Tummy tuck with liposuction varies considerably between cities and states. Cost breaks down to surgeon's fee to perform the operation and provide the postoperative care, anesthesia fee to put you to sleep, facility fee for the use of the operating room, and if you stay overnight, any hospital fees for the overnight stay. My recommendation is to consult with 2 or 3 plastic surgeons in your area to identify what you need done (ie how much lipo? mini or full tummy tuck? etc.) and to receive a quote. This is a big operation and your due diligence will help you in making the correct choice.
