What InterWell Health does
InterWell Health is a privately held value-based kidney care company headquartered in Waltham, Massachusetts, operating as the value-based care segment of Fresenius Medical Care. The company was formed in August 2022 through a three-way merger combining Fresenius Health Partners, the InterWell physician network, and Cricket Health, with Acumen Physician Solutions acquired from Fresenius Medical Care North America in September 2022. InterWell serves health plans and payers (Humana, UPMC Health Plan, Providence Health Plan, WVU Medicine, among 15+ contracts), nephrology practices (2,300+ nephrologists across 200+ practices in 38 states), and CKD/ESKD patients (160,000+ lives under management as of 2024, 600,000+ served cumulatively).
The core technology platform is Interwell Acumen, a nephrology-specific electronic health record built on Epic Connect with 25+ years of specialized workflows, integrated with the Acumen Rounder mobile rounding application for nephrologists. The service portfolio includes Interwell 360 (patient engagement and care coordination via interdisciplinary teams), Interwell Learning (reimbursable bilingual kidney disease education platform), Interwell Practice Resources (consulting and group purchasing), Interwell Medical Group (telehealth kidney specialists), and the Interwell Provider Network. The company also operates OakWell, a joint venture with Oak Street Health, delivering primary care in dialysis centers.
InterWell generates revenue primarily through full-risk total-cost-of-care contracts with health plans where shared savings accrue when kidney disease cost benchmarks are beaten; additional streams include quality-based incentive payments, Medicare KDE benefit billing through Interwell Learning, and Acumen EHR subscription services. The company is the largest participant in the CMS Comprehensive Kidney Care Contracting model, having delivered $273M in shared savings to CMS over three years with an 88% average quality score. As of late 2025 / early 2026, leadership comprises CEO Tommy O'Connor (appointed October 2025), President & COO David Pollack, CFO Adriana Day, and CMO Dr. Carney Taylor (appointed January 2026).

Revenue model
- Value-Based Care Contracts with Shared Savings: Interwell Health generates revenue through full-risk total-cost-of-care partnerships with health plans. The company takes on financial risk for kidney disease patient populations, earning shared savings when costs are reduced below benchmarks while maintaining quality outcomes. All program delivery costs are at risk and only recovered if savings are created.
- Quality-Based Incentives: Revenue generated through quality incentive payments tied to performance on kidney disease quality measures and CKCC model benchmarks. Practices can earn quality incentives and access bonus programs.
- KDE Education Billing: Interwell Learning generates revenue through Medicare's KDE (Kidney Disease Education) benefit billing. Practices subscribe to Interwell Learning and bill Medicare directly based on KDE benefit guidelines.
- EHR/Software Services: Revenue from providing Acumen EHR platform to nephrology practices, including support services and software access.

InterWell Health competitors and assessment
Company assessmentBroad incumbents
- DaVita: DaVita is one of the largest US dialysis services providers and operates its own value-based care initiatives (DaVita Integrated Kidney Care). As a broad incumbent, DaVita competes in some kidney care management offerings while primarily serving as a dialysis services partner.
- U.S. Renal Care: U.S. Renal Care operates a national network of outpatient dialysis centers with value-based care initiatives for kidney patients. It competes with Interwell in dialysis-adjacent kidney care management.
- Fresenius Medical Care: Fresenius Medical Care is the parent company of Interwell Health and the largest US dialysis services provider. It operates value-based kidney care programs through Fresenius Health Partners (now part of Interwell), making it both a sponsor and adjacent operator in the same space.
Direct peers
- Somatus: Somatus operates value-based kidney care programs with commercial, Medicare Advantage, and Medicaid payers, deploying interdisciplinary care teams for CKD and ESRD patients. It is one of Interwell's primary competitors for full-risk kidney contracts.
- Strive Health: Strive Health is a direct competitor offering value-based kidney care contracts with payers and kidney care management for CKD/ESRD patients. Both companies compete on shared-savings arrangements, nephrology provider enablement, and predictive analytics targeting the same CKCC contracting landscape.
- Healthmap Solutions: Healthmap Solutions provides value-based kidney care management for health plans, focusing on CKD identification, care coordination, and cost reduction. It is a direct competitor in the payer-facing kidney care management space.
- Monogram Health: Monogram Health is a value-based kidney care company providing in-home nephrology, primary care, and care coordination services to health plan members with chronic kidney disease. It competes head-to-head with Interwell for payer contracts covering CKD/ESRD populations.
Emerging players
- Renalogic: Renalogic offers value-based kidney care management and cost-containment services for self-funded employers and payers. It is a niche emerging player focused on dialysis cost containment, partially overlapping with Interwell's payer-focused offerings.
Others
- Epic Systems: Epic is the underlying EHR platform on which Interwell Acumen is built (Epic Connect). While not a direct competitor, Epic enables Interwell's technology stack and represents both an integration partner and a potential competitor if Epic expands vertically into nephrology-specific modules.
Regional players
- National Renal Alliance: National Renal Alliance is a regional dialysis services and kidney care provider with partnerships across multiple states. It overlaps with Interwell in nephrology provider enablement but operates on a more regional scale.
