Abstract: A system and method for automated coding and testing of insurance benefits is provided. The system comprises a user interface to receive data pertaining to benefits based on insurance benefits contracts and to create Benefit Plan Designs (BPDs) using the received data. The system further comprises a benefits mapping module to map the benefits from the BPDs with pre-stored benefits in a repository. Further, the system comprises a benefit code translator to translate the mapped benefits into codes or mnemonics and a benefit code updating engine to update the codes or mnemonics into one or more claims platforms. In addition, the system comprises a test scenario mapping module to generate test claims and expected results and to execute the generated test claims on the one or more claims platforms to generate actual test results. The system also comprises a validation engine to validate the codes or mnemonics.
