Section 7. Each acute hospital, ambulatory surgical center and surcharge payor shall pay to the commonwealth an amount for the estimated expenses of the center and for the other purposes described in this chapter which shall include any transfer made to the Community Hospital Reinvestment Trust Fund established in section 2TTTT of chapter 29.

The assessed amount for hospitals and ambulatory surgical centers shall be not less than 33 per cent of the amount appropriated by the general court for the expenses of the center and for the other purposes described in this chapter which shall include any transfer made to the Community Hospital Reinvestment Trust Fund established in section 2TTTT of chapter 29 minus amounts collected from (1) filing fees; (2) fees and charges generated by the center's publication or dissemination of reports and information; and (3) federal matching revenues received for these expenses or received retroactively for expenses of predecessor agencies. Each acute hospital and ambulatory surgical center shall pay the assessed amount multiplied by the ratio of the hospital's or ambulatory surgical center's gross patient service revenues to the total of all such hospital's and ambulatory surgical center's gross patient services revenues. Each acute hospital and ambulatory surgical center shall make a preliminary payment to the center on October 1 of each year in an amount equal to 1/2 of the previous year's total assessment. Thereafter, each hospital and ambulatory surgical center shall pay, within 30 days notice from the center, the balance of the total assessment for the current year based upon its most current projected gross patient service revenue. The center shall subsequently adjust the assessment for any variation in actual and estimated expenses of the center and for changes in hospital or ambulatory surgical center gross patient service revenue. The estimated and actual expenses shall include an amount equal to the cost of fringe benefits and indirect expenses, as established by the comptroller under section 5D of chapter 29. In the event of late payment by any such hospital or ambulatory surgical center, the treasurer shall advance the amount of due and unpaid funds to the center before the receipt of the monies in anticipation of the revenues up to the amount authorized in the then current budget attributable to the assessments and the center shall reimburse the treasurer for the advances upon receipt of the revenues. This section shall not apply to any state institution or to any acute hospital which is operated by a city or town.

The assessed amount for surcharge payors shall be not less than 33 per cent of the amount appropriated by the general court for the expenses of the center and for the other purposes described in this chapter which shall include any transfer made to the Community Hospital Reinvestment Trust Fund established in section 2TTTT of chapter 29 minus amounts collected from (1) filing fees; (2) fees and charges generated by the center's publication or dissemination of reports and information; and (3) federal matching revenues received for these expenses or received retroactively for expenses of predecessor agencies. The assessment on surcharge payors shall be calculated and collected in the same manner as the assessment authorized under section 68 of chapter 118E.
