For years, many Medicare Advantage (MA) products were designed to serve broad populations with relatively standardized benefits and care models. That approach worked when member needs were more predictable and the market was less segmented, but the MA population is changing in meaningful ways, and quickly.

Beneficiaries enrolling in MA today are older and more clinically complex. Many have multiple chronic conditions, functional limitations, or significant social needs that require more coordinated and sustained support. At the same time, high-need populations, like dual eligibles, represent a growing share of MA enrollment.

Layered on top of these demographic shifts are the lingering effects of the COVID-19 pandemic. After the rebound from deferred care, many plans expected utilization to normalize. Instead, elevated utilization across inpatient, outpatient, post-acute services, and pharmacy has proven more persistent than anticipated.

Taken together, these trends are reshaping the risk profile and cost structure of MA membership.

The result is a growing mismatch between member needs and traditional “one-size-fits-all” product designs. Plans that continue to rely on broad-based products risk misaligned benefits, ineffective care management, and increasing financial volatility.

In today’s MA environment, a population-specific strategy is no longer a differentiator; it’s becoming table stakes for sustainable performance. In the next phase of MA, success will depend less on enrollment growth and more on whether plans have the strategies and care models needed to manage an increasingly complex population with predictability.

Why Now?

Several structural shifts are accelerating the need for more targeted MA strategies:

  • The MA population is aging and becoming more frail. As enrollment grows, plans are increasingly serving beneficiaries with greater clinical complexity, functional limitations, and social support needs – populations that require more tailored care models and benefits.
  • Utilization patterns remain elevated following the pandemic. The rebound from deferred care drove increases across many services, and many plans are finding those trends have proven sticky. Compounding the issue, healthcare prices have increased along with general inflation, and GLP-1 utilization continues to rise. Sustained high utilization puts pressure on the MLR and makes it even more important to focus resources on the populations driving the greatest need.
  • High-need populations are becoming more visible in plan data. When plans analyze utilization, care needs, and social risk, distinct clusters of members often emerge whose needs differ meaningfully from the broader population, particularly dual eligibles and members with complex chronic conditions.
  • MA shoppers are more sophisticated, and enrollment tools are improving. Increased transparency and simplification of the MA shopping experience is a top priority for policy makers, member organizations, and plans. Together with new innovations in the broker space and the fact that today’s MA members are more comfortable with technology, offering meaningful benefits and care models to MA members willing to shop is an imperative.
  • The MA program now offers more tools to support targeted approaches. Special Needs Plans (SNPs), Special Supplemental Benefits for the Chronically Ill (SSBCI), and more sophisticated care management models give plans new ways to design population-specific strategies. But these tools only deliver value when used as part of a deliberate population strategy.

Together, these dynamics mean that simply offering generalized MA products with add-on programs will be insufficient to ensure strong plan performance. Managing actuarial risk and delivering quality outcomes requires a new strategy. Plans must increasingly define which populations they are trying to serve and design products, benefits, and care models around those populations. Organizations that fail to do so risk managing increasingly complex populations with strategies built for a very different MA market.

Moving From One-Size-Fits-All to Population-Specific Strategy

As MA plans rethink their MA strategy and seek MLR predictability and high-quality performance, the central question should be: How do we organize our products and care models around the populations we serve?

The answer is rarely just analytical. It often reflects a plan’s operational capabilities, provider relationships, and appetite for product innovation. In practice, plans can pursue different pathways, with each one reflecting a different level of effort and approach to aligning populations and product design:

  • Align plan design to defined eligibility categories
  • Segment based on geography and market
  • Customize care models within a single plan

The challenge for many plans isn’t identifying these pathways. It’s determining which approach best aligns with their population, market position, and operational capabilities.

PATHWAY #1: Align Plan Design with Distinct Eligibility-Based Populations

Many plans begin by analyzing their membership based on utilization, care needs, and social risk to determine whether meaningful populations align with existing eligibility categories. For example, plans often find that their highest-need members are concentrated among dual eligibles. In these cases, expanding or strengthening a Dual Eligible Special Needs Plan (D-SNP) may provide the most effective platform for delivering tailored benefits and care models. Similarly, members with specific chronic conditions may align well with Chronic Condition Special Needs Plans (C-SNPs). When population needs clearly map to existing program structures, specialized products can be a powerful way to deliver more targeted care.

However, simply launching a SNP is not the strategy. Many plans underestimate the operational work required to make these products successful. Effective SNP strategies require alignment across product design, care models, provider partnerships, and supplemental benefits. Without that alignment, plans risk creating specialized products that do not meaningfully change care delivery or outcomes. Plans that succeed in this space treat SNPs not just as product offerings, but as platforms for delivering population-specific care models.

Plans that are comfortable launching new products and building specialized care models often gravitate toward this approach, particularly when high-need populations such as dual eligibles represent a significant share of membership.

PATHWAY #2: Segment Based on Geography or Local Market Dynamics

In some cases, geography may be the more meaningful lens. Member characteristics, provider networks, and community resources vary significantly across markets. Certain regions may have higher concentrations of dual eligibles, greater social risk, stronger appetite for risk-based contracting, or distinct utilization patterns.

In these cases, plans may choose to tailor benefits, network and partnerships, or care programs to local conditions rather than relying on a uniform national strategy. This may include market-specific benefit designs, localized community partnerships, or provider collaborations designed to address the needs of specific member populations.

This approach can be particularly attractive for plans with strong local market presence or deep provider partnerships that allow them to tailor benefits and programs to specific communities.

PATHWAY #3: Customize Care Models Within a Single Plan

Some plans face structural constraints that make it difficult to segment populations into separate products. Risk pool considerations, enrollment size, or geographic structure may require that members remain within a single plan.

In these cases, plans may consider targeted care programs within an existing plan chassis, using tools like SSBCI benefits, enhanced care management, and specialized provider partnerships. These programs allow plans to address the needs of specific populations while maintaining a unified plan structure. For some organizations, this approach serves as a stepping stone toward more specialized products such as C-SNPs. However, designing differentiated care models within a single plan can be operationally complex. In many cases, plans ultimately find that defining a discrete product for a specific population is simpler than building multiple care models inside one plan.

Plans that prefer to maintain a unified product structure often pursue this path, focusing on building more sophisticated care models within existing plans rather than creating new products.

A key decision plans need to make is how quickly to act. Population-specific strategy requires changes to product design, care models, provider partnerships, and operational infrastructure. Plans that delay these decisions often find themselves trying to retrofit programs into products that were never designed for the populations they now serve. Alongside this reality, these plans are likely experiencing unpredictable MLRs and, often, lower Star Ratings.

Questions Plans Should Be Asking Now

The shift toward a population-specific strategy raises a set of practical questions for MA plans. Leadership teams should consider:

  • Which populations within our membership have distinct care and social needs?
  • Do those needs align with existing eligibility-based products such as SNPs?
  • Are certain populations concentrated geographically?
  • Should we address these needs through new products, targeted programs within existing plans, or both?
  • Are there risk pool or enrollment considerations that require certain populations to remain in one product?
  • Do we have the operational capabilities to support differentiated care models?

The Bottom Line

Population-specific strategies are quickly becoming a must-have for MA plans. As the MA population grows older, more complex, and more diverse in its needs, and as utilization pressures persist, plans can no longer rely on one-size-fits-all products. They need strategies that better match care models, benefits, and programs to the differing needs of increasingly complex member populations.

Doing well takes more than launching a new product or adding a supplemental benefit. It requires aligning product design, care delivery, and operational capabilities around the populations driving the greatest need and cost.

Plans that get this right will be better positioned to manage complex populations, control utilization, and bring greater predictability to MLRs. The plans that don’t risk carrying forward strategies built for yesterday’s MA population into a very different future.

Medicare Advantage Is Now a Central Financing Mechanism for End-Stage Renal Disease Care

Nearly six years after Medicare Advantage opened up to people with end-stage renal disease, enrollment has climbed to nearly 280,000 beneficiaries, more than half of all Medicare beneficiaries with ESRD, and almost double what CMS originally projected. ATI Advisory's analysis of six years of Medicare data shows Medicare Advantage has become the primary way ESRD care gets paid for. Nephrologists, dialysis providers, and MA organizations are now negotiating payment rates, building provider networks, and navigating utilization management for a population that used to be financed almost entirely through fee-for-service.
