(f) The remedy provided in this section is cumulative with any other remedy available by law.
(g) The Legislature hereby finds and declares that facilities described in subdivision (b) have an existing duty to refrain from committing spoliation of evidence in actions brought pursuant to Section 15657 and, therefore, this section does not impose a new requirement on those facilities that is reimbursable pursuant to Article 3.8 (commencing with Section 14126), any other law or regulation governing Medi-Cal ratesetting, or the California Medicaid State Plan.
(h) If there is a final judicial determination in any action by any party, or a final determination by the Centers for Medicare and Medicaid Services, that the state is required by state or federal law or regulation to provide reimbursement under the Medi-Cal program to the health care facilities described in subdivision (b) for costs associated with this section, and the Legislature does not appropriate sufficient funds to pay for those costs, this section shall become inoperative.
