US Core Implementation Guide
10.0.0-ballot - STU 10 Ballot
US Core Implementation Guide, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 10.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/US-Core/ and changes regularly. See the Directory of published versions
| Page standards status: Trial-use |
This page lists all the ValueSets, CodeSystems, and ConceptMaps defined as part of the US Core Implementation Guide. For more information on using codes in US Core, see the FHIR Terminology section in the FHIR specification and the Coded Elements section in this guide.
Terminology is central to US Core. Code systems and value sets change over time, independent of or due to the US Core's annual updates. These changes include adding, deprecating, or retiring code, as well as updating code definitions. In large code systems or value sets, these changes may go unnoticed; however, for smaller enumerated terminologies, they can be obvious and lead to breaking changes.
Every published version of US Core also publishes a snapshot of the latest versions of code systems and value sets, along with their expansions, at the time of publication. This snapshot of these versions can be viewed in the Expansion Parameters resource. However, US Core does not require a specific version of terminology to be used with a specific version of US Core. For example, in US Core version 6.1.0, the US Core Laboratory Test Codes link to version 6.1.0 of the ValueSet. However, its canonical URI, http://hl7.org/fhir/us/core/ValueSet/us-core-laboratory-test-codes, resolves to the latest published version of the valueset; in other words, it links to this more recent version of US Core's valueset. This flexibility better reflects real-world use of US Core. When implementing US Core, implementers SHOULD use the published versions or later versions of the value sets and code systems.§ In some cases, implementers MAY need to use terminology from earlier versions to preserve legacy data.§
In addition to the terminology published with each version of US Core, the link below provides annual value set package updates for US Core Versions 6.1.0, 8.0.1, and 9.0.0 to assist implementers who require them. These packages contain all the expanded value sets required for an implementation guide, and are based on the current code system and value set versions.
Most value sets used in this guide are defined in the base FHIR specification, HL7 Terminology (THO), or the Value Set Authority Center (VSAC). However, US Core also defines several value sets and they are listed below.
Value sets in US Core and C-CDA may retain inactive codes. These codes may be useful for historical queries but are not recommended for new data. Implementers should note that some code systems exclude inactive codes from current expansions; if needed, these codes may be accessible through prior expansions via terminology services. HL7 recommends validators allow non-active codes with note on their status.
The following table lists all the Value sets used in US Core and where they can be found. This information is also available as a csv or excel file.

See the FHIR terminology section for a complete discussion on code systems and a list of code system names used in FHIR. Most code systems used in this guide are defined in the base FHIR specification or HL7 Terminology (THO). However, the following code systems are unique to this guide and not listed in the base FHIR specification. If a URI is listed here, it SHALL be used in the US Core profiles to identify the code system in preference to any other code system URI.
The following table lists all the CodeSystems used in US Core and where they can be found. This information is also available as a csv or excel file.

| 75 | Logical Observation Identifiers | http://loinc.org |
LOINC provides a set of universal names and ID codes for identifying laboratory and clinical test results.1 2 LOINC facilitates the exchange and pooling of results such as blood hemoglobin serum potassium or vital signs for clinical care outcomes management and research. LOINC's universal identifiers (names and codes) can be used in the context of order and observation exchanges between information systems that use syntax standards such as HL73 CEN TC251 ISO TC215 ASTM4 and DICOM. Specifically the identifier can be used as the coded value for an observation in any other standard that uses the observation/observation value paradigm whether messages documents application programming interface (API) etc. For example LOINC codes are used widely in the OBX segment Observation Identifier field (OBX-3) of an ORU HL7 (HL7 version 2.x or ASTM 1238-9410) message that may be sent between a Clinical Laboratory Information Management Systems (LIMS) and Electronic Health Record Systems (EHR).5 6 In this way LOINC codes provide universal identifiers that allow the exchange of clinical data between heterogeneous computing environments. |

This guide links terminology directly to the FHIR® Terminology Service for VSAC Resources (Value Set Authority Center (VSAC)), where applicable, using a RESTful API service to access the VSAC value sets and supported code systems. See the table above for a list of value sets used in US Core that VSAC defines.
To view the value set expansion in the VSAC user interface, use:
GET https://vsac.nlm.nih.gov/ValueSet/[VSAC OID]/expansion
An example of this is shown in the screenshots below.
When viewing a ValueSet in the VSAC UI, the Code System OIDs and VSAC Code System names are displayed for each code. However, these code system identifiers SHOULD NOT be used. The FHIR URIs code systems are defined as part of FHIR and SHOULD be used instead. Unfortunately, the FHIR URI for the code system is not shown. As a convenience for the reader, a VSAC to FHIR Code System Mapping Table is provided, which maps the VSAC Code System names to the corresponding FHIR URI. For more information, see this documentation describing the relationships between the VSAC value set name, FHIR value set name, and FHIR value set title and how to access VSAC's FHIR API.
To fetch the FHIR ValueSet resource (in other words, the value set definition), use:
GET https://cts.nlm.nih.gov/fhir/ValueSet/[VSAC OID]
To fetch the FHIR ValueSet resource expansion, use the FHIR $expand operation:
GET https://cts.nlm.nih.gov/fhir/ValueSet/[VSAC OID]/$expand
For more information, refer to the FHIR Terminology Service for VSAC Resources
For example, the US Core Tobacco And Nicotine Use Observation Profile valueCodeableConcept element has a preferred binding to the Smoking Status value set. To access it in VSAC, click on the link to https://vsac.nlm.nih.gov/valueset/2.16.840.1.113883.11.20.9.38/expansion:
The reader is redirected to the VSAC login page to enter an API Key (only one login is required per session):
After successfully entering the API Key, the value set can be inspected, downloaded, etc., using the VSAC User interface, as shown in the figure below. This FHIR ValueSet resource can also be fetched using the URL https://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113883.11.20.9.38, and the FHIR ValueSet expansion using the URL https://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113883.11.20.9.38/$expand.
