Does my Medicare plan renew automatically?

Usually, your current Medicare Advantage or Part D plan will automatically renew if it continues to operate in your area and you do not make a change. However, premiums, benefits, provider networks, drug formularies, and copayments may change each year. Review your Annual Notice of Change before deciding to keep your plan. Your Medicare Supplement plan will automatically renew if you do nothing to change it.
