Per their website, yes:
For any income-driven repayment plan, periods of economic hardship deferment, periods of repayment under certain other repayment plans, and periods when your required payment is zero will count toward your total repayment period.
I'm confused about how interest works when you have $0 monthly repayments (I'm in the same boat)
