Are there any additional things to check besides the procedure cost during the consultation?

While comparing filler prices, I realized that I should first check what items are included in the quoted price.

I am wondering if product dosage, anesthesia costs, or post-procedure follow-up fees may vary from hospital to hospital.

For those who have actually received a consultation, was there a difference between the initial quoted amount and the final payment amount? I would also like to know what items are good to check in advance.
