The Hospital Alliance of Tennessee (HAT) was formed in 1982 to represent the interests of not-for-profit, governmental and public hospitals in the State Legislature, governmental agencies and the executive branch. HAT now represents 65 not-for-profit hospitals throughout Tennessee. HAT develops strategies and positions for a membership that shares common interests and objectives. Acting as a united voice for not-for-profit hospitals, HAT takes an aggressive role in representing its members' interests on issues like TennCare reform, certificate of need revisions and threats to tax-exempt status.
HAT's members are not-for-profit community hospitals that are both private and government health care facilities ranging from small rural hospitals to major teaching and research facilities. Membership is open to Tennessee hospitals that are organized as a 501C (3) or are government-owned.
