On a test instance of my own, using OpenEMR 6.1, the menu option looks like this:
Modules > Carecoordination > Send to HIE
There is no option to select just Modules > Carecoordination.
And Modules > Carecoordination > Send to HIE gives:
"A 404 error occurred
Page not found.
The requested controller was unable to dispatch the request.
Controller:
Carecoordination\Controller\CarecoordinationController
No Exception available"
