1. A method comprising: obtaining a computer code comprising computer commands usable to process insurance claims; building a computer readable directed graph representing a control flow of the computer code, by identifying decisions and actions in the computer code, the graph comprising nodes connected by edges, some of the nodes being decision nodes associated with the decisions and some of the nodes being action nodes associated with the actions; determining, on the graph, benefit action nodes that are each associated with at least one monetary outcome of a specified insurance claim; identifying all logic paths that lead to each benefit action node by traversing the graph from each benefit action node backwards, each logic path comprising a sequence of preceding decision nodes and action nodes connected by edges, each set of paths being associated with a specified benefit action node representing a benefit rule; converting automatically code expressions from the computer code to create natural language benefit rules; and outputting the natural language benefit rules by presenting each specified benefit action in relation to grouped logic paths associated with the specified benefit action; editing automatically the computer code responsive to a specified revision to a specified benefit rule by a user, wherein the editing being performed by converting the revision into a revised control flow, converting the revised control flow into a revised computer code portion, and replacing the computer code portion associated with the benefit rule before the revision with the revised computer code portion; indicating visually at least one specified location on the computer code associated with a specified benefit rule, responsive to a query regarding the specified benefit rule; wherein at least one of: the obtaining, the building, the determining, the identifying, and the outputting and the editing is performed by at least one computer.
