Verification Letter

You will receive a letter from us within 10 days of your enrollment. The letter will contain several questions to verify your enrollment and if you understand your plan choice.

About two weeks after you get your ID card, you'll receive your Welcome Kit. It includes your Evidence of Coverage. And it tells you what you need to know about being a member of Blue Cross Medicare Advantage.

Your Protections in this Plan

Blue Cross Medicare Advantage agrees to stay in the program for a full year at a time. Each year, the plan decides whether to carry on for another year. Even if Blue Cross Medicare Advantage leaves the program, you will not lose Medicare coverage.

Guidelines for Disenrollment

Disenrollment from Blue Cross Medicare Advantage means ending your membership. Disenrollment can be voluntary or involuntary. We are not allowed to ask you to leave the plan because of your health.

Voluntary Disenrollment

You may end your membership in our plan only during certain times of the year, known as enrollment periods. All members have the opportunity to leave the plan during the Annual Enrollment Period. In certain situations, you may also be eligible to leave the plan at other times of the year. Refer to your Evidence of Coverage for more information.

To voluntarily disenroll:

  • You must choose to leave the plan.
  • You must provide a signed written notice to Blue Cross Medicare Advantage (or, if enrolled through your employer group, the employer group must provide Blue Cross Medicare Advantage with the request to disenroll you).
  • Call 1-800-MEDICARE (1-800-633-4227) 24 hours a day, 7 days a week. If you are hearing or speech impaired, please call 1-877-486-2048.
