3D or 4D level 2 sonogram

I was wondering if any of you mommies had your level 2 sonogram and if it was a 3d or 4D sonogram? Where did you go to have it done? I will probably have to make an appointment for my level 2 after my next doctors appointment . I would like to see if I could go somewhere that offers it. I want to check to see if my insurance will cover it.
Any help would be appreciated.
Thanks
