My wife became an insured person under her part-time employer’s health insurance. Since her income averages 90,000 yen/month and satisfies the dependent certification criteria, can she continue to receive medical treatment under her Hitachi Health Insurance status?

 

When a dependent becomes an insured person under his or her employer's health insurance, his or her eligibility as an insured person takes priority. 
You must complete the procedures required to remove her as a dependent.

Please submit the Notification of Health Insurance Dependent Change (Removal) (T-012) promptly to complete the procedures for withdrawal from the Hitachi Health Insurance Society.
At that time, please return any certificates issued by Hitachi Health Insurance (e.g., eligibility certificate, etc.) you have.
