Recently, we have been receiving malicious nuisance calls from people claiming to be staff members of our hospital, claiming to be contacting you to confirm that your health insurance card has expired, and asking for personal information or requesting that you submit your health insurance card. If we have any inquiries about your health insurance card, we will always call from the hospital's main number (0463-93-1121). Please check the number you are receiving calls from, and be careful not to answer inquiries you are not familiar with.
