1.22.2.1.581 Value Set for codes in http://hl7.org/fhir/dataelement-granularity

This is a value set defined by the FHIR project.

Summary

Code System URL:http://hl7.org/fhir/dataelement-granularity
Value Set URL:http://hl7.org/fhir/vs/dataelement-granularity
Definition:Indicates the degree of precision of the data element definition

Formal value Set definition : XML or JSON.

This value set defines its own codes:

This value set contains 6 concepts

1.22.2.1.581.1 DataElementGranularity

Indicates the degree of precision of the data element definition

This value set defines its own terms in the system http://hl7.org/fhir/dataelement-granularity

LvlCodeDefinition
1comparable The 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 The 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 compareable.
2  equivalent The data element allows multiple units of measure having equivalent meaning. E.g. "cc" (cubic centimeter) and "mL".
2  convertable The 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 A convertable data element where unit conversions are different only by a power of 10. E.g. g, mg, kg.
2  flexible The 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.

This value set is used in the following places:

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)
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
DefinitionAn explanation of the meaning of the concept
CommentsAdditional notes about how to use the code

In addition, this page will include mappings to HL7 v2 or HL7 v3 code where these have been defined.
