I'm on medical idk if it's the same but I had to goto my primary care doctor and have them give me referral to see an ob/gyn and they were the one who referred me to the one I currently goto.
I just called a doctor my friend had used &asked if they accepted medicaid. If they do they will tell you which kinds &what not
Just look up OBGYN in ur area, pick which one you like, and once you call ask if they accept medicaid. Thats all you have to do.
I agree with destynee ^ also ask friends and families for any references on good OBs
