Collaborative Health Systems Achieves $20 Million in Savings During Last Year of Next Generation ACO Program

TAMPA, Fla. (Dec. 12, 2022) Collaborative Health Systems (CHS) announced today that its collective support and services for its Medicare provider partners generated $20 million in total savings through the Next Generation (NextGen) ACO Program in 2021, according to figures released by the Centers for Medicare & Medicaid Services (CMS).


In 2021, CHS managed two NextGen ACOs, the Accountable Care Coalition (ACC) of Southeast Texas and the Accountable Care Coalition (ACC) of Tennessee. Leveraging innovative technology to track population health trends, CHS helped the ACOs improve care and quality outcomes while promoting cost efficiency.


In addition to the $20 million in savings, in 2021 the CHS-backed ACOs:

  • Collectively served more than 39,000 Medicare beneficiaries
  • Achieved a savings rate of 4.7.%
  • Earned $19.81 million in shared savings
  • Scored 97.5% in quality

2021 marks the last year for the NextGen ACO model. The goal during its inception was to test whether Medicare fee-for-service beneficiaries could see better health outcomes and lower expenditures by pairing strong financial incentives with tools for better patient engagement and care management. Under the model, provider groups assumed higher levels of financial risk and reward than are available under the Medicare Shared Savings Program (MSSP). Overall, the model offered an opportunity to set predictable financial targets, provided greater opportunities for providers and beneficiaries to coordinate care and aimed to attain the highest quality standards of care. CHS participated in the model since it started in 2016. ACC of Southeast Texas and ACC of Tennessee collectively saved the Medicare program more than $120M in that time.


“While the model is sunsetting, there are many lessons learned that can be applied to other value-based programs to achieve savings and improve care,” said Anthony Valdés, President of Collaborative Health Systems. “We are proud of the yearly coordination with our provider partners in Tennessee and Texas and the successful savings we were able to achieve throughout the lifespan of the NextGen ACO program. We look forward to successes of future CMMI models.”
