Reportable Condition Mapping Table (RCMT)

The RCMT provides mappings between reportable conditions and their associated LOINC laboratory tests and SNOMED results. The RCMT uses standards suggested for the meaningful use measure “reportable lab result reporting to public health”. In previous incarnations the RCMT was known as the “Dwyer tables”, “Sable tables” or Notifiable Condition Mapping Tables (NCMTs).

Who is coordinating this effort?
  • The Standards Workgroup under the CDC/CSTE Electronic Laboratory Reporting (ELR) Task Force leads the charge to maintain the Reportable Condition Mapping Table.
  • The RCMT process is an ongoing effort that engages a wide range of stakeholders, including subject matter experts in laboratory medicine, epidemiology, infection prevention and informatics (especially vocabulary standards), as well as members of the EHR/LIS vendor community in review and comment of the RCMT.
What is its benefit?
  • Public health organizations: RCMT helps identify incoming Health Level Seven International (HL7) ELR messages that are related to reportable conditions and also facilitates the routing of ELR messages to appropriate public health programs (e.g., tuberculosis and malaria).
  • Laboratories: RCMT facilitates the mapping of local laboratory test and result codes related to reportable conditions to standard vocabulary codes, which also helps to achieve semantic interoperability.
  • Hospitals: The RCMT can be used in electronic health records (EHR) decision support systems to help identify patients who may have reportable conditions, which would trigger public health case reporting and ELR.
  • Laboratory Information System (LIS) Vendors: The information in the RCMT adds value to laboratory information systems by facilitating the implementation of ELR, public health case reporting, and healthcare associated infection reporting.
When was it completed?
  • RCMT content for 109 reportable conditions was published on June 30th, 2011. However, updates will be on-going since laboratory tests and standard codes change over time. Therefore, the RCMT does not have a discrete end point.
How will it be delivered? Where can I get more information?
  • The RCMT public review meetings are done via webinar on a monthly basis, or as needed to maintain the RCMT.
