You don't need to cancel your old Medicare drug plan. Your old Medicare drug plan coverage will end when your new drug plan begins.
If you want to join a plan or switch plans, do so as soon as possible so that:
- You’ll have your membership card when your coverage begins.
- You can get your prescriptions filled without delay.
You should get a letter from your new Medicare drug plan telling you when your coverage begins.
Don't give personal information to plans that call you unless you're already a member of the plan.
