I know the IRIS concerns were:
Changed MSH 4 from FT HALL H CT to ^Org ID ( ^1501 or^5648);
in RXA 11 change to ^^^OrgName&ORGID (^^^Not Tsoo Gah Nee&1501 or ^^^Not Tsoo Gah Nee&5648)
While I know we can assign values in both fields, am pretty sure the issue with the up hat still stands.
I am also including Nathan as he reviews these issues with regard to the standard and where there is a standards compliant way of handling things, he’ll suggest it. If it is something that the IIS might address, I’ll contact someone at CDC to communicate with them on this.
