If your card is lost or stolen while you're abroad you should contact the Territorial Health Insurance Fund and apply for a Provisional Replacement Certificate (PRC). Members of your family can do this on your behalf if necessary. The PRC will provide you with the same cover as an European Health Insurance Card (EHIC) until you return home.
If leave Lithuania without your EHIC and treatment becomes medically necessary during your visit, you may be issued with a PRC as well. At your request the PRC will be sent directly to the place of treatment.
