Interwell Health, founded in 2019, is a kidney care management company headquartered in Waltham, Massachusetts. It focuses on partnering with physicians, payers, and patients to improve outcomes for people living with kidney disease through value-based care and innovative management strategies. The company was formed by merging three industry leaders in August 2022: Fresenius Health Partners, the legacy InterWell Health network of over 1,600 physician partners, and Cricket Health, which contributes advanced data and analytics capabilities.
In September 2022, Interwell Health expanded its vision in kidney care by acquiring Acumen Physician Solutions, a leading provider of electronic health records and patient management software designed specifically for nephrologists managing chronic kidney disease. The company aims to make kidney care smarter and easier, improving patient outcomes and financial performance for healthcare partners.
Interwell Health manages a national footprint serving over 145,000 patients with a network of more than 2,200 providers, demonstrating strong results such as a 150% greater optimal start rate and an 85% higher home dialysis start rate than the national average. They also report approximately 20% fewer all-cause hospitalizations and significant cost savings of around $500 per member per month in total cost of care.
Built on a physician-driven governance model and decades of experience in value-based care arrangements, Interwell Health fosters collaboration among clinicians nationwide to support renal patient populations across the full continuum of care. Their approach integrates clinical excellence, data analytics, and coordination with payers to deliver sustainable improvements in kidney care.
Overall, Interwell Health represents a leading innovator in kidney care management, positioning itself to redefine treatment paradigms by combining expertise, technology, and compassionate care for better health outcomes and system-wide cost savings.
