Harmony testing

Has anyone got the harmony test done? Was it covered by your insurance? If not how much was it? My husbands cousin has a little boy with Down's syndrome so we may be covered- the OB is still checking. I was wondering about the out of pocket cost in case we aren't covered. I would love to be prepared if there was a trisomy present. I work in a NICU and would never abort but being prepared would be good!
