        (2) a late stage, persistent, or chronic infection or
complications related to such an infection;
        (3) an infection with other strains of borrelia or a

An experimental drug shall be covered as a long-term antibiotic therapy if it is approved for an indication by the United States Food and Drug Administration. A drug, including an experimental drug, shall be covered for an off-label use in the treatment of a tick-borne disease if the drug has been approved by the United States Food and Drug Administration.
