Not Offered NT Scan?

Kelly
Hello Ladies!  I am 37 and currently 12 weeks pregnant after mmc in July.  I just took the Counsyl NIPT blood test.  However, I was not offered the 12 week NT Scan.   When I called the obgyn to request it (both are covered under insurance) she refused.  I live in a rural area and there is no other office, which is frustrating because I feel like I would switch based upon her reaction. I know many women over 35 see a maternal fetal specialist too, but I have not been given that option/there is not one where I live.  Anybody else have this happen?  Just the NIPT and not the NT Scan?  In need of some reassurance....
