Maryland Commercial Law Section 16-601

      (a)      A hospital which furnishes medical or other services to a patient injured in an accident not covered by the Maryland Workers' Compensation Act has a lien on 50 percent of the recovery or sum which the patient or, in case of death, the heirs or personal representative of the patient collect in judgment, settlement, or compromise of the patient's claim against another for damages on account of the injuries.

      (b)      (1)      The lien secures the reasonable and necessary charges of the hospital for treatment, care, and maintenance provided to the patient.

            (2)      However, the charges secured may not exceed those allowed by the State Workers' Compensation Commission for medical services rendered to individuals coming under the Maryland Workers' Compensation Act.

      (c)      A hospital's lien is subordinate only to an attorney's lien for professional services for collecting or obtaining damages.
