I was knowingly "fraudulently joinded" to a lawsuit and subsequently dismissed from the suit. However, had to pay E & O deductible. Can I recoup this

Depending on the circumstances of the dismissal, you could recoup your costs of defense. Did the judge make a finding that you were "fraudulently joined?" Did your attorney move for sanctions under Rule 11 of the West Virginia Rules of Civil Procedure? With more information, I could give you a more definitive answer.
