Standardizing Codings

Often, you will receive data that uses inconsistent or non-standard codings. The Terminology API helps you to identify and standardize these codings using well-known reference code systems.

For example, you may have a patient record with a medication coded simply as “59310057922”, without knowing which code system it’s from. You can use the Standardize API to look up the mysterious code:

{
    "coding": [
        {
            "system": "http://hl7.org/fhir/sid/ndc",
            "code": "59310057922",
            "display": "NDA021457 200 ACTUAT Albuterol 0.09 MG/ACTUAT Metered Dose Inhaler [ProAir]"
        },
        {
            "system": "http://www.nlm.nih.gov/research/umls/rxnorm",
            "code": "2123072",
            "display": "NDA021457 200 ACTUAT albuterol 0.09 MG/ACTUAT Metered Dose Inhaler"
        }
    ]
}

Based on the results, you may conclude that the original data was using the NDC code for Albuterol.

Leveraging the Terminology API in this way, you could standardize data to use well-known code systems.
