I just had it done by Bo Shen It is VERY hard to judge cost in the US. My impression is that Columbia charges A LOT but my insurance negotiated a much lower rate. I think it was about 5,000 for Dr Shen for the surgery and then the hospital charged about 6,000. My insurance is paying Dr Shen 2500 and I don't know what they will pay the hospital because it is still being processed. I expect they will pay closer to 3,000. The preliminary visit was billed as 820.00 and but he was actually only paid 120.00. I would expect to pay 20% of 5-6K for the procedure assuming you don't have anything that needs follow up.
My procedure went great I had minor soreness from the scope and no bleeding. I was able to eat normally within a day and had no discomfort a week later but I had ongoing pouch issues before the procedure.
If you decide to travel to NYC, look into getting an AirBnB in the area instead of staying at the hotels they suggest. We found a great place for less than half the price of a hotel room and we had a kitchen and two bedrooms. Feel free to message me for more info if you want it
Good luck
