Notwithstanding any other provision of law, the department may, in addition to the advance payment under Section 124410, provide for prospective payments for services to be performed under any agreement entered into pursuant to the Primary Care Services Act (Section 27). These prospective payments may be provided each month to a contracting agency on one of the following bases:
(a) One-twelfth of the total funding award each month.
(b) One-twelfth of 75 percent of the funding award, if a 25 percent advance payment is also provided.
Prospective payments may be made to those nonprofit or public agencies that request prospective payments and may be adjusted if necessary during the project period after the submission and review of required program reports.
