Avalere Report: Why CMMI Won't Match CBO's Medicare Savings Projections

The landscape of American healthcare financing is shifting beneath our feet,
driven by ambitious federal initiatives designed to curb spiraling costs. At
the heart of this transformation is the Center for Medicare and Medicaid
Innovation (CMMI), established to test new payment and service delivery
models. For years, policymakers and investors alike have relied on
Congressional Budget Office (CBO) projections to gauge the potential fiscal
impact of these models. However, a groundbreaking analysis by Avalere Health
has sent shockwaves through the industry, suggesting that CMMI will not
generate as much savings for Medicare as the CBO originally projected.

This divergence between expectation and reality is not merely a statistical
footnote; it represents a fundamental recalibration of how we understand
value-based care. As stakeholders digest the Avalere findings, the
implications for Medicare beneficiaries, healthcare providers, and the federal
budget are profound. This deep dive explores the mechanics behind the
shortfall, the specific models under scrutiny, and what this means for the
future of healthcare reform.

The Disconnect: CBO Optimism vs. Real-World Data

The Congressional Budget Office has historically served as the gold standard
for fiscal forecasting. Their projections regarding CMMI models were built on
the premise that shifting from fee-for-service to value-based care would
rapidly reduce unnecessary spending while maintaining or improving quality.
The CBO anticipated that successful pilot programs would scale quickly,
generating billions in savings over a decade.

However, the Avalere report highlights a critical gap between theoretical
modeling and operational execution. The core of the issue lies in the
complexity of implementation. While the CBO models assumed a certain level of
provider adoption and efficiency gain, real-world data suggests that the
transition is slower, more costly, and less effective at scale than
anticipated. The Avalere analysis indicates that CMMI will not generate as
much savings for Medicare as CBO projected because the structural incentives
required to change provider behavior are more nuanced than simple payment
adjustments.

Key Factors Driving the Savings Shortfall

Several interconnected factors contribute to this projected deficit in
savings. Understanding these elements is crucial for anyone tracking
healthcare policy or managing healthcare assets.

• Slower-than-Expected Adoption Rates: Many providers, particularly smaller independent practices, lack the capital and technical infrastructure to participate fully in advanced alternative payment models (APMs). This limits the pool of participants and dilutes the aggregate savings.
• Implementation Costs: The upfront investment required for data analytics, care coordination staff, and IT integration often outweighs the initial bonus payments or shared savings, discouraging sustained participation.
• Risk Aversion: Providers are increasingly hesitant to take on downside risk. Without broad participation in two-sided risk models, the potential for significant cost reduction is capped.
• Model Complexity: The administrative burden of complying with multiple, overlapping CMMI initiatives creates friction that reduces overall efficiency.

Deep Dive: Which Models Are Underperforming?

The Avalere report does not paint all CMMI initiatives with the same brush.
Certain models have shown promise, while others have struggled to move the
needle on national spending. The discrepancy is most pronounced in models
targeting chronic care management and population health, where the timeline
for realizing savings often exceeds the evaluation periods used by the CBO.

The Challenge of Accountable Care Organizations (ACOs)

Accountable Care Organizations were touted as the flagship vehicle for value-
based care. The premise was simple: coordinate care to keep patients healthy,
and share the savings. Yet, the data suggests that while ACOs have improved
quality metrics, the net savings to the Medicare Trust Fund have been modest.
The Avalere analysis points out that many ACOs are generating savings that are
reinvested into the organization rather than returned to Medicare, or the
savings are offset by increased utilization in other areas.

Bundled Payments and Episode-Based Care

Similarly, bundled payment models, which set a fixed price for an episode of
care (such as a hip replacement), have faced headwinds. Providers have
reported difficulties in defining the scope of the bundle and managing post-
acute care variability. Consequently, the volume of episodes participating in
these mandatory and voluntary models has not reached the thresholds necessary
to drive the macro-level savings the CBO predicted.

The Broader Implications for Medicare Solvency

The revelation that CMMI will not generate as much savings for Medicare as CBO
projected carries weighty consequences for the long-term solvency of the
Medicare program. The Medicare Trustee Reports have increasingly relied on
these projected savings to extend the projected insolvency date of the
Hospital Insurance Trust Fund. If these savings fail to materialize at the
expected rates, the timeline for potential trust fund exhaustion could
accelerate.

This reality forces a difficult conversation among legislators. It suggests
that voluntary innovation alone may be insufficient to bend the cost curve.
Policymakers may need to consider more aggressive regulatory interventions,
mandatory participation rules, or a reevaluation of the benefit structure
itself. Furthermore, it places pressure on the Centers for Medicare & Medicaid
Services (CMS) to streamline existing models and reduce the administrative
burden that stifles provider engagement.

Strategic Takeaways for Healthcare Leaders

For healthcare executives and investors, the Avalere findings serve as a
cautionary tale and a strategic roadmap. The era of low-hanging fruit in
value-based care is likely over. Future success will require a more
sophisticated approach to risk management and population health.

• Focus on Infrastructure: Organizations must prioritize robust data interoperability and analytics capabilities to identify high-risk patients before costs escalate.
• Collaborative Networks: Smaller providers should consider joining larger networks or IPAs to share the costs of innovation and risk mitigation.
• Patience with ROI: Stakeholders must adjust their return-on-investment timelines, recognizing that true transformational change in healthcare delivery takes years, not quarters.
• Advocacy: Industry leaders must actively engage with CMS to refine model designs, ensuring they are practical and financially viable for a broader range of participants.

Conclusion: A Pivot Point for Policy

The Avalere report serves as a critical reality check for the healthcare
industry. The assertion that CMMI will not generate as much savings for
Medicare as CBO projected is not an indictment of value-based care itself, but
rather a signal that the current execution strategy requires refinement. The
path to sustainable healthcare financing is paved with complexity, requiring
patience, precision, and perhaps a willingness to rethink the mechanisms of
innovation. As the gap between projection and performance narrows, the actions
taken by CMS and Congress in the coming years will define the future of
Medicare for generations to come.

Frequently Asked Questions (FAQ)

What is the main finding of the Avalere report regarding CMMI?

The primary finding is that the Center for Medicare and Medicaid Innovation
(CMMI) is unlikely to achieve the level of cost savings for the Medicare
program that the Congressional Budget Office (CBO) had previously projected.
This is due to slower adoption rates, high implementation costs, and the
complexity of current payment models.

Why did the CBO overestimate the savings from CMMI models?

The CBO's projections were largely based on theoretical models assuming rapid
scaling and high provider participation. They did not fully account for the
operational friction, administrative burdens, and risk aversion that providers
face in the real world, leading to an overestimation of achievable savings.

Which CMMI models are most affected by these findings?

Models focusing on Accountable Care Organizations (ACOs) and bundled payments
for chronic conditions and episodic care are most affected. These models
require significant infrastructure and coordination, which has proven
difficult to scale quickly enough to meet aggressive savings targets.

How does this impact Medicare beneficiaries?

While the immediate impact on beneficiaries may not be visible, long-term
implications could include potential changes to premium structures, benefit
coverage, or access to certain providers if the financial pressure on the
Medicare Trust Fund increases due to missed savings targets.

What should healthcare providers do in response to this news?

Providers should focus on strengthening their data analytics capabilities,
forming strategic partnerships to share risk, and engaging more deeply with
CMS to provide feedback on model design. It is also a time to carefully
evaluate which value-based contracts align best with their operational
strengths.
