ObservationMethod

A code that provides additional detail about the means or technique used to ascertain the observation.

Examples: Blood pressure measurement method: arterial puncture vs. sphygmomanometer (Riva-Rocci), sitting vs. supine position, etc.

OpenIssue: Description copied from Concept Domain of same name. Must be verified. Note that the Domain has a full discussion about use of the attribute and constraining that is not appropriate for the code system description. Needs to be improved.

Code	URL	Description	Type
Specializes		The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.	Coding
Generalizes		Inverse of Specializes. Only included as a derived relationship.	Coding
internalId	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id	The internal identifier for the concept in the HL7 Access database repository.	code
status	http://hl7.org/fhir/concept-properties#status	Designation of a concept's state. Normally is not populated unless the state is retired..	code
howApplies	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-how-applies	Haven't a clue!	string
notSelectable	http://hl7.org/fhir/concept-properties#notSelectable	Indicates that the code is abstract - only intended to be used as a selector for other concepts	boolean
