Maternity Care Not Covered By Employer?

Is it true that Obamacare requires all insurance companies to cover the cost of pregnancy care, including labor and delivery?

I am inquiring because we have had Anthem Blue cross for years thru my husbands work. Which includes myself, my husband, and our daughter, now 17 and pregnant.

Originally, we apparently opted not to cover pregnancy. However, after several phone calls and a huge bill they refuse to cover our daughters pregnancy.

We are getting very discouraged due to the fact that medi-cal has denied her also, stating she has private insurance, which is true. However, Anthem will not allow us to drop her from our policy, due to their policy. My daughter needs paternal care and we cannot afford to pay out of pocket. Any suggestions?
