Hi Eric,
We are implementing this same interface. We are sending raw through the engine from STAR to HPF. On the STAR side, the 2.2b interface is a new feed to the engine for us, and McKesson set it up using the HPF message formats; so we aren’t utilizing any HL7 in the routing.
If your STAR 2.2b feed is set up the same way, you shouldn’t need to use any HL7 formats.
