Rights and responsibilities upon disenrollment

Information about ending your membership

You may end your membership in our Medicare health 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, October 15 to December 7.

You also may end your membership during the Medicare Advantage Open Enrollment Period. Effective January 1, 2019, and moving forward every January 1 through March 31, if you're enrolled in a Medicare Advantage plan, you'll have a one-time opportunity to:

  • Switch to a different Medicare Advantage plan
  • Drop your Medicare Advantage plan and return to Original Medicare, Part A and Part B
  • Sign up for a stand-alone Medicare Part D Prescription Drug Plan (if you return to Original Medicare).

In certain situations, you may also be eligible to leave the plan at other times of the year during a Special Enrollment Period.

Usually, to end your membership in our health plan, you simply enroll in another Medicare Advantage plan or stand-alone Part D Prescription Drug Plan during one of the enrollment periods. However, if you want to switch from our health plan to Original Medicare without a Medicare prescription drug plan or switch back to Original Medicare with or without a Medicare Supplement (Medigap) plan, you must ask to be disenrolled from our health plan.

There are 2 ways you can ask to be disenrolled:

  • You can make a request in writing to us. Contact Member Services if you need more information on how to do this.
    or
  • You can contact Medicare at 1-800-MEDICARE (1-800-633-4227), 24 hours a day, 7 days a week. TTY users should call 1-877-486-2048.

Your membership usually ends on the first day of the month after your request is received.

Your rights and responsibilities upon disenrollment

  • You must continue to use network pharmacies (if you have prescription drug coverage) until you are disenrolled from our health plan.
  • You may only disenroll or switch Medicare Advantage plans or prescription drug plans under certain circumstances.
  • You have the right to make a complaint if we ask you to leave our health plan.

Our rights and responsibilities upon your disenrollment

We will let you know, in writing, the date your coverage ends. We have the right to disenroll you for the following reasons:

  • You are no longer eligible for Medicare Part A and/or B or Medicare prescription drug coverage.
  • We are no longer contracting with Medicare or we leave your service area.
  • You permanently move out of our health plan service area and/or move out of the plan service area for 6 or more consecutive months.
  • You materially misrepresent third-party reimbursement.
  • You fail to pay your supplemental dental plan premium, then you will be disenrolled from the supplemental dental benefit.
  • You provide fraudulent information when you enroll or let someone else use your membership card to get covered services.
  • Disruptive behavior.
