Citi Benefits Handbook
Predetermination of Benefits
MetLife recommends that you obtain a predetermination of benefits before undergoing any procedure that will cost more than $300. By requesting a predetermination of benefits, you will know in advance how much you will be responsible for paying.
If you do not request a predetermination of benefits, you may find that the Plan will pay less than you anticipated or nothing at all, depending on the procedure and treatment provided.
