This Code system is used in the following value sets:

4.2.12.426.1 Content

4.2.12.426.2 DataElementStringency

Indicates the degree of precision of the data element definition.

This code system http://hl7.org/fhir/dataelement-stringency defines the following codes:

LvlCodeDisplayDefinition
1comparable ComparableThe data element is sufficiently well-constrained that multiple pieces of data captured according to the constraints of the data element will be comparable (though in some cases, a degree of automated conversion/normalization may be required).
2  fully-specified Fully SpecifiedThe data element is fully specified down to a single value set, single unit of measure, single data type, etc. Multiple pieces of data associated with this data element are fully comparable.
2  equivalent EquivalentThe data element allows multiple units of measure having equivalent meaning; e.g. "cc" (cubic centimeter) and "mL" (milliliter).
2  convertable ConvertableThe data element allows multiple units of measure that are convertable between each other (e.g. inches and centimeters) and/or allows data to be captured in multiple value sets for which a known mapping exists allowing conversion of meaning.
3    scaleable ScaleableA convertable data element where unit conversions are different only by a power of 10; e.g. g, mg, kg.
1flexible FlexibleThe data element is unconstrained in units, choice of data types and/or choice of vocabulary such that automated comparison of data captured using the data element is not possible.

Explanation of the columns that may appear on this page:

LevelA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
