Medicare changes every year, and the shifts finalized for 2027 reach nearly every part of the program. The Centers for Medicare & Medicaid Services (CMS) published a final rule in April 2026 that revises the Medicare Advantage program, the Medicare Part D prescription drug benefit, and Medicare cost plans. For beneficiaries, the updates affect premiums, prescription drug spending, quality ratings, and plan availability. For employers, the changes create new questions about retiree coverage, benefits communication, and how workers approaching age 65 should prepare.
The Biggest Medicare 2027 Changes to Track
CMS framed the Contract Year 2027 rule as a broad package of policy and technical changes that affect the private plans serving Medicare beneficiaries. The agency is codifying adjustments for 2027 and beyond, including the elimination of the Part D coverage gap phase and the introduction of a reduced annual out-of-pocket limit for prescription drug coverage.
A quick look at what is shifting for 2027:
- The estimated Medicare Part B monthly premium rises from $202.90 in 2026 to about $221.00 in 2027.
- The Part D coverage gap phase is eliminated, and a reduced annual out-of-pocket limit is established.
- Medicare Advantage plans receive an approximate $26 billion payment increase in 2027.
- Some Medicare Advantage plans will no longer be offered in 2027, and reports show more than one million seniors could be affected.
- Agents no longer need to wait 48 hours after collecting a Scope of Appointment before meeting with beneficiaries.
- The Annual Enrollment Period runs from October 15 to December 7.
These changes arrive together, so they should be reviewed together. Premium movement, benefit redesign, and plan availability all shape the decisions that retirees make for the coming plan year.
Part B Premiums in 2027 Keep Moving Upward
Part B covers outpatient care, doctor visits, and medical supplies, and most beneficiaries pay a monthly premium for it. The standard Part B monthly premium is $202.90 in 2026. For 2027, estimates place the premium at about $221.00 per month. The increase is significant on its own, and CMS expects larger premium increases to follow in 2028 and beyond.
Official premium amounts are usually announced closer to the plan year, so the 2027 figure has not been locked in as a final rate. Beneficiaries who create a retirement budget should plan for the increase and confirm the exact amount when it is released. Employers that reimburse or subsidize Part B costs for retirees should also factor the climb into their benefit projections.
Medicare Advantage and Part D Changes for 2027
The biggest policy shifts in the 2027 final rule are inside Medicare Advantage and Part D. The rule revises the Medicare Advantage program, the Part D prescription drug benefit, and Medicare cost plans. For most beneficiaries, the practical effects show up in plan premiums, cost-sharing, quality ratings, and the total amount they pay for drugs.
The Part D Coverage Gap Phase Is Eliminated
CMS is codifying the elimination of the Part D coverage gap phase for 2027 and beyond. In earlier years, beneficiaries who reached certain spending thresholds entered the coverage gap and faced higher out-of-pocket costs for their prescriptions. Removing that phase simplifies the benefit structure for people who rely on brand-name and specialty medications.
Beneficiaries Get a Reduced Annual Out-of-Pocket Limit
The same rule establishes a reduced annual out-of-pocket limit for Part D prescription drug coverage. That cap gives people with high medication costs a clearer view of their maximum financial exposure for the year. For anyone taking expensive maintenance drugs, pairing the coverage gap elimination with the new out-of-pocket limit makes drug spending easier to predict.
Star Ratings Are Reworked for Part C and Part D Plans
The 2027 Medicare changes also rework the star ratings used for Medicare Advantage and Part D plans. CMS says some administrative-based measures will be removed from the rating system. Star ratings are the publicly available quality scores that help beneficiaries compare plans, and any shift in what gets measured can change which plans earn the highest marks.
Some Medicare Advantage Plans Will Disappear in 2027
Plan availability is changing as well. Some Medicare Advantage plans currently on the market are being eliminated in 2027, and analyses estimate that more than one million seniors could be affected. A beneficiary whose plan is discontinued will not be able to renew it for the new plan year, so comparing replacement plans before the enrollment deadline becomes essential.
Medicare Advantage Payments Rise in 2027
Medicare Advantage plans will receive an approximate $26 billion payment increase in 2027. The rate announcement for calendar year 2027 turned out to be favorable for insurers, moving the program from what looked like a flat funding year to a stronger one. Analysts have pointed to the higher-than-expected payment increase as one of the defining forces behind the 2027 plan landscape.
A larger payment to plans does not guarantee that premiums will drop or that benefits will improve. Each carrier decides how to use the additional funding. Still, the increase helps explain why Medicare Advantage remains a stable and competitive part of the Medicare program heading into the new plan year.
Marketing Rules Shift for Agents and Brokers
The 2027 final rule also rewrites the marketing rules that govern how agents, brokers, and third-party marketing organizations work with Medicare beneficiaries. The changes touch appointment-setting, marketing materials, and consumer protections, and they reshape how plan information reaches the public.
One of the most practical changes is the removal of the 48-hour waiting period after collecting a Scope of Appointment. Previously, agents could not hold an appointment until two days after the Scope of Appointment was collected. That waiting period is gone under the 2027 rules. The same final rule enhances some consumer protections while rolling back others, so beneficiaries and the professionals who advise them need to understand the new boundaries.
The 2027 Annual Enrollment Period
For 2027 coverage, Medicare’s Annual Enrollment Period runs from October 15 to December 7. During this window, beneficiaries can join a Medicare Advantage plan, switch to a different Advantage plan, or drop their current plan and return to Original Medicare. They can also join, switch, or drop a stand-alone Part D prescription drug plan.
People whose current plans are being eliminated should treat this window as their main chance to lock in coverage for the new year. Waiting until after the deadline can limit available options and create gaps in coverage.
What Employers Should Know About Medicare 2027 Changes
Employers do not need to sponsor Medicare plans to feel the effects of these changes. Workers approaching age 65 must decide whether to stay on a group health plan, enroll in Medicare, or carry both. When Part B premiums rise and Part D rules shift, employees need updated guidance to make that decision well.
For employers that offer retiree health benefits or reimburse Medicare premiums, the 2027 updates carry direct cost implications. A higher Part B premium means a higher reimbursement cost for any employer that covers it. Retirees who lose their current Medicare Advantage plan will need support comparing the plans that remain available in their area.
Timing matters more than ever. Employers should help eligible employees and retirees prepare for the Annual Enrollment Period, which runs from October 15 to December 7. Sending reminders, sharing plan updates, and making a benefits adviser available can prevent the confusion that often surrounds a year with this many program changes.
A benefits broker can bridge the gap between group health coverage and Medicare. The 2027 changes touch multiple parts of the program at once, and the connection between Part B premiums, Part D structure, and Medicare Advantage plan availability is not always easy to follow. For small and midsize employers, working with an adviser who understands both commercial insurance and Medicare simplifies the process for everyone involved.
