- Interwell achieved top quality scores and sustained savings growth over the first three years of the Kidney Care Choices Model
Bad Homburg (June 10, 2026) - Interwell Health, the value-based care operating segment of Fresenius Medical Care, has released new results showcasing exceptional performance in the U.S. Center for Medicare & Medicaid Innovation’s (CMMI) Kidney Care Choices (KCC) Model1. As the largest participant in the Comprehensive Kidney Care Contracting (CKCC) program option, Interwell delivered $273 million in shared savings2 to the government program and consistently achieved top quality scores (88% average, 9 points higher than non-Interwell CKCC participants) over the first three years of the program, solidifying its leadership in value-based kidney care.
The Centers for Medicare & Medicaid Services (CMS) recently released new data that highlights Interwell’s strong results in the CKCC program:
- Industry-leading quality: Largest share of high performer pool (44% of three-year total), with the most high performers and most perfect scores in 2024
- Outstanding financial results: 43% higher three-year average adjusted gross savings rate compared to non-Interwell Kidney Care Entities (KCEs)
- Scalable growth: Increased gross savings 1 percentage point year over year while serving the largest patient population (in 2024, Interwell served 59,520 patients across 23 KCEs)
“Our leadership in the CKCC program further validates that Interwell Health is setting the standard for kidney care,” said Tommy O’Connor, CEO of Interwell Health. “Our consistent quality results and ability to improve patient outcomes at scale demonstrate that value-based care transforms lives and delivers significant savings to the healthcare system. When you combine a compassionate network of patient-centered nephrologists with Interwell’s hands-on care model and advanced technology, patients win.
Year-over-year improvement and industry leadership
CMMI developed the KCC Model to test strategies that increase care coordination for Medicare patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) while improving outcomes and reducing total cost of care. Since the program’s inception, Interwell has consistently delivered measurable improvements in quality metrics including:
- Higher rates of optimal dialysis starts, which measures the percent of patients who transition from late-stage CKD to ESRD care by starting dialysis at home, starting dialysis in-center with permanent dialysis access, or receiving a preemptive kidney transplant
- Improved Patient Activation Measure (PAM) scores, which measure a patient’s knowledge and confidence in managing their health
- Increased use of home-based therapies, which measures the percent of patients who start dialysis at home instead of in-center
Additionally, Interwell grew its gross shared savings rate 71% over three years (3.6% in 2024 from 2.1% in 2022), reflecting the growing financial success of the CKCC Model as it matures.
Interwell supports nephrology practices in the CKCC with resources including embedded renal care coordinators (RCCs), clinical documentation support, and advanced analytics. “Without an RCC I don't know how this program would work, because the RCCs do so much in terms of increasing optimal starts and engaging family members,” said Dr. William McElhaugh, a nephrologist at Kidney Care Specialists. “We also use Acumen®, Interwell's electronic health record system, which allows us to see patients' medical histories to ensure that they are risk stratified properly, which you need to do to be successful in a value-based program." Kidney Care Specialists is part of the Interwell Philadelphia KCE, one of only five KCEs to earn a perfect score in the 2024 program year.
Interwell’s ongoing success in value-based kidney care is powered by its robust network of more than 2,300 nephrologist partners, comprehensive care model, proprietary Epic® Connect EHR platform Interwell Acumen™, and tight alignment with Fresenius Medical Care. Together, these capabilities enable a sustainable approach to kidney disease management that reduces costs and improves outcomes across the care continuum.
