I've been approved for Virginia Medicaid, but I don't have an MCO or RxBIN number yet. Is there a way to get a prescription refill now or do I need to wait for the MCO?

I now have a Medicaid ID# and my coverage has apparently already started, but the MCO is not supposed to take over until September 1. Which means I don't have an RxBIN number or ID card yet.

Am I gonna have to wait until September 1 to get a refill for my meds?
