Definition for Value SetDataAbsentReason
This value set has an inline code system http://hl7.org/fhir/data-absent-reason, which defines the following codes: unknown asked temp not-asked masked Using "masked" may be breach of security or confidentiality, but there are times when its use is required to support alternate workflows for gaining access to denied information. unsupported astext it may be linked by internal references (e.g. xml:id). This usually implies that the value could not be represented in the correct format - this may be due to system limitations, or this particular data value error NaN NaN, standing for not a number, is a numeric data type value representing an undefined or unrepresentable value.
