Determination of uniform Statewide uncompensated care add-on

5. a. For the periods beginning January or July of the hospitals' rate year, the department shall determine a uniform Statewide uncompensated care add-on. The commission shall approve the add-on before it is included in hospital rates. The add-on shall be determined by dividing the Statewide amount of approved uncompensated care plus an amount adequate to fund the reasonable cost of administering the fund pursuant to subsection a. of section 4 of P.L.1991, c.187 (C.26:2H-18.27) and to maintain the reserve pursuant to subsection c. of section 4 of P.L.1991, c.187 (C.26:2H-18.27), by the Statewide amount of approved revenue for all payers and approved revenue for medically indigent persons less the Statewide amount of approved uncompensated care. The Medicaid program shall provide its share of the uncompensated care add-on, as determined by the commission, through a direct contribution to the fund of an amount equal to the Medicaid program's State share of the uncompensated care add-on. The add-on and any increases made to the add-on are an allowable cost and shall be included as part of the hospital's rates as established by the commission. b. The amount of money raised by the uniform Statewide uncompensated care add-on, as a percentage of all governmental and nongovernmental approved revenue, shall not exceed 13%, except that the add-on shall not exceed 19.1%. The commissioner shall establish the following target levels for the add-on: 16% by July 1, 1993, 13% by July 1, 1994 and 10% by July 1, 1995. c. The uniform Statewide uncompensated care add-on for patients whose hospital bills are paid by a health maintenance organization or other payer which has negotiated a discounted rate of payment with the hospital shall be based on the full rate of reimbursement for the services provided by the hospital to the patient under the hospital reimbursement system established pursuant to P.L.1978, c.83, rather than on the discounted rate of payment. d. No provision of this section shall be construed to preclude the commission from approving individual hospital rate increases for uncompensated care in addition to the add-on. Such increases, however, shall not be paid from the moneys in the Health Care Trust Fund.
