Ay mamsh, honestly hindi ako 100% sure sa exact coverage kasi depende talaga sa insurance plan mo and kung anong arrangement ang setup ng OB mo sa public hospital, better call your OB's clinic directly para clarity, or ring up ang PhilHealth mismo para sure-sure na. A few of my mum friends have private OBs but nag-deliver sa public, and ang professional fee nila ay hindi covered ng PhilHealth, pero covered yung hospital charges, kaya sobrang mahal pa rin overall, pero mas manageable kaysa lahat private, so it really varies po talaga!
