NHSN Terminology

HSLOC and CDCNHSN are code systems maintained by NHSN.  For background on how NHSN uses HSLOC, see Chapter 15: CDC Location Labels and Location Descriptions pdf icon[PDF – 1 MB] of the Patient Safety Component Manual. The CDCNHSN code system is highly specialized to meet the needs of NHSN surveillance reporting, is undergoing changes, and is not recommended for creating value sets to be used outside of NHSN.
