Code | Display | Definition |
UNK | unknown | **Description:**A proper value is applicable, but not known. **Usage Notes**: This means the actual value is not known. If the only thing that is unknown is how to properly express the value in the necessary constraints (value set, datatype, etc.), then the OTH or UNC flavor should be used. No properties should be included for a datatype with this property unless: 1. Those properties themselves directly translate to a semantic of "unknown". (E.g. a local code sent as a translation that conveys 'unknown') 2. Those properties further qualify the nature of what is unknown. (E.g. specifying a use code of "H" and a URL prefix of "tel:" to convey that it is the home phone number that is unknown.) |
ASKU | asked but unknown | Information was sought but not found (e.g., patient was asked but didn't know) |
NAV | temporarily unavailable | Information is not available at this time but it is expected that it will be available later. |
NASK | not asked | This information has not been sought (e.g., patient was not asked) |
NAVU | Not available | Information is not available at this time (with no expectation regarding whether it will or will not be available in the future). |
QS | Sufficient Quantity | **Description:**The specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material. e.g. 'Add 10mg of ingredient X, 50mg of ingredient Y, and sufficient quantity of water to 100mL.' The null flavor would be used to express the quantity of water. |
TRC | trace | The content is greater than zero, but too small to be quantified. |
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 |
