Yes, when you join a Medicare Prescription Drug Plan that works with the Original Medicare Plan, the plan will mail you a separate card to use when you fill your prescriptions. Your red, white, and blue Medicare card won’t change. You will still use your red, white, and blue Medicare card for hospital and doctor services. If you join a Medicare Advantage Plan or other Medicare Health Plan with prescription drug coverage, you may or may not get a new card depending on the plan.
