ACOs in Medicare: ACO REACH's Impact and ACO LEAD's Future

The ACO REACH initiative is slated to conclude this year, having generated significant savings of $988 million for Medicare in 2024, as illustrated by recent CMS data. ACO REACH, which succeeded Medicare's prior direct contracting model in 2023, engaged healthcare providers organized into Accountable Care Organizations (ACOs) in managing financial risk to optimize patient care. Despite modifications aimed at increasing involvement, the program struggled to maintain provider participation over concerns about financial risks.

As ACO REACH approaches its 2026 expiration, CMS has introduced a successor model, ACO LEAD, addressing prior provider apprehensions. Despite challenges, ACO REACH's effectiveness reportedly improved, based on updated CMS metrics, prompting discussions about its impact on Medicare's financial health.

In 2024, ACOs witnessed an enhanced quality score, rising from 79.42% in 2023 to 81.11%. This improvement indicates progress in reducing hospital readmissions and ensuring timely follow-up care, with assessments graded on a 100% scale. Even with varied individual results, ACOs collectively advanced Medicare savings, with notable successes from ATLAS IPA in New York and ACO Physicians Healthcare Collaborative in North Carolina.

However, not all ACOs achieved positive outcomes. CVS and Vytalize Health reported significant losses, with CVS's losses at $69.5 million, and Vytalize Health noting $99.7 million in losses, presenting net savings rates of -2.1% and -4.2%, respectively. These losses underscore the challenges of managing larger beneficiary groups within value-based models. Comparatively, other ACOs experienced lesser financial strains.

The National Association of ACOs recognized the robust performance of ACO REACH in 2024. NAACOS CEO Emily Brower highlighted the model's success and its beneficial impact on high-needs populations, expressing optimism for the forthcoming ACO LEAD model's potential.

ACO LEAD, anticipated to launch in 2027, aims to refine Medicare's value-based care through improved benchmarks, prospective payment systems, and equitable participation opportunities for diverse provider types. Simultaneously, CMS plans to enhance oversight of Medicare Advantage plans, investing in technology and expanding its medical coding team, while the FDA seeks stricter compliance in drug advertisements.
