As the 2008-2010 specials, which included Billie Piper's final to date appearance as Rose Tyler in "The End of Time", are officially continued a continuation of Series 4, the answer has to be that Rose has yet to appear again in the series. In "The Day of the Doctor", Billie Piper appears as The Moment, who takes the form of Rose!Bad Wolf. The closing credits erroneously credit Piper as playing Rose in the episode, but she does not.
