This week, our In Focus section reviews the Center for Medicare and Medicaid Innova-tion (CMMI) Health Care Innovation Challenge. The CMMI Innovation Challenge initia-tive will award a total of $1 billion in funding through contracts of $1 million to $30 mil-lion to applicants who propose to rapidly implement new models of health care service delivery and payment improvements that meet the “triple aim” of: (1) improved health status for a population, (2) higher quality of the patient experience, and (3) lower costs. These models will organize the care for Medicare, Medicaid, and Children’s Health In-surance Program (CHIP) enrollees.
