Miss. Code Ann. § 75-17-7 gives judges in Mississippi discretion to assess pre-judgment interest. The judge has discretion to establish the rate and when the date interest begins to accrue.  However, the starting date cannot be earlier than the date of filing.  The Supreme Court has held that no award of pre-judgment interest is allowed if the amount owed is unliquidated prior to judgment, which should always be true in medical malpractice cases. Coho Resources, Inc. v. McCarthy, 829 So. 2d 1 (Miss. 2002) (a personal injury case); Warwick v. Matheney, 603 So. 2d 330 (Miss. 1992).
