Every year, millions of Americans rely on Medicare Advantage for their primary healthcare coverage. As 2027 approaches, the data tells a compelling story—one of expanding benefits, evolving costs, and a more competitive marketplace than ever before. Knowing what the numbers actually say helps you move beyond marketing promises and make decisions grounded in evidence.
The Scale of Medicare Advantage in 2027
The Medicare Advantage plans 2027 program has grown into the dominant form of Medicare coverage in the United States. The Kaiser Family Foundation reports that enrollment crossed 33 million people in 2024 and continues to climb. Analysts project that by 2027, more than half of all Medicare beneficiaries will be covered under a Medicare Advantage plan—a milestone that would have seemed unlikely just 15 years ago.
This growth is partly driven by demographics. Roughly 10,000 baby boomers turn 65 every day, and a significant proportion of new enrollees are choosing Medicare Advantage plans 2027 over traditional Medicare from the start. Younger seniors, in particular, are drawn to the supplemental benefits and coordinated care models that many plans offer.
What Beneficiaries Are Actually Paying in 2027
Cost is always central to any coverage decision. The good news for 2027 enrollees is that average monthly premiums for Medicare Advantage plans remain relatively low. According to CMS data, the average projected Medicare Advantage premium for 2026 was approximately $17 per month—a figure expected to remain stable heading into 2027 for many plan types.
However, premiums alone tell an incomplete story. Deductibles, copayments, and out-of-pocket maximums vary widely between plans. Research from the Commonwealth Fund has shown that beneficiaries who fail to compare plans annually frequently overpay by hundreds—sometimes thousands—of dollars each year.
The Benefit Landscape: What Plans Are Offering
One of the defining features of Medicare Advantage is the range of supplemental benefits beyond what Original Medicare covers. For 2027, the most commonly offered extras include:
Dental coverage: Cleanings, X-rays, and in some cases restorative work
Vision benefits: Annual eye exams and an allowance for glasses or contact lenses
Hearing aids: A benefit Traditional Medicare does not cover at all
Fitness memberships: Access to gym networks and wellness programs
Transportation assistance: Rides to and from medical appointments
Over-the-counter allowances: Quarterly credits for health-related purchases
Not every plan offers every benefit, and benefit generosity often correlates with plan Star Ratings and geographic availability. Urban markets tend to see more competitive offerings than rural ones.
How CMS Star Ratings Influence Your Experience
The CMS Star Rating system is the federal government’s quality benchmark for Medicare Advantage plans. Plans are evaluated annually on dozens of metrics, including preventive care rates, chronic disease management, member satisfaction, and customer service responsiveness.
In 2027, the methodology has been updated to place greater emphasis on health equity measures and timely access to care. For enrollees, this means that a plan’s Star Rating is now a more accurate proxy for real-world performance than in previous years. Choosing a 4- or 5-star plan meaningfully reduces the likelihood of claim disputes, denied authorizations, and poor care coordination.
Five Data Points Worth Knowing Before You Enroll
Plans with Star Ratings of 4 or above enroll approximately 80% of all Medicare Advantage beneficiaries, according to CMS.
Prescription drug costs account for the largest share of out-of-pocket spending for most Medicare Advantage enrollees.
More than 99% of Medicare-eligible individuals have access to at least one Medicare Advantage plan in their area.
The average enrollee has access to 43 Medicare Advantage plans in their county, according to KFF.
Switching plans during open enrollment—rather than auto-renewing—is one of the most effective ways to reduce annual healthcare costs.
Use the Data to Drive Your Decision
Evidence should anchor your enrollment decision. Compare plans using Medicare.gov’s official Plan Finder tool, cross-reference Star Ratings, and model your expected annual costs across your top choices before committing. The plan that worked well in 2026 may not be the best fit for 2027—benefit structures change, and so do your needs.
