hi, I would like to know is that necessary for 20th week ultra sound scanning. Because that not covered with my insurance. I have to pay deductible and co pay 30%. I dont know what to do. Is this u/s is for what purpose to take, To know the gender or something else. Need your advise. I checked with the radiology, they said without insurance 500 $, But i dont know if it goes to Insurance it will be the same amount or it may go more.
