1 Term no longer in use for MIPS: CMS replaced “advancing care information” with “promoting interoperability;” “clinical practice improvement activities” are now generally known as “improvement activiites;” the EHR “meaningful use” program evolved into the “promoting interoperability” performance category; and the “Physician Quality Reporting System” evolved into the quality performance category.
2 The Common Clinical Data Set is used in 2015-edition CEHRT; the US Core Data for Interoperability is used in 2015-edition Cures Update CEHRT.
3 The HARP system involves a CMS secure identity management portal that provides you with a user ID and password for several CMS applications.
