TitleCross-version ValueSet R5.ObservationInterpretationCodes for use in FHIR R4
Realmuv
Authorityhl7
DescriptionThis cross-version ValueSet represents content from http://hl7.org/fhir/ValueSet/observation-interpretation|5.0.0 for use in FHIR R4 that is appropriate for use but unavailable in `http://hl7.org/fhir/ValueSet/observation-interpretation|4.0.1`.
PurposeThis value set is part of the cross-version definitions generated to enable use of the value set `http://hl7.org/fhir/ValueSet/observation-interpretation|5.0.0` as defined in FHIR R5 in FHIR R4. The source value set is bound to the following FHIR R5 elements: * `Observation.component.interpretation` as Extensible * `Observation.interpretation` as Extensible Across FHIR versions, the value set has been mapped as: * `http://hl7.org/fhir/ValueSet/observation-interpretation|5.0.0` * `http://hl7.org/fhir/ValueSet/observation-interpretation|4.3.0` * `http://hl7.org/fhir/ValueSet/observation-interpretation|4.0.1` Note that there are 47 concepts not included in this cross-version definition because they have valid representations. Following are the generation technical comments: One or more source concepts are either not mapped or broader than their targets, so the value set relationship is broadened. The source value set has more active concepts (49) than the target (39), so the source is broader than the target. All concepts in the comparison are listed as identical. The source and target value sets have the same number of active concepts (39).

Narrative

Generated Narrative: ValueSet R5-observation-interpretation-for-R4

This value set expansion contains 10 concepts.

SystemVersionCodeDisplayDefinition
http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  ACAnti-complementary substances present

A valid result cannot be obtained for the specified component / analyte due to the presence of anti-complementary substances in the sample.

Deprecation Comment: This code is being deprecated to match the status in V2 Table 0078 "Interpretation Codes.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  CarrierCarrier

The patient is considered as carrier based on the testing results. A carrier is an individual who carries an altered form of a gene which can lead to having a child or offspring in future generations with a genetic disorder.

Deprecation Comment: This code is currently the same string as the print name for this concept and is inconsistent with the conventions being used for the other codes in the coding system, as it is a full word with initial capitalization, rather than an all upper case mnemonic. The recommendation from OO is to deprecate the code "Carrier" and to add "CAR" as the new active code representation for this concept.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  H>Significantly high

A test result that is significantly higher than the reference (normal) or therapeutic interval, but has not reached the critically high value and might need special attention, as defined by the laboratory or the clinician.

[Note: This level is situated between 'H' and 'HH'.]

Deprecation Comment: The code 'H>' is being deprecated in order to align with the use of the code 'HU' for "Very high" in V2 Table 0078 "Interpretation Codes".

[Note: The use of code 'H>' is non-preferred, as this code is deprecated and on track to be retired; use code 'HU' instead.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  HMHold for Medical Review

Hold for Medical Review

Usage Note: This code is not intended for use in V3 artifacts. It is included in the code system to maintain alignment with the V2 Table 0078 "Interpretation Codes."

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  L<Significantly low

A test result that is significantly lower than the reference (normal) or therapeutic interval, but has not reached the critically low value and might need special attention, as defined by the laboratory or the clinician.

[Note: This level is situated between 'L' and 'LL'.]

Deprecation Comment: The code 'L<' is being deprecated in order to align with the use of the code 'LU' for "Very low" in V2 Table 0078 "Interpretation Codes".

[Note: The use of code 'L<' is non-preferred, as this code is deprecated and on track to be retired; use code 'LU' instead.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  MSmoderately susceptible

The patient is considered as carrier based on the testing results. A carrier is an individual who carries an altered form of a gene which can lead to having a child or offspring in future generations with a genetic disorder.

Deprecation Comment: This antimicrobial susceptibility test interpretation concept is recommended by OO to be deprecated as it is no longer recommended for use in susceptibility testing by CLSI (reference CLSI document M100-S22; Vol. 32 No.3; CLSI Performance Standards for Antimicrobial Susceptibility Testing; Twenty-Second Informational Supplement. Jan 2012).

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  OBXInterpretation qualifiers in separate OBX segments

Interpretation qualifiers in separate OBX segments

Usage Note: This code is not intended for use in V3 artifacts. It is included in the code system to maintain alignment with the V2 Table 0078 "Interpretation Codes."

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  QCFQuality control failure

A result cannot be considered valid for the specified component / analyte or organism due to failure in the quality control testing component.

Deprecation Comment: This code is being deprecated to match the status in V2 Table 0078 "Interpretation Codes.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  TOXCytotoxic substance present

A valid result cannot be obtained for the specified organism or cell line due to the presence of cytotoxic substances in the sample or culture.

Deprecation Comment: This code is being deprecated to match the status in V2 Table 0078 "Interpretation Codes.

http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation2.1.0  VSvery susceptible

The patient is considered as carrier based on the testing results. A carrier is an individual who carries an altered form of a gene which can lead to having a child or offspring in future generations with a genetic disorder.

Deprecation Comment: This antimicrobial susceptibility test interpretation concept is recommended by OO to be deprecated as it is no longer recommended for use in susceptibility testing by CLSI (reference CLSI document M100-S22; Vol. 32 No.3; CLSI Performance Standards for Antimicrobial Susceptibility Testing; Twenty-Second Informational Supplement.
