# Facility Affiliation Data

Part of the [CMS Data Feeds Dataset](/data-catalog/cms-data-feeds-dataset/cms-data-feeds-catalog.md) › Medicare

Dataplex delivers this CMS feed as the analysis-ready table `DWV.FACILITY_AFFILIATION_DATA` on Snowflake and Databricks — 28 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.

## Row-level lineage

Every row in this table traces to the exact CMS source file that produced it. The `FILE_ID` column joins to the `FEEDS_FILES` catalog table, and `FILE_FEED_ID` joins to the `FEEDS` master table:

```mermaid
erDiagram
    FEEDS ||--o{ FEEDS_FILES : "ID = FEED_ID"
    FEEDS ||--o{ FACILITY_AFFILIATION_DATA : "ID = FILE_FEED_ID"
    FEEDS_FILES ||--o{ FACILITY_AFFILIATION_DATA : "ID = FILE_ID"

    FEEDS {
        text ID PK
        text TITLE
        text VIEW_NAME
        text ACCURAL_PERIODICITY
    }
    FEEDS_FILES {
        text ID PK
        text FEED_ID FK
        date TEMPORAL_START
        date TEMPORAL_END
        date CMS_FEED_MODIFIED
        number IS_LATEST
    }
    FACILITY_AFFILIATION_DATA {
        text ROW_ID PK
        text FILE_ID FK
        text FILE_FEED_ID FK
        number NPI
        number IND_PAC_ID
        text PROVIDER_LAST_NAME
        text PROVIDER_FIRST_NAME
        number remaining_5_data_columns
    }
```

Trace any row back to its source file and reporting period:

```sql
SELECT d.NPI, d.IND_PAC_ID, d.PROVIDER_LAST_NAME,
       ff.TEMPORAL_START, ff.TEMPORAL_END, ff.CMS_FEED_MODIFIED
FROM DWV.FACILITY_AFFILIATION_DATA d
JOIN DWV.FEEDS_FILES ff ON d.FILE_ID = ff.ID;
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dataplex-consulting.com/data-catalog/cms-data-feeds-dataset/cms-data-feeds-catalog/facility-affiliation-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
