Summary
| Defining URL: | http://hl7.org/fhir/ValueSet/focal-subject | 
| Name: | Focal Subject Codes | 
| Definition: | Example VS composed from SNOMED CT and HL7 v3 codes for observation targets: donor, fetus, spouse. As use cases are discovered more values may be added. | 
| OID: | 2.16.840.1.113883.4.642.2.400 (for OID based terminology systems) | 
| Copyright: | This value set includes content from SNOMED CT, which is copyright © 2002+ International Health Terminology Standards Development Organisation (IHTSDO), and distributed by agreement between IHTSDO and HL7. Implementer use of SNOMED CT is not covered by this agreement. | 
| Source Resource | XML / JSON | 
This value set is used in the following places:

This value set includes codes from the following code systems:
| Code | Display | |
| 83418008 | Fetus | 
| Code | Display | |
| DON | donor | In some organ transplantation services and rarely in transfusion services a donor will be a target participant in the service. However, in most cases transplantation is decomposed in three services: explantation, transport, and implantation. The identity of the donor (recipient) is often irrelevant for the explantation (implantation) service. | 
| Code | Display | |
| SPS | spouse | The player of the role is a marriage partner of the scoping person. |

Explanation of the columns that may appear on this page:
| Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies | 
| Source | The source of the definition of the code (when the value set draws in codes defined elsewhere) | 
| Code | The code (used as the code in the resource instance) | 
| Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application | 
| Definition | An explanation of the meaning of the concept | 
| Comments | Additional notes about how to use the code |
