Embedded Classification Tool (ECT)

What's new in version 1.5

More detailed coding by providing foundation URI

In this version, the Embedded Coding Tool, can capture more detail than the available codes in the classification by providing the foundation URI.

IMPORTANT! To benefit from this, you need to save the foundationUri returned from the ECT callback. The linearizationUri and now being deprecated uri fields just capture the linearization URI which contains the same level of granularity as the ICD-11 code.

Other enhancements

  • When available, the improved details section also provides a direct link for the related categories in the perinatal chapter.

  • The Embedded Browser introduces new callbacks: browserLoadedFunction fired when the browser has fully loaded and browserChangedFunction fired when the browser content has changed.

  • Upgrade to version 1.5 is safe. There are no breaking changes moving from old versions (1.1, 1.2, 1.3 or 1.4) to this version.

We highly recommend upgrading your current ECT to version 1.5
