Processing arrangements and methods are provided for the automated decoding or translation of information in healthcare data records, which are coded in a non-standardized or varying formats. A data record which contains information, a portion which is recognized and another portion of which is new, is decoded or translated using a statistical mapping rule. The mapping rule assigns a most likely translation value to the information based on the recognized portion of the information. The statistical mapping rules are established by analysis of a set of previously decoded data records.
