Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ----------------------------------------------------- | | **Snowflake** | `DWV.VALUE_MODIFIER` | | **Databricks** | `cms_dwv.value_modifier` | | **Coverage** | Jan 2013 – Dec 2016 (4 of 4 annual reporting periods) | | **Rows** | 637,957 (total across all reporting periods) | | **Cadence** | Annual | | **Update pattern** | Time-partitioned — each file adds one reporting year | | **CMS published** | 2025-09-11 | | **Loaded** | 2025-10-18 | | **Columns** | 13 data + 6 lineage | | **File versions** | 5 | | **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 2025-09-11. Coverage is complete through the 2016 reporting year. Next CMS release expected \~Sep 2026. {% endhint %} {% hint style="info" %} **Time-partitioned feed** — each file version covers one reporting year, so history is additive. Query the full table for all years; filter on the reporting period columns for a single period. Do **not** filter to the latest file only — that would return just the 2016 reporting year. {% endhint %} ## Sample queries {% tabs %} {% tab title="Snowflake" %} ```sql -- Each file version covers one reporting period (2013, 2014, 2015, 2016) — history is additive SELECT * FROM DWV.VALUE_MODIFIER LIMIT 100; ``` {% endtab %} {% tab title="Databricks" %} ```sql -- Each file version covers one reporting period (2013, 2014, 2015, 2016) — history is additive SELECT * FROM cms_dwv.value_modifier LIMIT 100; ``` {% endtab %} {% endtabs %} ## About this feed > The Medicare Value-Based Payment Modifier (Value Modifier) data contains the performance results of de-identified practices that were subject to the Value Modifier, such as the practices' quality and cost tiers along with any applicable Value Modifier payment adjustment. The Value Modifier provided for differential payment under the Medicare Physician Fee Schedule based on the quality of care furnished to Medicare beneficiaries compared to the cost of care during a performance period. Calendar Year 2015 was the first payment adjustment period under the Value Modifier based on performance in 2013. Calendar Year 2018 was the final payment adjustment period under the Value Modifier based on performance in 2016. > > — *Source: CMS feed metadata* **Keywords:** Medicare, Original Medicare, Value-Based Care, Payment Models **Theme:** Medicare ## Coverage timeline 2013 🟩 · 2014 🟩 · 2015 🟩 · 2016 🟩 4 of 4 annual reporting periods present — no gaps. ## Release history | Reporting period | CMS published | Loaded | Latest file | | ----------------------- | ------------- | ---------- | ----------- | | 2016-01-01 – 2016-12-31 | 2025-09-11 | 2025-10-18 | ✓ | | 2016-01-01 – 2016-12-31 | 2021-01-06 | 2023-08-29 | | | 2015-01-01 – 2015-12-31 | 2022-08-04 | 2023-08-29 | | | 2014-01-01 – 2014-12-31 | 2022-08-04 | 2023-08-29 | | | 2013-01-01 – 2013-12-31 | 2022-08-04 | 2023-08-29 | | ## Data dictionary

## 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{ VALUE_MODIFIER : "ID = FILE_FEED_ID" FEEDS_FILES ||--o{ VALUE_MODIFIER : "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 } VALUE_MODIFIER { text ROW_ID PK text FILE_ID FK text FILE_FEED_ID FK number PRACTICE_ID text STATE text NUM_EPS_VM number MSSP number remaining_9_data_columns } ``` Trace any row back to its source file and reporting period: ```sql SELECT d.PRACTICE_ID, d.STATE, d.NUM_EPS_VM, ff.TEMPORAL_START, ff.TEMPORAL_END, ff.CMS_FEED_MODIFIED FROM DWV.VALUE_MODIFIER 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/value-modifier-data-dictionary) * [2018 Value Modifier Performance Year 2016 Methodology](https://data.cms.gov/resources/2018-value-modifier-performance-year-2016-methodology) ## Frequently asked questions ### How often is Value Modifier updated? Annually. CMS last published this feed on 2025-09-11, and Dataplex loaded it to the warehouse on 2025-10-18. New releases are added automatically when CMS publishes them. ### What years does Value Modifier cover? 2013 through 2016 — four annual reporting periods with no gaps. Each reporting year arrives as its own file version, and all years remain queryable side by side. ### How many records are in Value Modifier? 637,957 rows across all five reporting periods. Because this feed is time-partitioned, the full table total is the meaningful count — no deduplication needed. ### How do I get Value Modifier data? It's included in the CMS Data Feeds Dataset on the [Snowflake Marketplace](https://app.snowflake.com/marketplace/listing/GZT1Z125KDH/dataplex-consulting-data-products-cms-data-feeds-dataset) (free trial available) and via [Databricks Delta Sharing](https://checkout.dataplex-consulting.com/b/3cIdR2e1J59Sh2w7pWbQY00).
