• We value your privacy, so it’s important to know you can prevent Medicare from sharing this information at any time. Simply call 1-800 MEDICARE (1-800-633-4227). TTY users should call 1-877-486-2048. Tell the operator you’re calling about ACOs and you don’t want to share your health care information with an ACO.

    After your talk with someone at 1-800 MEDICARE, Medicare will update its records to show that you don’t want to share your health care information. If you call 1-800 Medicare, you’ll get a letter confirming this change. It’ll take about 45 days for this change to take effect.
