I had this info (once upon a time) during my first ... and probably second pregnancy :P
Evelyn's flat rate for prenatal, home birth and postpartum visits - does that fee also include Lab work, 20 week sonogram and Birth assistant fee?
Provider fees do not cover labs and sonos as those services are provided by someone else, i.e. the lab and the radiology business - not connected to the midwife or ob or any other type of health care provider who orders/refers to those services (unless they own the sono machine, but they still charge a fee for the sono). If you have insurance those services are covered by that policy. If no insurance and you want the sono, you can shop around for best price and tell them you are self-pay.
