Abstract: Improvements in bandwidth usage, accuracy, and speed are provided when handling ambiguously coded data via a qualification request. Communicating parties, even when conforming to an industry-defined standard, may often include ambiguously coded values in their communications, complicating the communication between entities. To enable parties to use their own interpretations of the standards and receive desired results from the other parties using incompatible interpretations of the standards, synonymous codings are used to identify candidate options prior to transmission to the other party. The candidate options an analyzed according to various rules or courses to quickly and accurately identify a preferred match for a code, which is presented to a user. The user is enabled to update the code to match the other party's interpretation or override the determination to use the original or a different code. The communication is then handled according to the user's code selection.
