Should I Pay for Blepharoplasty Surgery Upfront?

  IMHO, this is the standard paractice of most good physicians who do this kind of work.

It is quite the norm for plastic surgery patients to pay the full amount in advance of the procedure date. As the other surgeons here have pointed out this is common practice for nearly every office. We have a policy of having patients place a 20% deposit at the time of booking. This essentially reserves that time slot for their scheduled case. Two weeks prior to the surgery we then request the remaining balance to be paid in full.

By that point the surgery schedule has been established for the coming weeks. The anesthesiologist has reserved that date and time for the case and the facility has booked sufficient staff to be present. This requires a high level of commitment by many involved parties just for that case. If payment was not required in advance and a patient decides to cancel the surgery last minute (barring a legitimate emergency), all of the involved parties (surgeon, anesthesiologist and facility staff) would have insufficient time to salvage the day by booking another surgical case.

Paying for surgery in advance is the rule of thumb. It may seem questionable asking for payment two weeks in advance, but it really makes sense when you think about the preparations involved. The operating room needs to be reserved and so does anesthesia.
That sets three or four people's schedules in motion and also requires their payment in advance. The surgeon is reserving his/her time for your procedure, which takes it away from other patients who might want the same date. Your surgeon might miss out on caring for another patient who wants the same date because of your reservation of that date. That is why procedures are paid for in advance of surgery.
Also be aware that most offices will take a non-refundable deposit to hold a date (this can be part of your payment in full if you never left a deposit). Be sure to know the policy when paying. The deposit helps off-set the costs of a last minute cancellation. In most cases, you can apply everything you have paid to another date in the event that you need to cancel and reschedule. If you need to completely cancel the procedure, more than likely you will forfeit some portion of your payment.
I hope this info helps!
