RxNorm for Developers: RxCUI Resolution Without Guessing

A practical guide to treating terminology resolution as observable application behavior.

Understand RxCUI boundaries

Understand RxCUI boundaries is the first design decision for RxNorm guide. A practical guide to treating terminology resolution as observable application behavior. Write the boundary down before choosing endpoints or drawing clinical-looking UI so reviewers can test the actual promise.

Report resolution methods

For RxNorm guide, report resolution methods should remain observable rather than becoming hidden adapter behavior. Give resolution, lookup, and interpretation separate states, then decide which failures a user may retry.

Handle ambiguity and outages

Handle ambiguity and outages needs an operational test, not only a happy-path example. Add a bounded timeout, stable error handling, request IDs, privacy-safe logging, and a fixture that proves the RxNorm guide workflow fails closed.
