What you can do here
Published centrally, read here
This vocabulary is shared by every clinic on the platform, so it is published centrally rather than edited in your workspace. A vocabulary each clinic could edit would stop being shared, and the codes would stop meaning the same thing between you and anyone you send results to.
A version is published whole
Terms are never edited in place. A new version is prepared in full, checked, and then swapped in as one act. Until that moment you keep seeing the version you already had.
Old versions are kept
When a version is replaced the old one is marked replaced and kept. A result reported last year against a test has to keep meaning what it meant then, even after the code is retired.
The same search the clinical screens use
The search box here is the one behind the ordering and laboratory screens, so if you can find a term here they can too.
What the catalog does not do
It says what a term is and what code it carries. It does not translate between coding systems, check a code against an external register, or decide whether a term is the clinically right one to use.
