Yeah. (I didn't include that as it seemed like the person above was writing specifically about provider-provider sharing, and while I know provider-BA sharing is fine in the course & context of administering care, I was less sure about provider-provider. But I think there are plenty of examples of this in my own HC, such as when I go for a blood draw and I get 8 bills. But again: HIPAA really doesn't throw too many surprising curve balls here.)

And yeah, lots of HL7v2. (for readers: HL7v2 is a protocol for medical data sharing. Predates FHIR, and is muuuuch uglier. FHIR is JSON/HTTP, albeit complicated, because medical. HL7v2 is custom binary (or I think there's an XML variant that I pray I never run into?). Not to be confused with the organization HL7.

HL7v2 is also the reason for a lot of having to deal with IPSec tunnels, something else I could stand to never see again.)

> And anyone who has dealt with those standards knows that just because EHR vendor A says they support them, and EHR vendor B does, doesn't mean data sharing will be smooth.

Yep. Some unintentional (the standard is complex, people make mistakes), some intentional (the standard permits extension, and obviously custom extensions might not port).

And that's like every other standard an eng on HN is going to interact with, really.
