those of you who have Medicaid. what did you pay to give birth?

I have united healthcare as primary insurance and Medicaid as secondary insurance because through my insurance I will still owe $6,000 for labor and delivery. 
I was wondering if Medicaid would pay for all of that is left after my primary covers it's part? I've called and asked and no one has an answer for me. 
If you gave birth on Medicaid- what did you pay out of pocket? 
Oh and when we're u able to add ur baby to ur Medicaid? We're his shots and such covered before u called Medicaid and added them?
