health management solutions.

We engage as an operating partner to provide the people, processes and enabling technology essential for payers and health systems to deliver Population Health Services Organization capabilities. The depth and breadth of our solutions—combined with our decade of experience in value-based care—make Lumeris an ideal partner for any health care organization seeking to transform its business and care-delivery model and remarkably improve its clinical and financial outcomes.


Our History

A decade ago, a team of health care executives who had grown frustrated with the nation’s dysfunctional health care system asked themselves a question:

What are the most pressing issues in health care, and how do we fix them?

In the current system, it seemed that for someone to win, someone else always had to lose. For the health care system to thrive, the classic adversarial relationship among payers and providers had to end. After much deliberation, these executives distilled their solution to a single word: share. They believed we needed to relearn this childhood lesson and apply it to our broken health care system. This called for an innovative approach, with economics and data shared freely across the continuum of care. It meant incentives—not punishments—offered to encourage optimal behaviors, then supported with the right information and tools.

Our History

These executives set out to fulfill their mission with the generous assistance of many who believed positive, disruptive innovations can change the world. They established the first collaborative payer, Essence Healthcare. Under this model, Essence did not own the continuum of care but instead worked collaboratively with providers in a virtual integrated delivery system. It established new value-based reimbursement models to align incentives, affording providers the time to more proactively manage and coordinate patient care. It developed cloud-based technology to deliver actionable clinical and financial data to providers, along with the tools to leverage that information.

The task was not always easy, but from growing pains came promise. The results were nothing short of remarkable. Costs dropped. Quality improved. Patient satisfaction increased, and provider engagement grew. Through sharing, Essence had united the continuum of care in a common purpose: Ensuring every patient receives the right care in the right setting and at the right cost, with clear accountability for clinical and financial outcomes.

Today, with the nation’s health care industry still struggling and the concept of value-based accountability on the rise, Lumeris shares these transformative technologies, programs, and methods with health plans, hospitals, and other organizations seeking to establish their own high-performing accountable delivery systems.
