2027 Medicare Annual Enrollment: What You Need to Know Before October 15

Every fall, Medicare gives you a chance to step back, look at your coverage, and make sure it still fits your life. That window is called the Annual Enrollment Period—and it's one of the most important times of the year for anyone on Medicare.

Let's walk through what to expect this year, what's changing, and how to feel confident about your choices for 2027.

What Is Medicare Annual Enrollment?

The Medicare Annual Enrollment Period (AEP) is the one time each year when most people with Medicare can make changes to their coverage for the coming year.

Here are the key dates to remember:

• AEP runs from October 15 through December 7, 2026.
• Any changes you make become effective January 1, 2027.

During this window, you can:

• Switch from Original Medicare to a Medicare Advantage plan
• Switch from a Medicare Advantage plan back to Original Medicare
• Change from one Medicare Advantage plan to another
• Join, switch, or drop a Medicare Part D prescription drug plan

If you're happy with your current coverage and don't want to make any changes, you generally don't have to do anything. Your plan will simply renew for the new year—but that's exactly why it's so important to review the details, which I'll explain in a moment.

Why I Recommend Reviewing Your Plan Every Year

Every year I meet with clients who assume their Medicare plan hasn't changed—only to discover their doctors, prescriptions, or costs are different for the upcoming year.

Your plan may keep the same name, but what it actually covers can change from year to year.

Insurance companies update their plans annually. That means the doctors in your network, the medications on your formulary, your copays, and even your monthly premium can shift—even if nothing about your health has changed.

When you review your plan each fall, you give yourself the chance to catch those changes before they catch you by surprise. A few minutes of review now can save you from an unexpected bill or a coverage gap next year.

What's New for Medicare in 2027?

Each year, CMS (the Centers for Medicare & Medicaid Services) updates Medicare rules and plan structures. Here's a simple summary of what's on the horizon for 2027:

• Medicare Advantage updates: CMS continues to refine Medicare Advantage plan rules, including how plans are paid and what benefits they can offer. Some plans may adjust their extra benefits, networks, or costs.
• Medicare Part D redesign continues: The redesign of Medicare Part D that began under the Inflation Reduction Act continues, including the cap on out-of-pocket drug costs.
• End of the Part D Premium Stabilization Demonstration: The temporary demonstration program that helped stabilize Part D premiums will conclude after the 2026 plan year. This means some stand-alone drug plans may adjust their premiums for 2027.
• Carrier benefit changes: Insurance companies review and update their benefits each year, so your plan's copays, network, and formulary may change.

All of this is why your Annual Notice of Change (ANOC) letter matters so much.

Watch for Your Annual Notice of Change (ANOC)

Your ANOC is a letter from your current Medicare plan that explains exactly what's changing for the upcoming year. Here's what to know:

• What it is: A clear summary of any changes to your plan's costs, benefits, and coverage for the new year.
• When it arrives: Plans are required to send your ANOC by September 30 each year.
• Why it matters: It's your personal heads-up. If your doctor is leaving the network, a medication is changing tiers, or your premium is going up, the ANOC is where you'll find out.

I always tell my clients: don't set that letter aside. Open it, read it, and bring it to your Medicare review. It's the single best way to know whether your current plan is still the right fit.

What to Bring to Your Medicare Review

To make the most of our time together, here's a simple checklist of what to have ready:

• Your Medicare card
• Your current plan ID card
• A list of your prescription medications (including dosages)
• Names of your preferred doctors and specialists
• The name and location of your preferred pharmacy
• Your ANOC letter
• Any questions you'd like answered

You don't need to have everything perfectly organized—just gather what you can. If you're missing something, that's okay. We'll work through it together.

Why Schedule Early?

Appointments for Annual Enrollment begin filling before October 15.

When you schedule early, you give yourself the gift of time—time to compare plans carefully, ask questions, and make a decision without feeling rushed before the December 7 deadline.

Waiting until the last week of AEP often means fewer appointment times, less time to compare your options, and more stress. I'd much rather help you make a calm, confident decision than a rushed one.
