Welcome to the MediCOIN (Medicare COding INtensity) Report, a project of the Brown University School of Public Health Center for Advancing Health Policy Through Research. The objective of this website is to better understand variation in measured coding intensity across Medicare Advantage contracts. We report several validated measures of coding intensity in the Medicare Advantage program to better understand variation that could lead to variable payments in the program. Our goal is to make this data publicly available for researchers and policymakers.
