Data Type Profile: Identifier: Accession Number

This profile on Identifier represents the Accession Number for the Imaging Order.

Within a Hospital Information System environment, accession numbers will usually uniquely identify a manifest or report but are not required to always map 1:1 with a report or manifest due to certain imaging workflows. The imaging report may not be uniquely identified by accession number in an overread scenario (two radiologists reading a single imaging study). The manifest may not be uniquely identified by accession number in the case that the RIS imaging request (accession number assigner) requires two imaging modalities to perform the exam, and thus produces two image manifests.

In order to ensure uniqueness across Hospital Information Systems, accession numbers are required to have a system value that identifies the namespace for the issuing authority (ensuring their global uniqueness).
