Multiple DPC Summit attendees have asked about whether continuing OB is possible within the DPC arena.
Including OB can be tricky. I do not know a lot about Cottontree Family Practice (in Utah), but according to their website their medical services include "complete obstetrical care including delivery."
When it comes to negotiating cash prices for obstetrical care, keep in mind that most hospitals are capable of doing this, but it would probably require persistence on your part. Every once in a while you run across refreshing examples like Good Sheppard Health System where you know up front that the cost of a delivery will be $2,750.
