CMS proposes to increase the required number of quarters of electronic clinical quality measure (eCQM) data reporting from hospitals over a three year period, from one quarter in 2020 to four quarters in 2023. Additionally, CMS proposes requiring hospitals to report the Safe Use of Opioids eCQM as one of the four eCQMs starting in 2022. For the first time in 2021, eCQM performance data will be publicly reported on Hospital Compare. Audits will also merge chart-abstracted and eCQM review into a single audit starting in 2022.
