Abstract: A healthcare insurance claim that includes variables characterizing aspects of a healthcare service for which reimbursement is sought is analyzed in order to determine whether there are any aspects that are indicative of fraud or error. This analysis includes generating score variables from the variables of the healthcare insurance claim and determining whether a presence of one or more of the pairs of variables is indicative of fraud or error based on levels of co-occurrence of the one or more pairs in historical healthcare insurance claims. If a positive determination occurs, then the healthcare insurance claim can be flagged or elevated for review by a user. Related techniques, apparatus, systems, and articles are also described.
