There are many implementation solutions for primary, assisted and secondary
In assisted coding what you mention is one way.
The best solution IMO that I saw implemented is free text search, matching
to an interface terminology that internally maps to SNOMED. The interface
terminology is controlled, and based on real terms gathered from users, so
this methodology adapts to the location and usage. And what the wizard
provides are alternative and suggested terms from the interface
terminology. Everything is a tree here but no tree is shown to the end
user, they just see free text suggestions for his/her input. A team of
experts maintains the interface terminology and mappings to SNOMED.
Mappings to other terminologies can be done, for instance with LOINC, or
even ICD for statistics.
This is the approach of a health provider in Argentina and is the way the
national EHR strategy is being implemented in Uruguay. I think Chile will
also follow those steps.
