The Traditional Merit-based Incentive Payment System (MIPS) framework is utilized for collecting and reporting data to MIPS. This includes the Improvement Activity MIPS performance category. The Improvement Activities measure participation in activities that improve clinical practice.

Improvement activities have a minimum of a continuous 90-day performance period (during calendar year (CY) 2022) unless otherwise stated in the activity description. The final 90-day continuous performance period to perform improvement activities begins October 3, 2022. If you haven’t already started performing your improvement activities, you must do so by no later than October 3.
