En español | When you first sign up for Medicare, the Social Security Administration (which handles Medicare enrollment) automatically enrolls you in the original Medicare program. If you prefer to be in a private Medicare Advantage managed care plan (such as an HMO or PPO) you can join one during these time frames:
You can enroll in a Medicare Advantage plan in your area by using the online plan-finder program on Medicare’s website, at https://www.medicare.gov/find-a-plan/questions/home.aspx. Or you can call Medicare at 800-633-4227 (TTY: 877-486-2048) for contact information.
