The table below lists some examples of Members who have published national editions of SNOMED CT. Please note that the International Edition is translated into Spanish. However, this translation is performed by SNOMED International, and is therefore not distributed as a national edition. **Table: Examples of national SNOMED CT editions** |

## US Edition The image below shows the four modules contained in the 20170901 US Edition, together with their module dependencies. Two of the modules are from the 20170901 US Extension, and the other two are from the 20170731 International Edition. Please note that the module dependencies (shown as grey arrows) are date specific, so each versioned source module is dependent on a versioned target module. The module names in this diagram have been shortened for brevity.

Provide Feedback [^1]: Note that although the [| SNOMED CT to ICD-10 rule-based mapping module|](http://snomed.info/id/449080006) is included in the International Edition release package, it is not considered part of the formal International Edition and extensions are not required to reference this module. [^2]: Note that the UK Clinical Edition contains the International Release and the UK SNOMED CT Clinical Extension of SNOMED CT only (not the UK Drug Extension). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.snomed.org/snomed-ct-practical-guides/snomed-ct-extension-guide/4-logical-design/4.4-editions/4.4.1-national-editions.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
