Paul M. Katz has worked with some of the largest Medicare and commercial accountable care organizations in the country, with capitated medical groups and IPAs across California, and health plans throughout the U.S. to improve the quality of their data and the resulting information physicians and management teams rely on to make informed and effective decisions. He was a contributing author of the ACO Learning Network Tool Kit, published by the Brookings Institution, and has presented at major conferences, including the CAPG Annual Conference, where he reported on early comparative results for a Medicare ACO and Medicare Advantage program using the same core provider network.
