OpenEMR 8.3 Patient Issues Medication search does not return installed RXCUI codes

I am testing a fresh OpenEMR 8.3.0 Docker installation.

Environment:
OpenEMR 8.3.0, official 2026-08-21 image
PHP 8.5.6
MariaDB 11.8.8

I enabled the RXCUI code type and marked it as a Drug code type. I then imported the NLM RxNorm Current Prescribable Content release through Admin → Coding → Native Data Loads.

The import appears successful. Direct database verification shows 88,000 RXCUI records. For example, searching the codes table directly for “Motrin” returns multiple entries including RXCUI:202488 Motrin.

In Patient Issues → Medications → Add/Edit Issue, the “Select from list” box still contains the three default shortcut medications (Metformin, Norvasc, Lipitor). I understand that this appears to come from medication_issue_list and is probably expected.

The problem is the medication Title/code search: searching for “Motrin” does not return the installed RXCUI concepts even though RXCUI is active, marked Drug, and the records are present in the database.

Is there another configuration required for Patient Issues medication search to use an active RXCUI Drug code type, or is this a regression/bug in 8.3?

Expected behavior: the medication issue code search should allow selection of installed RXCUI drug concepts and store the selected RXCUI code with the medication issue.

I can provide SQL results/screenshots or test a patch if useful.
