America’s $400 billion Medicare Advantage market is showing cracks in unexpected places.
The numbers don’t lie, but they do tell a complicated story. Four years of Medicare Advantage star rating data reveal an industry grappling with a fundamental tension: how to deliver consistent quality care while managing explosive growth across an increasingly complex healthcare landscape.
The Centers for Medicare & Medicaid Services (CMS) star ratings represent more than bureaucratic scorekeeping. They determine billions in quality bonus payments and shape how 26 million Americans choose their health coverage. More importantly, they offer a window into whether Medicare Advantage, which now covers 48% of Medicare beneficiaries, is delivering on its promise of better coordinated, higher quality care.
The answer, based on performance trends from 2022 through 2025, is nuanced and troubling.
Perhaps most concerning is the steady erosion in preventive care measures. Breast and colorectal cancer screening averages have fallen from 3.9 stars in 2022 to approximately 3.4 stars in 2025. Diabetes management metrics, including crucial eye exams and blood sugar control, have declined by roughly half a star over the same period.
This isn’t a minor statistical blip. It represents a systemic failure in member engagement at precisely the moment when early intervention could prevent costly complications. The financial implications are staggering: each percentage point improvement in diabetic eye exams alone can prevent millions in downstream medical costs across a large Medicare Advantage population.
The decline suggests that rapid plan enrollment growth has outpaced the infrastructure needed to maintain meaningful member relationships. Plans have become proficient at acquiring members but struggle to keep them engaged in their own health management between acute episodes.
While preventive care deteriorates, post-acute care coordination is improving. Medication reconciliation, readmission reduction, and care transitions have climbed from the mid-2s to approximately 3.0-3.2 stars. Emergency department follow-up protocols show similar gains.
This split reveals something important about Medicare Advantage operations: plans excel at managing crises but struggle with prevention. They’ve built sophisticated systems to coordinate care after hospitalizations when stakes are high and workflows are standardized but haven’t translated this competence to routine wellness management.
The irony is profound. Medicare Advantage’s core value proposition is preventive care and care coordination, yet plans are succeeding at expensive reactive coordination while failing at cost-effective prevention.
Member satisfaction metrics tell their own story of institutional strain. “Getting Needed Care” and “Rating of Health Plan” show modest declines, while “Getting Care Quickly” remains stagnant around 3.1 to 3.4 stars. These aren’t dramatic drops, but they represent concerning trends in an industry built on customer satisfaction.
The pattern suggests that Medicare Advantage plans are becoming victims of their own success. As enrollment grows, maintaining the personal touch that originally differentiated them from traditional Medicare becomes increasingly difficult. Members are encountering longer wait times, more complex prior authorization processes, and less responsive customer service.
Appeals and complaints processing, which are often the first indicators of operational stress, also show similar warning signs. Slight declines in timeliness and decision review quality suggest that back-office operations haven’t scaled with membership growth.
What’s most striking about these trends is how they illuminate Medicare Advantage’s innovation challenges. An industry that has mastered actuarial science and risk adjustment seems to struggle with basic member engagement and preventive care delivery.
Part of the problem is technological. Most Medicare Advantage plans operate on legacy systems designed for claims processing, not member engagement. They can identify high-risk members with sophisticated algorithms but lack the digital infrastructure to engage those members consistently between doctor visits.
The solution isn’t more technology, but a better integration of existing systems. Plans need platforms that connect clinical data with member behavior, social determinants with care management, and provider networks with member preferences. The goal isn’t more data, but more actionable insights delivered at the point of member interaction. This is the foundational principle behind the blueBriX platform.
These performance trends have immediate financial implications. Quality bonus payments, which can represent 20% or more of a plan’s government revenue, are directly tied to star ratings. A plan that slides from 4 to 3.5 stars can lose hundreds of millions in bonus payments, as Elevance Health recently discovered in their high-profile legal battle over rating methodology.
More importantly, declining performance threatens Medicare Advantage’s political sustainability. The program’s rapid growth has created scrutiny from policymakers concerned about costs and quality. Consistent declines in basic preventive care measures provide ammunition for critics who argue that Medicare Advantage plans prioritize profits over patient outcomes.
The internal tensions revealed in star ratings are not isolated. They ripple across the entire Medicare Advantage ecosystem, impacting key stakeholders in ways that compound the challenge for plans.
This confluence of pressures from regulators, providers, and members makes the current Medicare Advantage landscape a high-stakes, high-risk environment. The question is no longer just how to grow, but how to do so sustainably while meeting the demands of every party in the ecosystem.
The data makes one thing clear: the current Medicare Advantage system, while a success in growth, is not optimized for sustainable, high-quality care. To reverse these troubling trends and secure the program’s future, a fundamental shift in strategy is required. This isn’t just about small tweaks; it’s about rebuilding the foundation in direct response to the market’s most pressing policy discussions.
This blueprint for a better system is not theoretical. The technology to achieve it exists. The financial incentives are already in place. But are the industry leaders are ready to make the necessary investments to move from managing a troubled market to building a better one?
The Medicare Advantage plans that will thrive in the next decade are those that solve the coordination paradox: maintaining the personal engagement that drives preventive care while scaling the operational excellence that manages complex medical conditions.
This requires a fundamental shift in how plans think about member relationships. Instead of viewing members as actuarial risks to be managed, successful plans will treat them as individuals whose health outcomes directly impact long-term profitability. This means investing in the foundational work of member engagement, preventive care outreach, and seamless care coordination across all settings.
The technology exists. The financial incentives are aligned. The question is whether Medicare Advantage leadership will make the investments necessary to reverse concerning trends before they become entrenched patterns.
The star ratings data suggests time is running short. In a market where 0.25 stars can mean hundreds of millions in lost revenue, declining performance isn’t just a quality problem but an existential threat.
