Logical Definition (CLD)

Include codes from http://terminology.hl7.org/CodeSystem/v3-NullFlavor where concept is-a UNK

Expansion

This value set contains 7 concepts

Expansion based on NullFlavor v2.0.0 (CodeSystem)

All codes from system http://terminology.hl7.org/CodeSystem/v3-NullFlavor

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
