I bought social security and medical insurance in Shenzhen. Can I be reimbursed by medical insurance when I go home to be hospitalized in Hongan County, Hubei Province?

Employees' medical insurance can't be transferred, but they can go to different places for medical treatment.

Go to the local medical insurance bureau in Hubei to fill out the application form for long-term fixed-point residence in different places, get it stamped by the hospital and medical insurance bureau near Shenzhen, and then go back to Hubei medical insurance bureau for approval. You can get medical invoices and details from Shenzhen and go back to Hubei for reimbursement every year.

Pay attention to the fact that invoices cannot cross the year, and invoices within one year should be reimbursed before the end of the year.
