It wasn't healed completely. Kabuto said that despite absorbing a lot of Bee's chakra, Nagato was still really immobile. The damage that Nagato received from the Gedo Mazo appears to be irreversible, otherwise he would have healed himself, Pain would literally not exist, and Nagato would just wreck house by himself.

If single body healthy Nagato and Konan went to invade the Leaf, it would be GG.
