TAMPA, Fla., and KNOXVILLE, Tenn. (Jan. 19, 2021) – Collaborative Health Systems announced today the Accountable Care Coalition (ACC) of Tennessee, LLC generated $21.2 million in shared savings for performance years 2018 and 2019, according to figures released by the Centers for Medicare & Medicaid Services (CMS).

With a focus on reducing the total cost of care for patients in East Tennessee, ACC of Tennessee was formed in 2018 by Summit Medical Group, a physician-led organization, and Collaborative Health Systems, a subsidiary of Centene Corporation. The coalition participates in the CMS Next Generation Accountable Care Organization (ACO) Model.

In performance year 2019, the ACC of Tennessee, which is in its second year in the Next Generation ACO Model:

  •  Served more than 22,000 Medicare beneficiaries across Tennessee;

  •  Achieved an overall quality score of 99%; and,

  •  Generated $15.9 million in shared savings – a 200% increase from performance year 2018.

“Our continued success in striving for clinical excellence and improving care for Medicare beneficiaries is a reflection of the strong partnership we have with CHS,” said Ed Curtis, Chief Executive Officer of Summit Medical Group. “The Next Generation ACO Model continues to help us lead the way to higher quality, more affordable healthcare, and set the pace nationally as a leader in the movement to value-based care.”

In addition to founding member Summit Medical Group, the ACC of Tennessee includes primary care practice participants and specialty healthcare collaborators across the region, such as Knoxville-based Gastrointestinal Associates, Premier Surgical, Tennessee Eye Care and University Eye Specialists.

“We are proud to report the ACC of Tennessee has generated savings for our providers and the Medicare program for the second consecutive year,” said Dr. Bhavana Vora, Medical Director for the Accountable Care Coalition of Tennessee and a partner in Summit Medical Group. “We remain committed to providing high-quality care and services to our patients and are grateful the CMS program allows us to demonstrate how we can provide increasing value in our local communities.”

The Next Generation ACO Model was designed under the CMS Innovation Center to test whether strong financial incentives for ACOs can improve health outcomes and reduce expenditures for Medicare Fee-For-Service (FFS) beneficiaries. Under the Model, groups of doctors and other healthcare providers come together voluntarily to provide coordinated, high-quality care at lower costs to their Medicare FFS beneficiaries. Provider groups in this Model assume higher levels of financial risk and reward than are available under the Medicare Shared Savings Program (MSSP). The Model engages beneficiaries in their care through benefit enhancements designed to improve the patient experience and rewards seeking appropriate care from providers and suppliers participating in ACOs.

“The ACC of Tennessee continues to demonstrate how physicians committed to efficiency and enhancing patient care can succeed by embracing value-based models that increase accountability, lower costs, and improve quality of care,” said Anthony Valdés, President of Collaborative Health Systems. “We look forward to our continued partnership as we work to achieve quality health outcomes, healthier patient populations, and lower costs in Tennessee communities.”
