CA Health & Safety Code Section 127445

Notwithstanding any other provision of law, the amounts paid by parties for services resulting from reduced or waived charges under a hospital’s discounted payment or charity care policy shall not constitute a hospital’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 a hospital’s median non-Medicare or 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.
