Hey mamsh! Oo, a few of us did this actually, nagbayad kami ng doctor's fee sa private OB namin pero nag-deliver sa public hospital para sa lower hospital charges. Honestly, depende sa OB mo kung gaano ka-steep ang rate, pero usually around 15k-40k lang ang doctor's fee depending sa area at experience ng doctor, tapos bayad na lang separately ang hospital bills sa government, lab work, room, medicines. One of my mum friends says mas sulit kasi ang private doctor attention pero protected ka pa rin ng public hospital safety net, lalo na kung may complications. Better mo din direktang tanungin yung public hospital mo kung ano ang exact rates at kung pwede ba talaga mag-enter ang private doctor, sometimes may requirements sila or need ng coordination.
