A chiropractic loan revolving fund is created in the state treasury as a separate fund under the control of the commission. The commission shall deposit payments made by chiropractic loan recipients and the proceeds from the sale of chiropractic loans, less costs of collection of delinquent chiropractic loans, into the chiropractic loan revolving fund. Moneys credited to the fund shall be used to supplement moneys appropriated for the chiropractic graduate student forgivable loan program, for loan forgiveness to eligible chiropractic physicians, and to pay for loan or interest repayment defaults by eligible chiropractic physicians. Notwithstanding section 8.33, any balance in the fund on June 30 of any fiscal year shall not revert to the general fund of the state.
