Accession numbers are typically assigned by a diagnostic imaging system or clinical laboratory system and depending on the domain an accession number may for example identify a specimen, imaging examination, or biological polymer sequence.

Usage Notes

It is preferable that an organisation uses their own local system identifier namespace but if that is not available then an organisation can use their HPI-O to construct a legal globally unique identifier system for their local identifiers.

See the Australian Digital Health Agency’s R4 FAQ for guidance on constructing an HPI-O scoped^[1] accession number.
