CMS Issues New Medicare Cards April 2018 to April 2019
Upon receipt of the New Medicare card, destroy the old one, and start using the new one immediately.
Only share your Medicare card with doctors, hospitals, outpatient centers, pharmacies, insurers or people assisting with matters pertaining to Medicare, on behalf of the beneficiary.
Keep your Medicare Advantage Plan Card! If you participate in a Medicare Advantage Plan, your Medicare Advantage Plan ID card is the primary card to use for payment of medical services. However, carry your new Medicare card in case you are asked to show it.
