Planning
October 1: when next year's Medicare plans can be advertised — and the rules that come with it
The volume of Medicare mail and advertising jumps on a specific date, and the date is in the regulations.
If your mailbox and television get noticeably more Medicare-focused in early October, that isn't your imagination and it isn't random. It's a regulatory date.
42 CFR 422.2263(a) says it directly: Medicare Advantage organizations may begin marketing prospective plan year offerings on October 1 of each year for the following contract year. They may market the current and prospective year at the same time, provided materials clearly indicate which year is being discussed.
So the fall has three dates, not one. September is when your own plan tells you what's changing — the Annual Notice of Change, which we covered in the September envelope. October 1 is when everyone else may start describing next year's plans. And October 15 to December 7 is the window when you can actually change anything, with the plan needing your request by December 7 for a January 1 start.
Which means the two-week stretch from October 1 is, by design, information without a decision attached. Nothing can be submitted yet. That's a feature.
What the rules don't allow
Medicare publishes its marketing rules for health plans as a consumer-facing list. It's short, specific, and worth knowing because it converts a vague unease into a clear yes-or-no.
People representing Medicare plans aren't allowed to:
- Come to your home uninvited to sell or endorse anything.
- Call you unless you're already a member of the plan or you've given permission to be contacted. (If you're a member, the agent who helped you join can call.)
- Ask for personal information like bank account or credit card numbers over the phone unless it's needed to process an enrollment request — Medicare notes plans don't need your personal information to give a quote.
- Ask you for payment over the phone or online; the plan must send a bill.
- Offer cash, or gifts worth more than $15, to join — or give you free meals during a sales pitch.
- Require you to speak to a sales agent just to get information about the plan.
- Market plans or enroll you at an educational event like a health fair.
- Talk to you about their plan where you get health care — an exam room, a hospital patient room, a pharmacy counter.
- Sell you a non-health product, like an annuity or life insurance policy, during a Medicare sales pitch.
- Advertise without using specific plan names, or use confusing wording, confusing images, or misleading Medicare logos.
- Tell you they're Medicare supplement (Medigap) policies when they aren't.
And in an appointment
Medicare's list continues into what happens if you do sit down with an agent. During a meeting, they can give you plan materials, explain options, and provide and collect an enrollment form. They cannot charge you a fee to process your enrollment, steer you into a particular plan, describe a plan with claims like “the best” or “highest ranked,” or bring up plan options you didn't agree to discuss unless you ask — that requires a separate appointment form.
Two more from Medicare's list are worth carrying with you. They can't pressure you with lines like “you have to join this plan or you won't have coverage next year.” And they can't ask for names and phone numbers of your friends or family in order to sell to them.
Medicare also notes that independent agents and brokers must be licensed by the state, and the plan must tell the state which agents are selling its plans.
What to do with a rule you think was broken
Medicare's own instruction is plain: if you believe you made the wrong plan choice because of inaccurate or misleading information, call 1-800-MEDICARE and explain the situation. Medicare says call center representatives can help throughout the year with options for making changes.
A calmer way to hold October
Most of what arrives is ordinary and legitimate — plans are permitted to advertise, and October 1 is when they may. The list above isn't a reason to treat every envelope as suspect. It's a short standard to measure against, so that an uninvited knock, an unexpected call, or a request for a bank account number registers immediately as out of bounds rather than merely uncomfortable.
The part that actually deserves your attention this month is quieter and already in your mail: your own plan's notice of what changes January 1. If you'd like the full sequence of dates, it's in the fall coverage calendar, and the short list of what to have ready is in four things to write down.
And when you do want to talk it through with someone who has to follow every rule above, that's a free, no-pressure conversation with a licensed agent — on your invitation, at your pace, including the conversation that ends with nothing to change.
