this requirement on local governments and submit a report with findings and recommendations. This affects cities and counties that share ambulance service responsibilities, directly changing how costs are shared between municipal and county governments.
