Chapter 04 · Terminology Bindings · Beat 1 — Which codes?
Last chapter we built the Coding. Now — which systems fill it.
A CodeableConcept holds a system, a code, and a display. This chapter answers the question that leaves open. We map the five code systems clinicians actually use, learn the four binding strengths that decide what is allowed, and run the three terminology operations that make codes queryable.
What you will be able to do
Code systems — SNOMED · LOINC · RxNorm · ICD-10 · UCUM
Binding strengths — required to example
Tx operations — expand · validate-code · translate
And one trap
One of these five systems will cost you money — we get to that
