CodeSystem: ObservationMethod


Defining URL:http://terminology.hl7.org/CodeSystem/v3-ObservationMethod
Status:Active as of 2019-03-20

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.

Publisher:Health Level 7
Content:Complete: All the concepts defined by the code system are included in the code system resource
OID:2.16.840.1.113883.5.84 (for OID based terminology systems)

This Code system is referenced in the content logical definition of the following value sets:


SpecializesThe 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
