Question: Does Obamacare provide maternity for married dependents?
Answer: The Affordable Care Act (ACA) includes several categories of essential benefits to set a benefits floor for all health insurance plans from 2014 going forward and maternity and newborn care is one of those categories.
But I think you may be asking another question. It sounds like your married son or daughter is covered under your health insurance policy and you have a grandchild on the way. We don’t know yet how that situation will be covered in 2014, but today, the maternity and delivery costs will not be covered by your health insurance.
