You should have received a new Wellmark ID card in the mail. Your new ID card includes a new Wellmark ID number, so it’s important to put it in your wallet and destroy any old ID cards. If you use an old card, your claims could be delayed or possibly denied. Always show your doctor’s office or pharmacy the most up-to-date card. To ensure you are using the most recent card, look for the print date shown in the lower left corner on the front of your card. You may log into your MyWellmark account to request additional cards if needed.
