Genetic testing

My OB office works with Progenity for NIPT testing and I called Progenity just to see what insurances they are in network with and they gave me a quote of $595 self pay. MaterniT21 is free to me as long as a doctor orders it. Has anyone had a Doctor put in a lab order for a MaterniT21 test for them even though the office didn’t directly work with MaterniT21?
