2. When do I begin participating? The fourth QPP performance year began on January 1, 2020 and ends on December 31, 2020. CMS no longer offers the “test” and “partial” participation options that were available as part of the 2017 transition year policies. In 2020, the performance period for the quality and cost categories is 12 months (January 1 – December 31, 2020) and the performance period for the PI and improvement activities categories is a minimum of a continuous 90-day period within the 2020 calendar year.
