The Health Care Service: Data Reporting Guide (HCSDRG), an ASC X12 specification based on the HIPAA adopted Health Care Claim: Institutional (837), supports state and federal public health reporting requirements. The source of the data content is from the ASC X12 standards, UB-04, the National Committee on Vital and Health Statistics core data set, as well as some state specific public health reporting requirements. The Gap Assist tool, jointly developed with Washington Publishing Company, with support from the Centers for Disease Control and Prevention/National Center for Health Statistics, provides a metadata perspective on the format and content attributes of each data element supported by the HCSDRG. The Gap Assist tool also provides a view across multiple versions of the ASC X12 standards and a map to the various standards previously named.
To assist in the understanding of how ASC X12 messaging works for this public health reporting function, the following mini-X12 tutorial is provided.
The structure of an ASC X12 transaction is designed to minimize reporting redundancies. A case in point is the reporting of the patient information. If the patient is also the health insurance subscriber that patient information is reported where the subscriber information is reported and no where else. If the patient is not the subscriber there is another location in this ASC X12 specification for that patient information to be entered.
For simplicity the Gap Assist tool only points to the place where the Patient Information would be reported if the patient was not the subscriber. Further explanations of this are available by purchasing the Health Care Service: Data Reporting guide from ASC X12: http://store.x12.org.
A recent change also provides a link from the data elements supported in the HCSDRG and an additional set of metadata for each data element contained in the United States Health Information Knowledgebase (USHIK). This includes a data element definition, as well as other information about each data element, such as field length and data type. The USHIK is an on-line, publicly accessible registry and repository of healthcare-related data, metadata and standards. USHIK is funded and directed by the Agency for Healthcare Research and Quality (AHRQ) with management support in partnership with the Centers for Medicare & Medicaid Services (CMS).
