Ay, nakakainnovate talaga ang setup na yan! From what I know, most hospitals do include OB fees sa overall hospital bill, but some arrangements, especially kung may complications or if another doctor had to step in, pwedeng ma-settle separately through bank transfer para mas organized ang payment between you and the doctor directly. About the double OB fee though, that's where it gets tricky, a few of us moms have encountered similar situations, and honestly, it depends on kung paano nila na-structure ang billing, pero usually dapat lang na may clear breakdown kung sino ang attending doctor and sino ang consultant lang. I'd suggest asking the hospital's billing department for an itemized breakdown of exactly who charged what and why, it's your right to understand every single charge, especially sa delivery na yon! If something doesn't add up, you can always request a meeting with the billing department or even the doctors to clarify before you fully process the payment.
