### Note

1. Attributes (0040,2016) and (0040,2017) Placer Order Number and Filler Order Number/Imaging Service Request are intended to convey the corresponding order numbers as defined in HL7, in the case where interoperability with an HL7 environment is the objective.

2. Attributes (0040,2001), (0040,2006) and (0040,2007) were previously defined in DICOM. They are now retired (see PS3.3-1998).

3. Both the attribute Requesting Service (0032,1033) and Requesting Service Code Sequence (0032,1034) are defined in this table; the latter has been added and is preferred, but the former is not retired since in some uses it may be copied from an HL7 message without the ability to map it to a coded form (e.g., with only ORC-17 component 1 valued).
