If tissues at the root crown were protected enough so they didn't freeze, and of course - the roots are still viable, it will come back. If it does, I wouldn't be too surprised if you notice some badly deformed leaves for a while due to the cold. Prune away any mushy dead growth. Keep it on the very dry side while you wait to prevent root rot.

Hey Sunshine,

I dug up my small elastica from the yard after several nights in the low twenties, and I think one in the teens. I kept it semidry in the basement all winter. It started sending up new albino branches after a couple months. It is still inside, but in the sun and looking good now. I cut away all the dead braches. Ficus elastica is comoonly considered a dieback in zone 9. Maybe try roxburghii (sp?) for your zone. Woodlanders has a dieback for zone 8. Maybe it could be deciduous for you in zone 9.
