(a) The department of health is authorized to develop and implement a prescription drug discount plan, which shall be known as “Volunteer Rx,” or, if the department of health deems appropriate, may contract for, pursuant to state purchasing laws, a prescription drug discount plan. The purpose of this section is to assist in providing, when possible, cost savings on medications for uninsured Tennesseans, or for insured Tennesseans whose insurance does not provide for prescription drug coverage on or after January 1, 2005.

(b) Notwithstanding subsection (a), the department of health may, if funding is made available through the general appropriations act, provide benefits through the prescription drug discount plan. The benefits would be limited by the funds specifically appropriated for that purpose. The department of health shall also have the authority to develop and implement prescription drug discount plans targeted for specific defined populations. The plans may also incorporate benefits; provided, that funds are specifically allocated for the benefits in the general appropriations act.

(c) In developing the plans authorized by this section, the department of health may consider the use of different means to lower the overall cost to participants, including, but not limited to, the payment or waiver of any membership fees, as well as the use of cost-sharing arrangements and deductibles.

(d) Nothing in the creation of a prescription drug discount program, pursuant to this section, shall be construed as creating any entitlement by any individuals or entities to any services or medications.
