Extensions


This version of the PS-CA Implementation Guide has been superseded by a newer version. A full list of versions & releases of the PS-CA Implementation Guide may be found at Guides.


The profiles in this specification make use of the extensions that are maintained by external specifications, notably extensions published by IPS-UV and the CA Baseline.

These extensions are socialized to ensure that if the data is available (and appropriate) to include in a patient summary, that the modeling of that data will be consistent.

Note: Implementors should be aware of known issues that the Simplifier tool has for rendering extensions.

  • Extensions on elements with choice of data type will not render in the differential when displayed in Simplifier. In these cases the extension will be called out.
