Attributed Medicare fee-for-service beneficiaries in 2016.

c

Includes patient-centered medical home (PCMH) recognition, MAPCP, or CPC Classic. A practice was considered to have PCMH recognition if ≥1 of its PCPs had recognition at some point in 2014-2017 by the Accreditation Association for Ambulatory Health Care, The Joint Commission, the National Committee for Quality Assurance, or the Utilization Review Accreditation Commission. A practice was considered to be an MAPCP participant if it participated in any year during 2011-2014, as determined by a file from CMS. Participants include practices that stayed enrolled in CPC Classic for at least the first 5 months.
