Regulatory/legal/billing requirements

Hi all, Struggling to find resources on actual REQUIREMENTS for documentation & communication. I found one BCBS document that discusses monitoring times and what’s approved (or not).

I assume there are no actual laws, so I guess I’m asking for billing purposes. I need to cite my sources for our procedures.

How much does the interpreting physician need to talk to us? How quickly? Do we HAVE to say that the “surgeon acknowledged” our comment? (I definitely think we should for legal coverage, but can I cite a resource for it?)

I appreciate any help or tips you’ve got, thanks!
