Sending a local code without translating it, using a code from the wrong code system, or a typo in the code.
How to fix it

The snippet below triggers the error:

"intent": "order",
"subject": { "reference": "Patient/example" }
}Frequently asked questions
What is the difference between a required and an extensible binding?
A required binding means the code must come from the value set, with no exceptions. An extensible binding allows an outside code only when the value set has no suitable concept. This rule reflects a required-style check.
