Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ------------------------------------------------------- | | **Snowflake** | `DWV.SPECIFIC_CHRONIC_CONDITIONS` | | **Databricks** | `cms_dwv.specific_chronic_conditions` | | **Coverage** | Jan 2007 – Dec 2018 (12 of 12 annual reporting periods) | | **Rows** | 2,833,488 (total across all reporting periods) | | **Cadence** | Annual | | **Update pattern** | Time-partitioned — each file adds one reporting year | | **CMS published** | 2022-01-10 | | **Loaded** | 2023-08-29 | | **Columns** | 12 data + 6 lineage | | **File versions** | 12 | | **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 2022-01-10** — awaiting the next release.

## Data dictionary
📋 12 data columns + 6 lineage columns Column-level definitions are maintained by CMS in the official [Specific Chronic Conditions data dictionary](https://data.cms.gov/resources/specific-chronic-conditions-data-dictionary). **Data columns** | Column | Type | | -------------------------- | ------ | | `BENE_GEO_LVL` | TEXT | | `BENE_GEO_DESC` | TEXT | | `BENE_GEO_CD` | NUMBER | | `BENE_AGE_LVL` | TEXT | | `BENE_DEMO_LVL` | TEXT | | `BENE_DEMO_DESC` | TEXT | | `BENE_COND` | TEXT | | `PRVLNC` | NUMBER | | `TOT_MDCR_STDZD_PYMT_PC` | NUMBER | | `TOT_MDCR_PYMT_PC` | NUMBER | | `HOSP_READMSN_RATE` | NUMBER | | `ER_VISITS_PER_1000_BENES` | NUMBER | **Lineage columns** (present on every feed table) | Column | Type | Description | | -------------- | -------------- | -------------------------------------------- | | `ROW_ID` | TEXT | Unique row ID for this table (PK) | | `FILE_ID` | TEXT | Source file — joins to `FEEDS_FILES.ID` (FK) | | `FILE_FEED_ID` | TEXT | Parent feed — joins to `FEEDS.ID` (FK) | | `FILE_NAME` | TEXT | Source file name as published by CMS | | `ROWNUM` | NUMBER | Row number within the source file | | `CREATED_AT` | TIMESTAMP\_NTZ | Timestamp when the record was loaded |
## 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{ SPECIFIC_CHRONIC_CONDITIONS : "ID = FILE_FEED_ID" FEEDS_FILES ||--o{ SPECIFIC_CHRONIC_CONDITIONS : "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 } SPECIFIC_CHRONIC_CONDITIONS { text ROW_ID PK text FILE_ID FK text FILE_FEED_ID FK text BENE_GEO_LVL text BENE_GEO_DESC number BENE_GEO_CD text BENE_AGE_LVL number remaining_8_data_columns } ``` Trace any row back to its source file and reporting period: ```sql SELECT d.BENE_GEO_LVL, d.BENE_GEO_DESC, d.BENE_GEO_CD, ff.TEMPORAL_START, ff.TEMPORAL_END, ff.CMS_FEED_MODIFIED FROM DWV.SPECIFIC_CHRONIC_CONDITIONS d JOIN DWV.FEEDS_FILES ff ON d.FILE_ID = ff.ID; ``` ## Source & provenance Published by the **Centers for Medicare & Medicaid Services** (bureau 009:38). * [Official CMS data dictionary](https://data.cms.gov/resources/specific-chronic-conditions-data-dictionary) * [Medicare Chronic Conditions Methodology](https://data.cms.gov/resources/medicare-chronic-conditions-methodology) ## Frequently asked questions ### How often is Specific Chronic Conditions updated?
