A data catalog is a collection of metadata, combined with data management and search tools, that helps analysts and other data users to find the data that they need, serves as an inventory of available data, and provides information to evaluate the fitness of data for intended uses.
This page provides the current schemas available in the CDR. All data will more closely reflect the source system. A roadmap for future schemas is available here: Data Roadmap. Refer to User Guides & References for an overview and a guide to the data catalog.
You may need to download documents to see the content if they do not display well.

If you have any technical questions regarding the information on this page or the CCSQ Data & Analytics Modernization effort overall, please send an email to servicecentersos@cms.hhs.gov, routing to ADO-QualityNet Analytics-Support.
All data listed below is currently in the CDR; however, a user will only see what is defined by their DUA.
The data refresh dates from CDR sources are published for awareness of data timeliness. If your organization requires data to be refreshed on a different timeline or cycle, please submit a Request Form and include details of your request including business justification, data source, requested refresh frequency, and requested refresh dates.
Details of the refresh are included in the description of each source. The "Next Refresh" date marks the last possible day the data will be available in the CDR.
Please note that due to ongoing modernization efforts, this document is a work in progress. Additional information will be added regularly. Some dates may change due to changing requirements or security mandates.

CSAT
The Healthcare Quality Analytics and Reporting (HCQAR) Complete Statistical Analysis Table (CSAT) is a monthly dataset that provides state and national level claims data variables derived from Medicare Part A / Part B / Part D claims data specifically for the national and state Quality Improvement Networks and Organizations (QIN-QIOs). (SORN)
The source data for Part D claims is the Drug Data Processing System. Each monthly refresh generally includes all drug claims processed from the previous month (as shown by 'pde_proc_dt'). This schema contains all prescription drug claims covered under Medicare Part D. (SORN)
Monthly - By the 12th of each month or the following business day
Yes
NCH Part A
The source data for Part A claims is the National Claims History (NCH) weekly extracts. Each weekly refresh generally includes claims with an ‘nch_daily_proc_dt’ of Friday from the previous week. Part A claims include the Inpatient (IP) and Skilled Nursing Facility (SNF), Home Health (HHA), Hospice, and Outpatient extracts. (SORN)
The source data for Part B claims is the NCH weekly extracts. Each weekly refresh generally includes claims with an ‘nch_daily_proc_dt’ of Friday from the previous week. Part B claims include the Professional and the Durable Medical Equipment (DME) extracts. (SORN)

Important Notes
The CDR follows NCH logic, as such Part A claims are split into multiple records when the number of revenue center line items is greater than 45. In HAJI, these were merged into a single claim.
The CDR includes claim types 61, 62, 63, 64, 80, and 81, which HAJI did not include.
The CDR includes claim adjustments older than five years, which HAJI did not include.
In Part A Claims, dates showing as '1970-01-01' in the rev_cntr_dt field should be treated as blank or null values
