I have the need to represent doctors' textual (plain-word) notes, or descriptions, within a HL7 CCD document. I tried to analyze it and I think I got the relation between narrative and entry blocks, but I can't seem to find a way to insert a regular textual note in there without breaking the standard.
Is there any suggestion or guide on this matter?
There is a Comment Activity entry template in the C-CDA spec that is:
templateId: 2.16.840.1.113883.10.20.22.4.64 (open)
Comments are free text data that cannot otherwise be recorded using data elements already defined by this specification. They are not to be used to record information that can be recorded elsewhere. For example, a free text description of the severity of an allergic reaction would not be recorded in a comment.
But you need to verify if your section level template allows to use free text comments. There may be cases when it specifically prohibits this.
