Medicare Open Enrollment 2026: What to Know Before Oct 15

Every year, Medicare beneficiaries get a limited window to review their coverage and make changes. That window — October 15 through December 7 — is Medicare's Annual Enrollment Period (AEP), and it's one of the most important dates on the calendar for anyone on Medicare or approaching eligibility.

If you're turning 65 soon, already enrolled in Medicare, or helping a parent navigate their coverage, here's everything you need to know before the deadline.

What Is Medicare Open Enrollment?

Medicare Open Enrollment (also called the Annual Enrollment Period or AEP) is the time each year when Medicare beneficiaries can:

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

Any changes you make during this period take effect on January 1, 2027.

This is your annual opportunity to make sure your plan still fits your needs — because your health, your medications, and the plans available to you can all change from year to year.

Who Should Review Their Coverage This Year?

The short answer: everyone on Medicare. But these situations make a review especially important:

You're turning 65 soon. If your 65th birthday falls between now and early 2027, you may be entering Medicare for the first time. Open Enrollment is separate from your Initial Enrollment Period, but understanding both is critical.

Your medications changed. Drug formularies (the list of covered medications) change every year. A medication that was covered at a low tier last year may cost significantly more in 2027 — or may not be covered at all.

Your doctors changed. If you're on a Medicare Advantage plan and your primary care doctor or specialist left the network, you may need to switch plans to keep seeing them.

Your plan's premium or benefits changed. Insurers send Annual Notice of Change (ANOC) letters each September. If you received one, read it carefully — your costs or benefits may have changed.

You moved. Medicare Advantage plans are regional. If you moved to a new area, your current plan may not be available, or better options may now be accessible.

You're paying too much out of pocket. If your current plan isn't covering your needs affordably, this is the time to find one that does.

What You Can't Change During Open Enrollment

Open Enrollment does NOT allow you to:

• Enroll in Medicare for the first time (that's your Initial Enrollment Period)
• Change a Medicare Supplement (Medigap) plan without medical underwriting in most states
• Make changes outside the Oct 15 – Dec 7 window (with limited exceptions for Special Enrollment Periods)

If you missed your Initial Enrollment Period or need to change a Medigap plan, you'll need to work with a licensed agent to understand your options.

How to Compare Plans Before the Deadline

The Medicare Plan Finder at Medicare.gov is a useful starting point, but it can be overwhelming. Here's a practical approach:

Step 1: Gather Your Information

Before comparing plans, have these ready:

• Your current Medicare card and plan information
• A list of all your prescription medications (name, dosage, frequency)
• The names of your doctors and specialists
• Your preferred pharmacy

Step 2: Know What Matters Most to You

Different people prioritize different things. Ask yourself:

• Do I want the flexibility to see any doctor (Original Medicare) or am I comfortable with a network (Medicare Advantage)?
• How important are extra benefits like dental, vision, and hearing?
• What's my budget for monthly premiums vs. out-of-pocket costs?
• Do I travel frequently? (Some plans have limited out-of-area coverage)

Step 3: Compare Apples to Apples

When comparing plans, look at:

• Monthly premium — what you pay every month regardless of use
• Annual deductible — what you pay before coverage kicks in
• Copays and coinsurance — your share of costs for doctor visits, hospital stays, and procedures
• Out-of-pocket maximum — the most you'll pay in a year (Medicare Advantage plans have a cap; Original Medicare does not)
• Drug formulary — whether your medications are covered and at what tier
• Network — whether your doctors are in-network

Step 4: Get Expert Help

Comparing Medicare plans is genuinely complex. A licensed Medicare insurance agent can do the comparison work for you — at no cost to you. Agents are compensated by the insurance carriers, so their guidance is free.

Don't wait until December to start reviewing your options. The best plans fill up, and getting expert guidance takes time.

What to Expect From a Free Medicare Review

A free Medicare review with a licensed agent typically covers:

• Your current coverage — what you have and whether it's still the best fit
• Plan comparison — side-by-side look at your options for 2027
• Drug coverage check — making sure your medications are covered affordably
• Cost analysis — estimating your total annual costs under different plans
• Enrollment assistance — help completing your enrollment if you decide to switch

The whole process usually takes 30–60 minutes and can save you hundreds or even thousands of dollars in annual costs.

Don't Miss the December 7 Deadline

Once Open Enrollment closes on December 7, you're locked into your plan for all of 2027 — unless you qualify for a Special Enrollment Period due to a qualifying life event.

The best time to review your coverage is now, before the rush of October and November when agents are at their busiest.
