Sec. 13. (a) The governing board shall establish reasonable charges for patient care and other hospital services for the residents of the county and may provide patient care and other hospital services to nonresidents of the county upon terms and conditions the board establishes by rule.
(b) The governing board may give appropriate discounts of charges to patients.
(c) In establishing charges, the governing board may include a reasonable charge for depreciation and obsolescence of property, plant, and equipment.
(d) The board may periodically transfer all or part of the charges for depreciation and obsolescence to a fund to be used by and at the discretion of the board only for the purpose of building, remodeling, repairing, replacing, or making additions to the hospital building or buildings. However, in any year in which there is a tax levy for the general operation and maintenance of the hospital, the board shall not make a transfer to the fund. In an emergency, the board may borrow from the fund for the operating fund of the hospital and shall reimburse the fund within two (2) years.
(e) The authority granted to establish the fund does not limit the power and authority of the board, the county executive, the county fiscal body, or other units of government to finance hospital buildings by other methods.
