Hi Aamir,
Code Set 72 is Cerner's Clinical Event Codes system. It is entirely customizable by clients, but as you've seen, we do perform targeted LOINC/SNOMED mappings. Code Set 72 is quite large, so while we do perform a standard set of mappings for all clients, we tend to perform targeted mappings on a per-need basis.
Based on your questions, I'm guessing you're asking about
Observations (let us know if not). I don't believe we have any standard set of NICU Observations for clients, but if there is something you'd specifically like to see available in the public sandbox, we can assist there.
Thanks!
Joe (Cerner)
