CDA Document Types allow you to configure a structured document's Type based on the standard TemplateIds located within a CDA.
When you have selected the setting Process Structured CDAs on Intake, the system automatically sets the type for received attachments, based on the association you create here.
You may also set a Default type. If a received document does not have a TemplateId that is associated with a specific type, the system will set it to your Default.
