Medicare Open Enrollment 2027: What Changed

What's Different About Medicare Open Enrollment in 2027

Several key details have changed for Medicare Open Enrollment in 2027. Prescription drug pricing rules have shifted again, several Medicare Advantage plans are pulling out of certain counties, and the annual cost figures have moved just enough to catch people off guard.

Comparing plans already felt like a lot. Add new drug pricing structures and shrinking plan networks, and it is easy to feel stuck before you even start.

This guide walks through what actually changed for 2027, how to compare your options without getting lost in fine print, and how to enroll with a decision you feel good about, not just one you rushed through.

If you are turning 65 this year, this process looks a little different for you. Rather than comparing changes to a plan you already have, you are starting from scratch with dozens of Medicare Advantage plans, Medigap options, and Part D drug plans all competing for attention at once. It is common to feel overwhelmed trying to figure out where to even begin. The good news is that the same fundamentals in this guide, checking your doctors, checking your prescriptions, and comparing total costs rather than just premiums, apply just as much to a first-time decision as they do to someone reevaluating a long-held plan.

Medicare Terms and Plan Types, Explained in Plain Language

Original Medicare is coverage run directly through the federal government, split into Part A for hospital stays and Part B for doctor visits and outpatient care. Medicare Advantage, sometimes called Part C, is an alternative where private insurers manage your benefits, often bundling in drug coverage and extras like dental or vision. Part D is stand-alone prescription drug coverage you can pair with Original Medicare.

Knowing these terms matters more this year because several plans have changed their formularies, networks, and ratings all at once. Comparing apples to apples gets much easier once you know what each word actually means.

How Medicare Advantage and Original Medicare Differ in 2027

The biggest structural difference remains provider choice. Original Medicare lets you see nearly any doctor who accepts Medicare nationwide, while Medicare Advantage generally limits you to an in-network list, though some plans allow out-of-network care at higher cost.

What has not changed is the core split between the two paths: you still choose one primary structure and build coverage around it. The 2027 Medicare Advantage maximum out-of-pocket limit is capped at $9,250, according to CMS.gov, a detail worth knowing before you assume Original Medicare with a supplement is automatically the pricier route.

If you choose Original Medicare, many people also look at a Medigap, or Medicare Supplement, plan to help cover the gaps Part A and Part B leave behind, such as coinsurance and deductibles. Medigap plans are sold by private insurers, are standardized by letter (like Plan G or Plan N), and are designed to pair with Original Medicare plus a separate Part D drug plan rather than with Medicare Advantage. Unlike Medicare Advantage, Medigap generally does not use provider networks, so you can see any doctor who accepts Medicare. Premiums for Medigap are separate from your Part B premium and vary by insurer, location, and the specific plan letter you choose.

Why Plan Non-Renewals Are a Bigger Concern This Year

A noticeable number of Medicare Advantage plans are exiting counties or discontinuing entirely for 2027. If your plan is one of them, you will typically receive a non-renewal notice by early fall, giving you time to choose something new before your coverage ends.

It is a real worry to lose a plan you have relied on for years, especially if it covered your doctors well. The good news is you are guaranteed a chance to enroll in new coverage, so you will not be left without options.

Start by checking your Annual Notice of Change letter, calling your plan directly, or reviewing your plan status through <a href="https://www.medicare.gov/plan-compare">Medicare's plan comparison tool</a>. Confirming early gives you more time to compare replacement options calmly instead of scrambling in December.</p>

New Drug Pricing Structures and What They Mean for Your Wallet

Part D costs have shifted again for 2027. According to CMS.gov, the maximum deductible rises to $615, up from $590 in 2025, and according to KFF, the average premium sits around $34.50 a month, though your actual premium depends on the plan you choose.

That cap has changed how people budget for medications, but it does not mean every plan handles the phases before the cap the same way. Two plans can both include the same cap and still leave you with very different costs depending on tiered copays and deductible timing.

This is why reviewing your Part D or Medicare Advantage drug coverage every year still matters, even if last year's plan treated you well. Formularies change annually, and a medication that was covered in a low tier last year could move to a higher, costlier tier this year.</p>

💡 Eddie's Pro Tip

I always tell people not to assume their current plan carries the same drug costs into the new year. I've seen clients keep a plan out of loyalty, only to discover their maintenance medication jumped a tier and their monthly cost tripled. A ten-minute formulary check each fall can save you from that surprise.

Making Sure Your Doctors and Prescriptions Are Actually Covered

Before you enroll in or renew any plan, confirm your preferred doctors are still in-network for 2027. Networks shift year to year, and a specialist you have seen for a decade could quietly drop off a plan's list without much fanfare.

1. Call your doctor's office directly and ask which 2027 plans they accept

2. Use the plan's online provider directory, but verify by phone since directories can be outdated

3. Check your medications against the plan's formulary document, not just a summary flyer

4. Ask about tier placement and whether prior authorization is required for any prescription

Assuming last year's coverage automatically carries over is one of the most common and avoidable mistakes during open enrollment. Even if you are staying with the same plan, formularies and networks are reevaluated annually, so a quick review protects you from surprises after you have already committed.</p>

Your 2027 Open Enrollment Checklist: Avoiding Deadlines and Costly Mistakes

According to Medicare.gov, the Medicare Open Enrollment Period runs from October 15 through December 7, with changes taking effect January 1, 2027. Miss this window, and you may be locked into your current plan for another year unless you qualify for a Special Enrollment Period. This is separate from the Medicare Advantage Open Enrollment Period, which runs January 1 through March 31 and allows those already enrolled in a Medicare Advantage plan to switch to a different Medicare Advantage plan or return to Original Medicare, but it does not allow switching from Original Medicare into Medicare Advantage.</p>

• Review your Annual Notice of Change letter for cost and coverage updates

• Confirm your doctors and pharmacies are in-network for 2027

• Check your medications against each plan's updated formulary

• Compare total annual costs, not just the monthly premium

• Note the December 7 deadline and set a reminder well before it

Comparing Total Costs, Not Just the Monthly Premium

A plan with a low premium can still cost more overall once you add up deductibles, copays, and coinsurance. According to CMS.gov, here are the 2026 deductible figures that affect your true costs depending on how much care you use:</p>

• Part B deductible: $283 per year

• Part A deductible: $1,736 per benefit period

To estimate your real annual cost, add your expected premiums to likely copays based on how often you see doctors or fill prescriptions. This gives a far more honest picture than premium price alone.</p>
