Does the questioner want to ask "What should I do if the invoices issued by the plastic surgery hospital for loans are different?"

1. First communicate with the hospital's financial department, explain the difference between the loan demand and the invoicing amount, and confirm the final invoicing amount.

2. Secondly, communicate with the responsible staff of the loan institution to explain the difference in the amount invoiced by the hospital.

3. Finally, request additional supporting documents from the hospital to more clearly explain the difference in the invoiced amount and justify the loan.
