Vietnam has about 80.9 million citizen participate in Healthcare Insurance that makes the coverage of over 86% of the population. VSS now faces big challenges in HI payment inspection: how to manage the huge amount of HI participant data (hundreds of million HI payment requests need inspection annually and increasing) as well as to provide timely resolutions for all HI policies and ensure the quality of social security. It was in this situation that VSS decide to build the HI Inspection Information System to connect with over 12,000 hospitals nationwide. This system has been proved to be a vital point in controlling, monitoring the medical services involved both hospitals and HI participants, and thus, contribute to the overall national social security.
