A person making payment to the patient or to his or her attorneys or heirs or legal representatives as compensation for the injury sustained, after the filing and mailing of the notice without paying to the hospital the amount of its lien or so much thereof as can be satisfied out of the monies due after any final judgment or compromise or settlement agreement after paying the amount of any prior liens, shall, for one year from the date of payment, be liable to the hospital for the amount which the hospital was entitled to receive; and the hospital may, within that year, enforce its lien by a civil action against the person making any such payment. Provided, however, that unless said action is brought within said year, such lien shall be void. (Added 1963, No. 209, § 3, eff. Oct. 1, 1963.)
