Attribution, Benchmarks, and Quality: Three Drivers of MSSP Performance

In the Medicare Shared Savings Program (MSSP), success is often simplified to a single idea: beat the benchmark. While technically correct, this view is incomplete.

Organizations that focus only on cost performance overlook the three factors that ultimately determine financial outcomes: attribution, benchmarks, and quality. These are not independent concepts. They function as an integrated system that defines accountability, establishes financial targets, and determines how much value is realized.

Attribution Defines Accountability

Attribution determines which patients an organization is responsible for. While this may appear straightforward, it is one of the most dynamic elements of value-based care. Populations shift continuously based on patient behavior, provider relationships, and contract design. In some models, patients are assigned in advance. In others, attribution is finalized after care is delivered.

As a result, organizations are not managing a fixed population. They are managing a population that evolves over time.

High-performing organizations treat attribution as a strategic lever. They focus on strengthening relationships with patients already receiving care within their network, improving alignment between patients and providers, and engaging patients whose care patterns suggest an opportunity to build a more consistent primary care relationship.

"Without a clear and continuously updated understanding of attribution, organizations are managing the wrong patient list. Everything downstream of that is expensive noise."

Benchmarks Define What Success Looks Like

Benchmarks establish the financial target. In MSSP, benchmarks represent the expected cost of care for the attributed population and are established by CMS using historical expenditures, regional cost trends, and risk adjustment methodologies. Performance is measured by comparing actual cost against that target.

Because financial reconciliation occurs after the performance year, organizations cannot treat benchmark performance as a retrospective exercise. Successful organizations continuously monitor utilization patterns, cost drivers, and emerging trends throughout the year in order to identify risks and adjust strategy in real time.

Many operational and clinical interventions take time to influence utilization, quality outcomes, and financial performance. As a result, organizations that consistently perform well continuously reassess priorities, refine interventions, and adapt their approach throughout the performance year.

The Overlooked Reality: Quality Determines Financial Outcomes

This is where many organizations fall short. Reducing cost below the benchmark does not guarantee financial success.

Quality performance directly impacts whether savings are earned and how much is retained. Organizations must meet quality thresholds to be eligible for shared savings, and quality scores often influence the percentage of savings they receive.

As a result, an organization can improve cost performance and still underperform financially if quality is not managed effectively.

Improving population health and quality performance is fundamental to achieving sustainable financial results. Preventing avoidable admissions, improving chronic disease management, managing transitions of care, and closing care gaps are not only clinical objectives. They directly influence utilization, cost, patient outcomes, and overall financial performance.

Why These Three Must Be Managed Together

1. 01Attribution defines who is included. The right patient list is the precondition for every downstream investment.
2. 02Benchmarks define what success looks like financially. The target is set by CMS; your job is to manage against it in real time, not retrospectively.
3. 03Quality determines how much of that success is ultimately realized. Cost performance without quality performance is a discount on your own savings.

When these elements are managed in isolation, priorities become fragmented and impact is diluted. When they are managed together, organizations can focus on the patients, interventions, and workflows that will most meaningfully improve population health outcomes while also influencing financial performance.

The goal of value-based care is not simply reducing cost. It is improving outcomes, strengthening care coordination, preventing avoidable utilization, and helping populations become healthier over time. Financial performance is meant to reflect the effectiveness of those efforts, not replace them.

Organizations that consistently succeed in MSSP understand that population health improvement and financial performance are deeply connected. Sustainable savings are typically achieved through better care, not less care.

The Bottom Line

Value-based care performance is not driven by cost alone. It is driven by how effectively an organization aligns attribution, benchmarks, and quality into a unified approach to managing population health and financial outcomes. Organizations that understand and operationalize this alignment consistently outperform those that focus on metrics without context.
