Major Medicare Changes in 2027: What You Need to Know

Why Does Medicare Change Each Year?

CMS updates the rules annually because the program keeps moving. New laws take effect, plan behavior shifts, and the Centers for Medicare and Medicaid Services adjusts oversight to match.

Plans change on their own schedule too. Premiums, formularies, and provider networks reset each plan year, and a plan that worked last year may not this year.

That is why the annual notice matters. Your current plan mails one every fall listing what is different, and it arrives whether or not the federal rules changed anything.

What Is Changing With Medicare in 2027?

The final rule covers five areas. Most beneficiaries will notice two of them and never hear about the rest.

Individual plans still vary. These medicare changes set the rules that all Medicare Advantage and Part D plans follow, and benefits, premiums, prescription drug formularies, and provider networks will continue to differ by carrier and by county.

Medicare Advantage Star Ratings Are Changing

Star Ratings let you compare Medicare Advantage and Part D plans on quality. Contracts are rated on up to 43 measures across five categories, and plans rated four stars or higher earn bonus payments from Medicare.

Most enrollees are already in highly rated plans. The average Medicare Advantage quality rating is 3.98 stars, and 64% of enrollees are in a plan rated four stars or better.

What CMS Is Removing and Adding

CMS is cutting 11 measures from the star ratings system. Those focused on administrative processes and on areas where nearly every plan scores well, so the ratings did not help you distinguish between plans.

Two other changes matter. CMS is not implementing the Excellent Health Outcomes for All reward and will continue the historical reward factor. It is also adding a Part C depression screening and follow-up measure to address behavioral health gaps.

Read Star Ratings Alongside Everything Else

A high rating is not a recommendation for you. Ratings measure a plan’s performance across all its enrollees, and they say nothing about whether your doctors are in network or your prescriptions are covered.

Weigh them against the things that affect you directly. Provider networks, out-of-pocket costs, covered benefits, and prescription drug coverage all matter more to your experience than a half-star difference.

Part D and the Inflation Reduction Act

The Inflation Reduction Act rewrote Part D, and CMS ran those changes through program instructions rather than regulation. That temporary authority is expiring, so the rule makes them permanent in Medicare regulations for 2027 and beyond.

Four protections are now codified:

• The coverage gap phase is gone. What people called the donut hole no longer exists in the Part D benefit structure.
• A reduced annual out-of-pocket threshold. The cap on what you spend on covered drugs each year stays in place.
• No cost sharing in the catastrophic phase. Once you hit the cap, covered prescriptions cost you nothing for the rest of the year.
• The Manufacturer Discount Program. This replaced the Coverage Gap Discount Program in 2025 and is now permanent.

Nothing here is new to 2027. These protections are already in place, and codifying them means they no longer depend on CMS renewing the instructions each year.

Plan-level details still vary. Formularies, premiums, deductibles, and pharmacy networks differ across Part D plans, and none of that is set by the rule.

Supplemental Benefits, Debit Cards, and the Chronically Ill

Supplemental benefits are the extras Medicare Advantage plans add beyond what Original Medicare covers. The rule tightens how plans administer them and who qualifies for them.

Special Supplemental Benefits for the Chronically Ill go to enrollees with qualifying conditions. Plans set their own eligibility requirements, and the rule now requires them to publicly post those criteria and clarifies what the requirements must include.

New Rules for Benefit Debit Cards

Many plans deliver supplemental benefits through a card. The rule codifies how those work, and two requirements matter to you:

• Debit cards must be electronically linked to covered items. A real-time mechanism verifies at the point of sale that what you are buying is actually a plan-covered benefit.
• Cards are limited to the specific plan year. Balances do not carry forward, so unused funds are lost at year-end.

Check your balance before December. If your plan gives you a benefit card, the money on it expires at the end of the plan year, and no one is required to remind you.

What Plans May Not Cover

CMS also clarified an exclusion. Cannabis products that are illegal under applicable state or federal law are not allowable as supplemental benefits for the chronically ill.

What the Final Rule Removes

Not every change adds something. CMS finalized several removals under Executive Order 14192, describing the requirements it cut as duplicative and burdensome, limiting beneficiary choice, hindering innovation, and increasing costs.

What is going away:

• Mid-year notices about unused supplemental benefits. Plans no longer have to tell you mid-year that you have unused benefits.
• Health disparity requirements in quality improvement programs. MA plans no longer need to include activities to reduce health disparities.
• Health equity requirements for utilization management committees. The health equity expert, the annual analyses, and the public posting requirement are all eliminated.
• Creditable coverage disclosures for account-based plans. HRAs, FSAs, and health savings accounts are now exempt.
• Restrictions on agent and broker conversations. Limits on the time and manner of those conversations are removed.

The first one matters most to you. Under the old requirement, plans had to send a reminder about unused supplemental benefits; without it, nothing prompts you to use what you already paid for.

How Could These Major Changes Affect Your Coverage?

Most of the major Medicare changes in 2027 affect what plans must do, not what you receive. The practical effects land in a few places.

Comparing Medicare Advantage and Part D Plans

Star Ratings will be simpler and less useful on their own. With 11 measures gone, the ratings say less about administrative performance and more about clinical care. 

This means that comparing Medicare Advantage and Part D plans requires looking beyond the stars to provider networks and out-of-pocket costs.

Supplemental benefits deserve a closer read. Debit card rules and eligibility requirements are tighter, and with the mid-year notice gone, tracking what you have and what expires falls to you.

What Stays the Same

Your Part D protections are unchanged and now permanent. The out-of-pocket cap, the eliminated coverage gap, and no cost-sharing in the catastrophic phase all remain exactly as they are now.

Plan-level variation continues too. Premiums, formularies, pharmacy networks, and provider networks still differ by carrier and by county, and your healthcare needs still determine which plan fits.

What Should Medicare Beneficiaries Do Before Annual Enrollment

The annual enrollment period runs October 15 through December 7, and it is the window where these changes become your problem or your opportunity. Work through this before it opens:

• Read your Annual Notice of Change. It lists exactly what your plan is doing differently, and it arrives in September.
• Check your prescriptions against the formulary. Drug tiers move every year, and Part D plans change what they cover.
• Confirm your doctors and pharmacies. Provider networks shift, and a provider who participated last year may not next year.
• Spend your supplemental benefits. With the mid-year notice gone, nobody will remind you before the balance expires.
• Compare against Original Medicare. A Medicare Supplement and a standalone Part D plan are different structures worth pricing at least once.

Start in early October. Medicare beneficiaries who handle this well are the ones who read the notice when it arrives rather than the week before the deadline.

What a Licensed Agent Will Do With These Changes

Nobody sends you a summary of what the major Medicare changes in 2027 mean for your specific plan. A licensed agent reads the rule, then reads your plan, and tells you whether the two intersect.

Where the work happens:

• Translating the rule into your situation. Most of the 2027 changes affect what plans must do, and only some of them reach your coverage.
• Tracking your supplemental benefits. With mid-year notices gone, an agent who reviews your plan each fall catches unused benefits before they expire.
• Reading Star Ratings correctly. A simplified rating system means less signal, so comparing plans takes more than a star count.
• Running your prescriptions and doctors. Formularies and provider networks change annually regardless of what CMS does.

Agents are paid by the carriers, not by you, so the review costs nothing. What matters is finding someone who explains what changed and whether it affects you, rather than using the changes as a reason to switch you.

Get Help Reviewing Your Medicare Coverage

The major Medicare changes in 2027 make an annual review worth more than it used to be. Star Ratings tell you less, supplemental benefits carry tighter rules, and nobody will remind you mid-year about a benefit you have not used.

Senior Insurance Agency has helped Nevada families review Medicare coverage since 1986. A licensed Medicare professional can compare your current plan against the Medicare Advantage, Medicare Supplement, and Part D options available in your county.
