What the Latest CMS Rule Means for Medicare Beneficiaries

Medicare rules have a habit of arriving wrapped in hundreds of pages of government language.

The headlines promise lower costs, better coverage, improved quality, and simpler choices. Then beneficiaries are left wondering the only thing that really matters:

What does this mean for me?

On April 2, 2026, the Centers for Medicare & Medicaid Services issued its final Medicare Advantage and Medicare Part D rule for the 2027 coverage year.

The rule changes how Medicare evaluates plan quality, formalizes several important prescription-drug protections, tightens oversight of certain supplemental benefits, and changes some of the rules involving enrollment assistance and plan communications.

Most of the changes will affect coverage beginning January 1, 2027. That means beneficiaries should start seeing the practical results when 2027 plan information becomes available during the fall of 2026.

Some provisions could make Medicare easier to understand. Others may require beneficiaries to become even more careful about reading plan documents and comparing their options.

Here is what people with Medicare need to know.

The Rule Applies Mainly to Medicare Advantage and Part D

The latest rule focuses primarily on:

• Medicare Advantage plans
• Medicare Advantage plans that include prescription coverage
• Stand-alone Medicare Part D plans
• Medicare Cost Plans
• Certain supplemental benefits offered through Medicare Advantage

It does not replace Original Medicare, and it does not mean that everyone’s coverage will change in exactly the same way.

Medicare Advantage and Part D plans are offered by private insurance companies under contracts with Medicare. Each insurer still decides which plans to offer, which provider networks to use, which covered drugs to place on its formulary, and what premiums and cost-sharing amounts to charge within Medicare’s rules.

That means a national CMS rule may affect the structure of the program, but your actual benefits will still depend on your specific plan and ZIP code.

Our guide to Medicare plans available in your area explains why two people in different counties may see completely different choices.

Medicare Star Ratings Are Being Refocused

One of the biggest parts of the rule concerns Medicare Star Ratings.

Medicare rates Medicare Advantage and Part D plans on a scale of one to five stars. These ratings are meant to help beneficiaries compare plan quality.

A five-star plan is supposed to represent stronger overall performance than a lower-rated plan. However, the rating system has become complicated, with plans measured on dozens of clinical, administrative, customer-service, medication, and patient-experience factors.

CMS is now removing 11 measures that it says are mainly administrative or do not meaningfully help beneficiaries distinguish one plan from another. CMS is also adding a new Medicare Advantage measure involving depression screening and follow-up care.

The goal is to put more emphasis on:

• Clinical outcomes
• Patient health
• Member experience
• Access to care
• Meaningful differences between plans

That sounds reasonable. Nobody chooses a health plan because it files especially attractive paperwork.

However, beneficiaries should not treat Star Ratings as the only measurement that matters.

A highly rated plan may still exclude your doctor, place your medication on an expensive tier, require prior authorization for an important service, or have a higher annual out-of-pocket limit than another available option.

Star Ratings can be useful, but they are only one part of the decision.

When choosing coverage, it is still essential to compare:

• Your doctors and hospitals
• Your medications
• Your pharmacy
• The plan’s premium
• Copays and coinsurance
• The annual out-of-pocket limit
• Referral and prior authorization rules
• Extra benefits you are actually eligible to use

Our step-by-step Medicare plan selection guide explains how to evaluate those factors together.

The Part D Coverage Gap Is Officially Gone

The latest CMS rule formally places the redesigned Medicare Part D benefit into federal regulations for 2027 and future years.

One of the most important changes is the elimination of the old Part D coverage gap, commonly known as the “donut hole.”

For years, beneficiaries moved through several confusing stages of drug coverage:

1. The deductible
2. Initial coverage
3. The coverage gap
4. Catastrophic coverage

Each stage could change what the beneficiary paid at the pharmacy.

The redesigned Part D benefit removes the coverage-gap phase and creates a simpler structure. The rule also formalizes the annual out-of-pocket limit and removes additional beneficiary cost sharing after a person reaches the catastrophic phase.

This does not mean prescriptions become free from the beginning of the year.

Beneficiaries may still face:

• A plan deductible
• Tiered copayments
• Coinsurance
• Formulary restrictions
• Prior authorization
• Step therapy
• Quantity limits
• Different costs at preferred and standard pharmacies

The protection is that there is now a limit on what a beneficiary must pay out of pocket for medications covered under the Part D benefit.

For 2026, the annual Part D out-of-pocket limit is $2,100. The 2027 amount may be adjusted under the annual Medicare formula, so beneficiaries should check the official figure when 2027 plan information is released.

The Rule Does Not Guarantee That Every Drug Is Covered

This point deserves emphasis.

An annual Part D spending limit only applies to medications that count under your Part D coverage.

It does not force every plan to cover every prescription.

Each Part D plan continues to maintain its own formulary, which is the plan’s list of covered drugs. Plans may also place medications on different tiers or require approval before they will pay.

For example, one plan may cover your medication with a modest copayment. Another may place the same drug on a specialty tier. A third may require you to try a less expensive alternative first.

That is why the monthly premium tells only part of the story.

A plan with a low premium can become extremely expensive when your medications are added. A plan with a somewhat higher premium may produce lower total annual costs.

Beneficiaries should compare plans using:

• The exact medication name
• The dosage
• How frequently it is taken
• The preferred pharmacy
• Whether mail order is desired

Medicare Advantage Supplemental Benefits Must Become More Transparent

Many Medicare Advantage plans advertise supplemental benefits such as:

• Healthy-food allowances
• Over-the-counter benefits
• Transportation
• Home-support services
• Meal benefits
• Fitness memberships
• Benefits for certain chronic conditions

Some of these benefits can be valuable.

The problem is that advertisements may make them sound broader or easier to obtain than they really are.

Certain benefits are known as Special Supplemental Benefits for the Chronically Ill. To qualify, an enrollee must generally meet specific medical and plan eligibility requirements.

Under the new CMS rule, Medicare Advantage plans must publicly post the eligibility criteria they develop for these chronic-condition benefits.

This is a meaningful improvement.

A beneficiary should be able to determine before enrolling whether a widely advertised food, utility, transportation, or support benefit is actually available to that person.

The important question is not:

“Does the plan advertise a grocery benefit?”

The better questions are:

“Do I qualify for it?”

“How much is it?”

“What can I purchase?”

“Where can I use it?”

“How often is it funded?”

A benefit that looks impressive in a television commercial may be worthless to someone who does not meet the eligibility rules.

Supplemental-Benefit Debit Cards Will Face Clearer Rules

Some Medicare Advantage plans administer supplemental benefits through debit-style cards.

These cards may be used for covered over-the-counter items, food benefits, utilities, or other approved services, depending on the plan and the beneficiary’s eligibility.

CMS is establishing clearer rules for these cards. They must be electronically connected to covered items and services so eligibility can be checked at the point of sale. Cards must also be limited to the applicable plan year.

The purpose is to reduce confusion, misuse, fraud, and transactions involving items that are not actually covered.

For beneficiaries, the practical lesson is simple:

Do not assume a benefit card works like ordinary cash.

Before using one, confirm:

• Which stores accept it
• Which items are eligible
• When the balance expires
• Whether unused funds roll over
• Whether medical eligibility is required
• Whether the benefit changes during the year

Keep receipts and check the balance regularly.

And remember that a large card allowance should never be the sole reason for choosing a Medicare plan.

Doctors, hospitals, prescriptions, and maximum out-of-pocket exposure are usually more important than a flashy card benefit.

Mid-Year Notices About Unused Benefits Are Being Eliminated

Under earlier requirements, Medicare Advantage plans had to send certain mid-year notices reminding members about supplemental benefits they had not used.

CMS is rescinding that requirement for 2027.

The stated purpose is to reduce administrative burden.

However, this change means beneficiaries may receive fewer reminders about benefits that remain available to them.

That places more responsibility on the member.

At the beginning of each year, make a written list of every supplemental benefit included in your plan. Check it again every few months.

Your list might include:

• Dental
• Vision
• Hearing
• Transportation
• Fitness
• Over-the-counter items
• Food benefits
• Meal delivery
• Personal emergency response systems
• In-home support

Insurance companies are not known for sending someone to your front door and insisting that you use every dollar available to you.

You may have to keep track yourself.

Rules for Speaking With Agents and Brokers Are Changing

CMS is also removing some restrictions involving the time and manner in which beneficiaries may have conversations with licensed insurance agents and brokers.

The goal is to give beneficiaries greater flexibility in obtaining plan information.

That does not mean every marketing safeguard disappears.

Agents and insurers must still follow Medicare marketing rules, and beneficiaries should remain cautious about unsolicited calls, misleading advertisements, high-pressure sales tactics, and promises that sound too good to be true.

Never provide your Medicare number, Social Security number, banking information, or other personal information to an unknown caller.

You are entitled to compare coverage privately and take time to make a decision.

Our article Why More Seniors Are Choosing to Enroll in Medicare Online explains how online comparison can reduce pressure while allowing beneficiaries to review their options at their own pace.

More Money Is Going Into Medicare Advantage—but Benefits Are Not Guaranteed

Separate from the final rule, CMS announced that Medicare Advantage plan payments are projected to increase by an average of 2.48% in 2027, representing more than $13 billion in additional payments to plans.

That does not mean every beneficiary will receive lower premiums or richer benefits.

Insurance companies use Medicare payments to construct their plans. Actual benefits will depend on medical costs, competition, risk-adjustment changes, prescription expenses, provider contracts, and each insurer’s business decisions.

A plan may:

• Add benefits
• Reduce benefits
• Change copayments
• Adjust its network
• Change its drug formulary
• Increase its premium
• Leave a county entirely

Beneficiaries will not know the complete effect until individual 2027 plan details are released.

That is why claims such as “Medicare Advantage benefits are increasing” should be treated cautiously.

Payments to insurers are not the same as benefits guaranteed to members.

What Beneficiaries Should Do Before 2027

The new rule does not require most beneficiaries to take immediate action in July 2026.

However, preparation should begin before the Medicare Annual Enrollment Period, which runs from October 15 through December 7.

Before comparing plans:

1. Make a current medication list.
2. Confirm your preferred doctors and hospitals.
3. Review the plan’s Annual Notice of Change.
4. Check the 2027 formulary.
5. Compare total expected costs, not just premiums.
6. Verify eligibility for supplemental benefits.
7. Check the maximum out-of-pocket limit.
8. Review prior authorization requirements.
9. Confirm that your pharmacy remains preferred.
10. Compare your current plan with other available choices.

The Bottom Line

The latest CMS rule includes several potentially helpful changes.

Part D financial protections are being permanently incorporated into Medicare regulations. Star Ratings are being refocused toward health outcomes and meaningful plan differences. Supplemental-benefit eligibility should become more transparent. Debit-card benefits will face clearer controls.

But the rule does not make every Medicare Advantage or Part D plan equally good.

Plans can still differ dramatically in:

• Doctor networks
• Covered drugs
• Premiums
• Copayments
• Prior authorization
• Supplemental benefits
• Out-of-pocket limits
• Pharmacy costs

The most important protection remains an annual review based on your own health needs.

Do not assume that the plan you have today will remain the best plan for 2027.

Medicare rules change.

Insurance plans change.

Your medications and medical needs may change too.
