Using Order codes for reports

We’re considering encoding Micro reports (bacteriology, parasitology, virology, mycology, mycobacteriology) from VistA in FHIR. There are order codes but we can’t use them because the result relationship we can trace is : (indeterminate). We can assert, though, that a result from the Bacteriology table is Bacteriology, etc.

We identified these LOINC codes for the 5 domains:
92894-5 Microbiology - bacterial studies Microbiology - bacterial studies Find Pt ^Patient Doc Order
92893-7 Microbiology - viral studies Microbiology - viral studies Find Pt ^Patient Doc Order
96397-5 Microbiology - mycobacteriology studies Document Microbiology - mycobacteriology studies Find Pt ^Patient Doc Both
96398-3 Microbiology - mycology studies Document Microbiology - mycology studies Find Pt ^Patient Doc Both
92892-9 Microbiology - parasitic studies Microbiology - parasitic studies Find Pt ^Patient Doc Order

Problem: 3 of them specify that they are to be used for “Order” rather than “Observation” or “both”. How strictly should we interpret that property? The guide (9.1.3) says this is “not a normative or binding resolution,” so I think we should be OK, but wondering about other perspectives.
