Addition of New Function to the Insurers Business Support System
Japan System Techniques Co., Ltd. (JAST) has added a new function to its Insurers Business Support System (iBss),which was launched on October 1, 2020.
JAST started iBss in response to requests from health insurance organizations for assistance for the use of ICT in theirbusiness processes. Centered on an internet validation system, iBss is currently used by more than 100 health insuranceorganizations.
The following charts show the functions of iBss.

1. Release of new functions
On April 17, 2023, JAST will add three functions to the web service system for policyholders and one function to theinsurance business process system for health insurance organizations.
Display of medical examination results

Policyholders can use the web portal to check results of medical examinations. Health insurance organizations that
already use the JAST web portal can use this as a standard function.
Recommended medical examination notices

Using the recommended medical examination notice function with the medical examination result display function
allows displaying exam results as well as comparing exams with invoice data. This makes it possible to encourage
individuals who require an examination but have not yet done so to go to a healthcare facility to perform the examination.
In addition, individualized notifications for applicable policyholders based on the standard numbers of the healthinsurance organization are possible. This allows proactively contacting policyholders. Another advantage is benefit
measurement function for notices and based on whether or not individuals who received notices have viewed theeducation screen and are subsequently receiving outpatient care.

examinations they should be receiving and drugs they should be taking. Just as with recommended medical examination
notifications, this function generates personalized notices for policyholders based on health status relative to thestandards of the health insurance organization used. In addition, this function includes the measurement of benefits
based on notices and whether or not individuals viewed the education screen and achieved an improvement in theirhealth.
The function for providing information to individuals who are 75 or older about the proper use of drugs has been
designated as a service eligible for incentive payments. The distribution of educational publications in the past hasreceived a positive response from many health insurance organizations. Using the internet will allow distributing thisinformation to even more people.
