Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ------------------------------------------------------------ | | **Snowflake** | `DWV.AMBULATORY_SURGICAL_CENTER_QUALITY_MEASURES__STATE` | | **Databricks** | `cms_dwv.ambulatory_surgical_center_quality_measures__state` | | **Update pattern** | Full-refresh — each file replaces the prior snapshot | | **CMS published** | 2025-12-16 | | **Loaded** | 2026-02-28 | | **Columns** | 52 data + 6 lineage | | **File versions** | 5 | | **License** | CMS public data — U.S. Government work | | **Platforms** | Snowflake Marketplace · Databricks Delta Sharing | Included in the CMS Data Feeds Dataset — [start a free trial on Snowflake Marketplace](https://app.snowflake.com/marketplace/listing/GZT1Z125KDH/dataplex-consulting-data-products-cms-data-feeds-dataset). {% hint style="info" %} **Last CMS publication 2025-12-16** — awaiting the next release.
