Hi po! I haven't given birth sa Diliman Doctors myself, but a few of my mum friends did last year and ang bills nila ranged quite a bit depending sa type ng delivery and room choice, normal delivery was around 80k-120k, while CS went higher, 150k-200k+, plus anesthesia and meds pa. Better to call them directly kasi sobrang nag-vary based sa your insurance, room type (private, semi, ward), at kung may complications, kaya baka mas accurate yung actual quote nila for you!
