Composition $convert

post/Composition/$convert
Page View

This resource can be used to convert data between Clinical Document Architecture (CDA) and FHIR®. Use the general $convert operation to translate to FHIR®, and use the specific $convert-to-cda for translating to CDA. Learn about translating between FHIR® and CDA.

Supported fields and schema examples

We support any valid FHIR® field. However, we only display fields we’ve defined in our schema, which are usually based on what’s included in the U.S. Core profile. We recommend relying on U.S. Core requirements.

Our schema examples show the shape and possibility of each FHIR® resource; they aren’t code for real-time API calls. We don’t currently recommend copying and pasting these schema examples for your API calls. Consider reviewing FHIR® API actions for realistic examples for particular use cases.

$convert

Translate CDA entries to FHIR®.

The request contains the original CDA data, which is returned as a FHIR® bundle.
