This guide references the following code systems.

Name	Definition
cdcNHSN	CDC - National Healthcare Safety Network (NHSN) code system - A set of patient safety and healthcare personnel safety vocabulary concepts and associated identifiers maintained as a code system by the CDC's National Healthcare Safety Network.
HSLOC (HealthcareServiceLocation)	A comprehensive classification of locations and settings where healthcare services are provided. This value set is based on the National Healthcare Safety Network (NHSN) location code system that has been developed over a number of years through CDC's interaction with a variety of healthcare facilities and is intended to serve a variety of reporting needs where coding of healthcare service locations is required. The HSLOC content, including relationships can be accessesd at the following location:
LOINC	LOINC (Logical Observation Identifiers Names and Codes) was developed to provide a definitive standard for identifying clinical information in electronic reports. The LOINC database provides a set of universal names and ID codes for identifying laboratory and clinical test results in the context of existing HL7, ASTM E1238, and CEN TC251 observation report messages. One of the main goals of LOINC is to facilitate the exchange and pooling of results for clinical care, outcomes management, and research. LOINC codes are intended to identify the test result or clinical observation. Other fields in the message can transmit the identity of the source laboratory and special details about the sample.
SNOMED CT	SNOMED CT is owned, maintained and distributed by IHTSDO. IHTSDO is an international organization with countries as members. IHTSDO publishes the international release of SNOMED CT (which is used in FHIR international standards and resources). Each of the IHTSDO member countries may also distribute their own SNOMED CT edition, which contains the international release plus local extension content and derivatives.
