Prenatal fees

Hey there so question for other moms- has anyone else’s OB-GYN charged them for a global package for their pre-natal visits & delivery fee? I have 100% prenatal coverage through my insurance however my OB is telling me that they charge one big fee ($2500) which includes prenatal visits & delivery. Just confused bc my prenatal visits would be free if they charged it a different way through my insurance. Or does anyone have a good OB who does not charge globally? Thanks 💕
