If you are a single mother under 21 years of age, you need to register as a Philhealth member.
The Section 10, Rule II, Title III, page 26 of the National Insurance Act of 2013 says:
Section 10. Emancipated Individual or Single Parent
Any person below 21 years of age, married or unmarried but with a child, shall be enrolled as a member.
What’s the benefit of being a Philhealth member?
So your child will have Philhealth coverage.
If you remain a dependent, your child will not be covered by your mother or father’s Philhealth membership.
Additional reminder: If you’re younger than 19, and you want to use Philhealth for your delivery, you should give birth in a hospital, not at a lying-in or maternity clinic. Source: Maternity Care Package Rules
