Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ------------------------------------------------------ | | **Snowflake** | `DWV.HOSPITAL_ENROLLMENTS` | | **Databricks** | `cms_dwv.hospital_enrollments` | | **Coverage** | Nov 2022 – May 2026 | | **Rows** | 393,697 (total across all reporting periods) | | **Cadence** | Monthly | | **Update pattern** | Time-partitioned — each file adds one reporting period | | **CMS published** | 2026-05-18 | | **Loaded** | 2026-05-18 | | **Columns** | 39 data + 6 lineage | | **Identifiers** | NPI · CCN · ZIP codes | | **File versions** | 44 | | **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 2026-05-18** — awaiting the next release.
