Code Set Lookups
- Aryn Wiebe
When you need to validate and normalize field values against code sets, you can use lookup functions to execute the mapping. This is useful when you don’t have the data immediately available.
There are various options for performing lookups. In IguanaX, you can use:
With the Codemap Library you can:
Confirm an incoming value is contained in a code set.
Translate from one value or code set to another.
Sometimes you will need to perform an external lookup against a database or API to get the information you need to complete processing.
It’s useful when you don’t have the data within the current system, you can look them up elsewhere.
If these lookups are done across various interfaces, they are best stored in a library.
In the example screenshot below, on line 13 the getNPI function is called to query an external database for the matching NPI based on the provider name from the inbound HL7 message.
