To the extent that payment for covered expenses has been made under medical assistance for health care items or services furnished to an individual, in any case where a third party has a legal liability to make payments, the state is considered to have acquired the rights of the individual to payment by any other party for those health care items or services. Recovery pursuant to the subrogation rights, assignment, or enforcement of the lien granted to the authority by this section shall not be reduced, prorated, or applied to only a portion of a judgment, award, or settlement, except as provided in RCW
41.05A.060 and
41.05A.070. The doctrine of equitable subrogation shall not apply to defeat, reduce, or prorate recovery by the authority as to its assignment, lien, or subrogation rights.
