Long Term Care Minimum Data Set (MDS) - Swing-Bed 3.0

The Long Term Care Minimum Data Set (MDS)-Swing Bed is a health status screening and assessment tool. It is required for Medicare payment of hospital-based skilled nursing care. Swing-bed providers are hospitals that can use their beds, as needed, to provide either acute or post-acute skilled nursing care.  The swing-bed assessment includes a subset of the skilled nursing facility (SNF) assessment items. The MDS 3.0 was implemented in October, 2010, replacing version 2.0.

Special considerations

Background:

CMS has developed a new Medicaid DQ Atlas, an interactive, web-based tool that helps policymakers, analysts, researchers, and other stakeholders explore the quality and usability of the Medicaid TMSIS Analytic File (TAF). The charts, maps, and tables in the new DQ Atlas show state-level DQ assessments and associated measure values for topics that are pertinent to Medicaid and CHIP.

2019 Preliminary Medicaid and CHIP Data Now Available

CMS is pleased to announce the availability of Preliminary Medicaid T-MSIS Analytic Files (TAFs) for calendar year 2019. Beginning with 2019 data, CMS plans to release a “Preliminary” version of the TAF RIF for each service year to give TAF users earlier access to Medicaid data in the research file format. The Preliminary RIF data is not fully mature because states are still submitting service use records for that year, so users should be aware of this when planning their analytics.
