In the Family Affordability Glitch: Can I still Get Obamacare?

My mother currently does not have health insurance. My father’s employer offers insurance for spouses but it is to expensive for their income. Combined they make around $42,000/yearly, my father pays a $27 premium and it would cost $678 to add my mother onto his employers plan. Is there a way to get covered under Obamacare or do they fall into the family affordability glitch?
