2.8 Purpose

Represents the specific reason for which the summarization was generated, such as in response to a request.

The general use case does not require a purpose. Purpose should be utilized when the CCD has a specific purpose such as a transfer, referral, or patient request.

NOTE: Purpose is represented as a document body section in CCD. The template identifier for the Purpose section is 2.16.840.1.113883.10.20.1.13.

CONF-15: CCD MAY contain exactly one and SHALL NOT contain more than one Purpose section (templateId 2.16.840.1.113883.10.20.1.13). The Purpose section SHALL contain a narrative block, and SHOULD contain clinical statements. Clinical statements SHOULD include one or more purpose activities (templateId 2.16.840.1.113883.10.20.1.30).
