Congress established the Center for Medicare and Medicaid Innovation (CMMI) to design, test, and spread innovative payment and service delivery models that either reduce spending without reducing the quality of care or improve the quality of care without increasing spending. CMMI sought to leverage these models to foster market innovation and accelerate the transformation of payment and care delivery to achieve the Triple Aim of better health, better care, and lower cost. This article provides a perspective on the design and execution of CMMI's five initial models, the resulting outcomes and lessons, and how their core concepts evolved within and spread beyond CMMI. This experience yields three key insights that could inform future efforts by CMMI and public and private payers, including model designs and policy decisions. These insights center on the need for iterative testing and learning guided by market feedback, more realistic time frames to demonstrate impact on cost and quality, and greater integration of models.
