Doctors accepting NJ Family Care
Medicaid has a list of all of their providers and HMO's on line, by state. I don't have the link but you can google it.
If you don't want to google it, you can call the 800 number for your Medicaid coverage and they will give you some names as well.
That'll give you a list of names, and then you can go from there to find out who is considered highly rated.
Good luck=)
