# Neoplasms

All source concepts representing neoplastic disorders will be mapped. Map Groups will specify the ICD-10 code(s) from ICD-10 Chapter II Neoplasms for the concept. Morphology mapping with ICD-O is out of scope for this map. The map advice, POSSIBLE REQUIREMENT FOR MORPHOLOGY CODE, signifies the need to add a morphology code if required by the end user.

#### Example

[32398004 |Primary malignant neoplasm of bronchus (disorder)|](http://snomed.info/id/93734005)

Map to **C34.9 Malignant neoplasm: Bronchus or lung, unspecified** , with map advice POSSIBLE REQUIREMENT FOR MORPHOLOGY CODE.

## 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/mapping-heuristics/6.10-neoplasms.md?ask=<question>&goal=<endgoal>
```

`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.
