Core Code Systems

CodingQualifierCS

Description TBD

Code Display
preferred_code The preferred, standardized code for interoperability purposes. There should be only one coding in a CodeableConcept with this tag.
source_code The code found in the information source for this entry, e.g., the raw, original, or first encoding.
user_selected_code The code was directly selected by the user, as opposed to being determined after the fact via interpretation of notes or natural language processing.
derived_code The code was determined after-the-fact from source data, either through translation, or via interpretation of free text (by human or machine).
category_code Indicates the code is a less specific term or a categorization of the source or standard code, i.e., a hypernym. For example, a code for 'vital sign' in the context of a body weight measurement would be a category code. Category codes can be useful for search and query purposes.
coded_expression The code is an expression in an expression language defined by the CodeSystem
default_code The code was supplied by the system by default, because no specific coded value was available.

even_chance Roughly equal chance or even odds of happening, between 40% and 60% probability
unlikely Not likely or improbable, e.g., an event with 20% to 40% likelihood
very_unlikely Very unlikely, highly improbable, e.g., an event with less than 20% but non-zero likelihood
