Evaluation of Economic and Clinical Outcomes Under CMS' Mandatory Bundled Payments for Joint Replacements

In the first 2 years, 90-day Medicare Part A spending decreased significantly by $582 per episode (−2.5%) associated with the Comprehensive Care for Joint Replacement model, driven by a 5.5% decrease in postacute spending. No detectable changes in hospital length of stay, readmissions, complications, 30- or 90-day mortality, volume of episodes, or patient characteristics relative to control were found.
