Hello A.,
I have a friend who worked at Clinica de la Mama. It is a place that does Ultrasound and prenatal care for a set price. You will see mostly the latino population here (becasue most are illegally in US and do not have health insurance) I'm sure they could help you.
The other option is to talk to the office manager of the OB/Gyn you have. I work in the medical field as a sonographer and I hear this all the time. They will work with you-they would rather work with you to get some $$ than none. They have to treat you if you go to the hospital in labor, and if you can't pay the hospital has to write it off-raising everyones premiums. (I see this all the time also). Try your dr. first and then if you cannot get it worked out, try Cobb Gynecology. If you feel uncomfortable talking to them, send them a registered letter worded in a very nice way asking to get a total price for your care. If they will do it they will call you back. Good Luck, R.
