You Asked: What quarter will CMS use for the re-specified long-stay antipsychotic measure?
We Answered: CMS will use Q3 2025 (July 1–September 30, 2025) as the initial data collection period for the re-specified long-stay antipsychotic medication measure (CMS ID: N047.01), which begins public reporting in January 2026. This information is also noted in CMS’s December 1, 2025 manual update, which details the measure’s re-specification to include Medicare and Medicaid claims and encounter data alongside MDS data.
CMS will update the measure quarterly and provide resident-level results to support facility review. The December update also includes broader changes to the Quality Measures User’s Manual v18.0, including a summary of notable revisions and updated risk-adjustment appendices.
