Data Updates

Lists the data updates for a scheduled quarterly refresh and as well those that are updated in between refreshes.

Part of the CMS Data Feeds Dataset › Medicare

Dataplex delivers this CMS feed as the analysis-ready table DWV.DATA_UPDATES on Snowflake and Databricks — six snapshot releases spanning 2024–2026, aligned to a single schema, refreshed automatically whenever CMS publishes a new file. Every row carries lineage back to the exact CMS source file that produced it.
