Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ----------------------------------------------------------------------- | | **Snowflake** | `DWV.ENDSTAGE_RENAL_DISEASE_FACILITY_AGGREGATION_GROUP_PERFORMANCE` | | **Databricks** | `cms_dwv.endstage_renal_disease_facility_aggregation_group_performance` | | **Coverage** | Jul 2021 – Dec 2024 | | **Cadence** | Semiannual | | **Update pattern** | Full-refresh — each file replaces the prior snapshot | | **CMS published** | 2025-12-22 | | **Loaded** | 2025-12-22 | | **Columns** | 31 data + 6 lineage | | **File versions** | 13 | | **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 2025-12-22.

The dataset includes information on Performance Payment Adjustment (PPA), Modality Performance Score (MPS), home dialysis rate, and transplant rate, as well as the individual components of each rate for each model participant ESRD facility aggregation group. > > All ESRD facilities within the same aggregation group share the same performance information. The supplementary aggregation group crosswalk file may be used to map aggregation groups to individual ETC Participant ESRD facilities. > > — *Source: CMS feed metadata* **Keywords:** Medicare, Original Medicare, Hospitals & Facilities, Outpatient Facilities, Clinics, End Stage Renal Disease Facilities, Value-Based Care, Coordinated Care, Service Delivery Models **Theme:** Medicare ## Coverage timeline 2021 🟩 · 2022 🟩 · 2023 🟩 · 2024 🟩 4 of 4 years with snapshot releases — no gaps. ## Release history | Reporting period | CMS published | Loaded | Latest file | | ------------------------- | ------------- | ---------- | ----------- | | Snapshot as of 2025-12-22 | 2025-12-22 | 2025-12-22 | ✓ | | Snapshot as of 2025-07-01 | 2025-07-01 | 2025-10-18 | | | Snapshot as of 2025-06-30 | 2025-06-30 | 2025-06-30 | | | Snapshot as of 2025-06-09 | 2025-06-09 | 2025-06-17 | | | Snapshot as of 2024-08-09 | 2024-08-09 | 2025-06-17 | | | Snapshot as of 2024-02-20 | 2024-02-20 | 2025-06-17 | | | Snapshot as of 2023-11-30 | 2023-11-30 | 2025-06-17 | | | Snapshot as of 2023-11-30 | 2023-11-30 | 2025-06-17 | | | Snapshot as of 2025-06-09 | 2025-06-09 | 2025-06-09 | | | Snapshot as of 2024-08-09 | 2024-08-09 | 2024-08-09 | |

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/end-stage-renal-disease-facility-aggregation-group-performance.md?ask=&goal= ``` `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.
