1. The detailed rules of medical insurance policies vary from place to place, and the local medical insurance bureau shall prevail. You can log on to the local labor and social security information network for inquiry, or you can call the labor and social security consultation telephone number 12333 for consultation, so as not to misunderstand your own major events.

2. Tianjin Labor and Social Security Network/Check it yourself, I won't help you;

3. Generally speaking, the medical insurance paid by the unit can be reimbursed in the next month, while the medical insurance paid by the individual is a waiting period of 6 months; After you change from the original unit to your own payment, your identity should be individual payment, and there may be a waiting period (it is best to call 12333 to confirm);

In addition, I would like to remind you that plastic surgery is not reimbursed by medical insurance in many areas. I don't know the specific situation of "oral frontal osteotomy", but it sounds a bit like plastic surgery. You'd better consult the local medical insurance bureau and the local hospital for confirmation.
