Dataset: Master Beneficiary Summary File (MBSF) Cost & Use Segment (CUS) (MBSF-CUS)
| Basic Information | |
|---|---|
| Dataset Full Name | Master Beneficiary Summary File (MBSF) Cost & Use Segment (CUS) |
| Dataset Acronym | MBSF-CUS |
| Summary | The Cost & Use Segment (CUS) is one of five segments available in the Chronic Conditions Data Warehouse (CCW) Master Beneficiary Summary File (MBSF). The Cost and Use segment includes summaries of Medicare payment amounts and services utilization. The CUS is a segment of the Chronic Conditions Data Warehouse (CCW) Master Beneficiary Summary File (MBSF), a research database created by the Center for Medicare and Medicaid Services (CMS) following passage of the Medicare Modernization Act of 2003. CCW data contains CMS administrative data that spans multiple care settings starting in 1999, tied together with a unique beneficiary key allowing linkages of an individual's data across data types and sources. It contains 100% Medicare files (1999-present), 100% Medicaid files (1999-present) as well as 100% of Part D Prescription Drug Event data (1999-present). The design of the CCW linked data allows researchers to analyze information across the continuum of care across multiple care settings. The purpose of the CCW is to help researchers identify and improve the quality of healthcare for chronically ill Medicare beneficiaries. The Master Beneficiary Summary File (MBSF) is made up of five segments. CCW data are available upon request for a random 5% sample, for specific chronic condition cohorts or an investigator-defined sample. The other data segments available in the Master Beneficiary Summary File can be requested and linked to the Cost and Use segment data:
