Generated Narrative: ValueSet R5-v3-ObservationInterpretationNormalityHigh-for-R4

This value set expansion contains 4 concepts.

System	Version	Code	Display	Definition
`http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation`	2.1.0	H	High	The result for a quantitative observation is above the upper limit of the reference range (as defined for the respective test procedure). Synonym: Above high normal
`http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation`	2.1.0	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-ObservationInterpretation`	2.1.0	HH	Critical high	The result for a quantitative observation is above a reference level at which immediate action should be considered for patient safety (as defined for the respective test procedure). Synonym: Above upper panic limits.
`http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation`	2.1.0	HU	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.
