News & Insights Reminder: 2020 only a testing year for AUC Washington Connection Federal Compliance Sign in to save January 16, 2020: Some medical group practices have been told to immediately purchase and use Clinical Decision Support Mechanism (CDSM) software to comply with the Appropriate Use Criteria (AUC) program, with vendors suggesting that claims payment would be impacted in 2020. In a posting on its website, the Centers for Medicare & Medicaid Services (CMS) reiterated that 2020 is an educational and operational testing period and there are no payment consequences this year. The AUC program will require ordering professionals to consult CDSM software for certain advanced imaging tests and require rendering professionals to include that consultation code on their Medicare claims starting in 2021. Practices are encouraged, however, to plan for implementation of CDSM software and test workflows at some point this year. Access the MGMA AUC Toolkit for additional information on the program.
