Strictly speaking, C-CDA is consolidated CDA. It is an IG - Implementation Guide. In simple terms, there are various IG for generating a CDA document HITSP/C83 for one is an example and there are several others. The main problem with all these seperate IG is that they are not uniform. C-CDA was created to bring uniformity of data. This presentation here is a good place to start. Basically, it says you got to have at least 4 mandatory section in your CCD, and rest optional sections. It entirely depends on your use case.

Secondly, You need to download a copy of a valid C-CDA file from this site . Let's take inpatient summary document. So that would be your target document, and consider it as a template.

Third, You got to tell your engineering team or if you are the developer yourself, then you need to build logic to extract and place information into that template. This is an iterative process, and everytime you need to validate your developed document, against the validator (site given above).

Until and unless the validator says 0 errors present, your document is not ready.

So, There does not exist a ready made code or logic that you can just plug and play and start developing C-CDA documents.
