Philhealth

Hi! I'd like to know kung magkano yung kayang i-cover ni Philhealth sa delivery? Ilang percent? Or depende ba yun sa kung ilang year ka nang naghuhulog and how much yung nahulog mo? Or can they cover everything? First time mom here. Thank you in advance sa mga sasagot. ? Also, do i need to file any paper sa mismong office nila?
