Houseplant question: caring for a "money tree"?

For many years I had a potted plant called a money tree (no joke, that is the actual name of the plant. Alas, dollar bills do not grow on it). It grew well and I repotted it as it grew… At one point the leaves started falling off. I tried putting it outside, but then forgot about it. I just noticed that it did really poorly outside and lost all its leaves. Is there anything I can do to revive it if I bring it inside?
