it depends. plans sold to small businesses must provide maternity benefits. large firms are not required to do so by law though it's very rare to find a large firm that offers health insurance that doesn't also cover maternity care. if you're eligible for insurance as part of your job you should be covered for maternity care though you can be required to wait for a period of up to 90 days to gain access to insurance.
i am pregnant and going to interview for a new job. will the new health insurance cover the pregnancy?
