it's possible yes. if you get your insurance at work the affordable care act does require that young adults up to the age of 26 remain covered. however your company may not be required to cover maternity. though maternity coverage is part of the essential health benefits that individual and small business plans must cover many large employers are exempt from having to comply with this part of the law for dependents.
can my health insurance deny maternal/prenatal care to my dependent if the coverage started in january of 2014?
