Comprehensive Care for Joint Replacement (CJR)

The Comprehensive Care for Joint Replacement (CJR) model is a mandatory bundled payment program for hospitals located in 67 metropolitan statistical areas (MSAs). Hospitals that meet quality and cost thresholds for their Medicare lower-extremity joint replacement patients are eligible to receive savings. Episodes begin with a hospital admission and extend 90 days post-discharge. The risk phase of CJR started on April 1, 2016, and lasts for five years.

The AAMC launched the CJR Collaborative in spring 2016 and currently supports 15 hospitals in implementing the mandated program. The AAMC provides advocacy support, data and policy analyses, project management services, and facilitated learning. Data services are enhanced through the AAMC’s partnership with DataGen and Singletrack Analytics.
