How Can I Cancel Medicare Part B? 
You can call 1-800-MEDICARE . I highly discourage it however unless you have an employer group plan . You can be penalized by Medicare for every month that you do not carry Part B that you are eligible . If you are in a Medicare Advantage Plan you will be disenrolled because you must have part B to be enrolled in a Medicare Advantage . Not a good idea to cancel your part B . The potential cost over what you would save could be tremendous .
