Extension: uncertaintyType

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/iso21090-uncertaintyType

Status: draft. Extension maintained by: Health Level Seven International (Modeling and Methodology)

A code specifying the type of probability distribution for the uncertainty.

Comment:

This is only meaningful if there is also an uncertainty extension. If there is an uncertainty extension with no type, this means that the probability distribution type is unknown. In that case, the uncertainty has the meaning of an informal guess.

Context of Use: Use on Element ID Quantity
