Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | -------------------------------------------------------------------- | | **Snowflake** | `DWV.MARKET_SATURATION__UTILIZATION_COREBASED_STATISTICAL_AREAS` | | **Databricks** | `cms_dwv.market_saturation__utilization_corebased_statistical_areas` | | **Coverage** | Oct 2022 – Dec 2025 (4 of 4 annual reporting periods) | | **Rows** | 1,438,963 (total across all reporting periods) | | **Cadence** | Annual | | **Update pattern** | Time-partitioned — each file adds one reporting year | | **CMS published** | 2026-06-10 | | **Loaded** | 2026-06-11 | | **Columns** | 45 data + 6 lineage | | **File versions** | 8 | | **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="success" %} **Current** — CMS last published this feed on 2026-06-10.

CBSAs are geographical delineations that are Census Bureau-defined urban clusters of at least 10,000 people. Market saturation, in the present context, refers to the density of providers of a particular service within a defined geographic area relative to the number of beneficiaries receiving that service in the area. The data can be used to reveal the degree to which use of a service is related to the number of providers servicing a geographic region. There are also a number of secondary research uses for these data, but one objective of making these data public is to assist health care providers in making informed decisions about their service locations and the beneficiary population they serve. > > — *Source: CMS feed metadata* **Keywords:** States & Territories, Rural-Urban, Medicare, Original Medicare, Health Care Use & Payments, Fraud, Waste, & Abuse Prevention **Theme:** Medicare ## Coverage timeline 2022 🟩 · 2023 🟩 · 2024 🟩 · 2025 🟩 4 of 4 annual reporting periods present — no gaps. ## Release history | Reporting period | CMS published | Loaded | Latest file | | ----------------------- | ------------- | ---------- | ----------- | | 2025-01-01 – 2025-12-31 | 2026-06-10 | 2026-06-11 | ✓ | | 2024-01-01 – 2024-12-31 | 2026-02-19 | 2026-02-19 | | | 2024-01-01 – 2024-12-31 | 2025-09-15 | 2025-10-18 | | | 2024-01-01 – 2024-12-31 | 2025-05-21 | 2025-05-21 | | | 2023-01-01 – 2023-12-31 | 2024-10-31 | 2024-11-01 | | | 2023-10-01 – 2023-12-31 | 2024-04-02 | 2024-04-02 | | | 2023-04-01 – 2023-06-30 | 2023-11-08 | 2023-11-08 | | | 2022-10-01 – 2022-12-31 | 2023-04-28 | 2023-08-29 | | ## Data dictionary
