Notwithstanding any other provision of law, the amounts paid by parties for services resulting from reduced or waived charges under an emergency physician's discounted payment policy shall not constitute an emergency physician's uniform, published, prevailing, or customary charges, its usual fees to the general public, or its charges to non-Medi-Cal purchasers under comparable circumstances, and shall not be used to calculate an emergency physician's median non-Medicare or non-Medi-Cal charges, for purposes of any payment limit under the federal Medicare Program, the Medi-Cal program, or any other federal or state-financed health care program.
