Okla. Stat. tit. 42, § 43
Every hospital in the State of Oklahoma, which shall furnish emergency medical or other service to any patient injured by reason of an accident not covered by the Workers' Compensation Act, shall, if such injured party shall assert or maintain a claim against another for damages on account of such injuries, have a lien upon that part going or belonging to such patient of any recovery or sum had or collected or to be collected by such patient, or by his heirs, personal representatives or next of kin in the case of his death, whether by judgment or by settlement or compromise to the amount of the reasonable and necessary charges of such hospital for the treatment, care and maintenance of such patient in such hospital up to the date of payment of such damages: Provided, however, that this lien shall be inferior to any lien or claim of any attorney or attorneys for handling the claim on behalf of such patient, his heirs or personal representatives; provided further, that the lien herein set forth shall not be applied or considered valid against any claim for amounts due under the Workers' Compensation Act in this state.
