MSSP ACOs Data Tools Overview
The Medicare Shared Savings Program (MSSP) is a CMS program that allows groups of healthcare providers to form Accountable Care Organizations (ACOs) and share in savings generated by delivering higher-quality, lower-cost care to Medicare beneficiaries.
The Tuva Project provides a suite of tools specifically designed for MSSP ACO organizations to access, transform, and analyze their CMS data. This section documents ingestion and connector components, the MSSP connector's projected benchmark and savings models, and legacy dashboard templates.
The published connector chain still resolves to Tuva Core 0.17.2 through the CCLF dependency file. These instructions describe that connector workflow, not a validated Core 1.0 installation. Before adopting 1.0, update the complete dependency graph, migrate its Input Layer mappings, and validate your source with Input Data Quality. Changing a Core version pin alone does not establish connector compatibility.
Components
Claims Analytics Pipeline
These components work together sequentially to load raw CMS data into the Tuva Project and produce MSSP-specific analytics:
| Component | Type | Purpose |
|---|---|---|
| MSSP Pipeline | Python CLI | Downloads MSSP ACO files from the CMS Datahub and loads them into your data warehouse |
| CMS MSSP Connector | dbt project | Transforms remaining MSSP report files (BEUR, BAIP, NCBP, MCQM, EXPU, Shadow Bundles, etc.) into data marts |
| CMS ALR Connector | dbt project | Transforms CMS Assignment List Reports (ALR) into the enrollment format required by the CCLF connector, and creates the attribution input format based on data in the ALRs |
| Medicare CCLF Connector | dbt project | Transforms CMS Comprehensive Claims and Line Feed (CCLF) files into the Tuva Input Layer and combines them with ALR data. The current dependency chain uses legacy Core; a 1.0 migration must validate the full graph. |
| CMS ACO Dashboards | Power BI Dashboard | Legacy Tuva 0.18 dashboard templates. The templates have not been validated against the Tuva 1.0 standalone Semantic Layer. |
Claims Analytics Data Flow
The pipeline components run in the following order:
What CMS Data Is Involved
MSSP ACO organizations receive several types of files from CMS through the Datahub portal:
-
CCLF (Comprehensive Claims and Line Feed) — Medicare Parts A, B, and D claims for assigned beneficiaries, plus beneficiary demographic and MBI cross-reference files. This is the primary claims dataset used for cost and quality analytics.
-
ALR (Assignment List Report) — Quarterly reports identifying which beneficiaries are assigned to your ACO. Contains enrollment flags, voluntary alignment designations, and underserved beneficiary indicators.
-
Other MSSP Reports and Files — Additional reports/files including:
- Beneficiary Advanced Investment Payment Report (BAIP)
- Aggregate Expenditure/Utilization Report (EXPU)
- Beneficiary Expenditure/Utilization Report (BEUR)
- Non-Claims Based Payment (NCBP)
- quality metrics population (MCQM)
- Participants List
- Provider and Supplier List
- Shadow Bundle reports
