Disenrollment Rights & Responsibilities

When your enrollment in a Medicare Advantage plan ends, it’s called disenrollment.

When YOU choose to end your coverage, it’s called voluntary disenrollment. You are allowed to voluntarily disenroll only during certain times of the year, such as the annual election period.

When your coverage ends for another reason, it’s called involuntary disenrollment. Why would your coverage end involuntarily? If you leave your plan’s service area for more than six months for HMO plans or fail to pay your plan premium, you may be disenrolled involuntarily.

You will be notified if you are being disenrolled from a plan—whether it is a voluntary or involuntary disenrollment. The reason for disenrollment and the date your coverage ends will be included in the notification.

If you’d like to voluntarily disenroll from your plan or have questions about disenrollment, contact Medicare or Blue Cross Blue Shield of Arizona (AZ Blue):

Your rights and responsibilities when disenrolling

Federal law requires the following protections, but your state may have laws that provide additional Medigap protections. If you will be changing to Original Medicare, you may have a special temporary right to buy a Medigap policy, also known as Medicare Supplement insurance, even if you have health problems.

For example, if you are age 65 or older and you enrolled in Medicare Part B within the past six months, or if you move out of the service area, you may have this special right. If you have questions about Medigap or Medigap rights in Arizona, contact the Arizona State Health Insurance Program.

We cannot ask you to leave your health plan for health-related reasons

If you feel that you are being encouraged or asked to leave your Plan because of your health, call the national Medicare help line at 1-800-MEDICARE (1-800-633-4227), TTY: 1-877-486-2048. Assistance is available 24 hours a day, 7 days a week.

If we end your membership involuntarily, we will send you notification telling you the reason and what to do if you disagree with our decision.

You have the right to file a complaint with Medicare if we end your membership in our Plan. Please contact them at the information above or Medicare.gov.
