# relationship group

## relationship group

**This is used to refer to a group of relationships representing an attribute group.**

## attribute group

An association between a set of attribute value pairs that causes them to be considered together within a concept definition or postcoordinated expression.

#### Notes

* When an *attribute group* is represented as a group of defining relationships it is usually referred to as a *relationship group.*

#### Example

* [| Cholecystectomy with exploration of common duct|](http://snomed.info/id/45993005) has two different attribute groups:
  * [| Method|](http://snomed.info/id/260686004) [| Exploration - action|](http://snomed.info/id/281615006) *is grouped with* [| Procedure site - Direct (attribute)|](http://snomed.org/fictid) [| Common bile duct structure|](http://snomed.info/id/79741001)
  * [| Method|](http://snomed.info/id/260686004) [| Excision - action|](http://snomed.info/id/129304002) *is grouped with* [| Procedure site - Direct (attribute)|](http://snomed.org/fictid) [| Gallbladder structure|](http://snomed.info/id/28231008)
* If these attributes were not grouped, this procedure would incorrectly classified as a subtype of [| Excision of common bile duct|](http://snomed.info/id/6402000) .

## Alternatives

* **Relationship group**
