While we work to restore the site, key resources are available here.
Annual Updates to eCQM Specifications
Each year, the Centers for Medicare & Medicaid Services (CMS) updates the electronic clinical quality measures (eCQMs) for potential use in CMS quality reporting programs. CMS updates the specifications annually to align with current clinical guidelines and code systems so they remain relevant and actionable within the clinical care setting. CMS requires the use of the most current version of the eCQMs as specified and intended for the applicable reporting/performance periods for all quality reporting programs.
