# Introduction
## Document Purpose
The ICD-10 Technical Mapping Guide outlines the intended purpose, practical use cases, and technical mapping procedures used in the development, publication, and maintenance of the SNOMED CT to ICD-10 map.
The data sets, algorithms, and intellectual products of the SNOMED CT to ICD-10 map are referred to in this document as simply ‘the map’.
## Business Application
The map from SNOMED CT to the International Classification of Diseases, Tenth Revision (ICD-10) has been created to support the epidemiological, statistical, and administrative reporting needs of SNOMED International member countries and their respective WHO Collaborating Centers.
Deployment of the map supports the following business applications:
* re-use of clinical data for additional statistical purposes
* rapid submission and response to national reporting requirements
* saving time and improving efficiency for the coding professional
* improved accuracy and reproducibility of code mapping
* promulgation of widespread comparable epidemiological and statistical data
* cost savings for SNOMED International member countries which maintain ICD-10 derivative product maps
## Use of Language
The ICD-10 map and related documentation are maintained and distributed in US English.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
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-specifications/snomed-ct-to-icd-10-map-specification/introduction/1-introduction.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.
