Quoted $13,000 for Breast Augmentation. Is this very high for Denver?

I can't comment on Denver specifically, but there are definitely surgeons doing great breast augmentations that will cost you WAY less money.
For example, my practice in Alabama performs hundreds of breast augmentations per year and we never charge over 6000 even for the MOST expensive implants (Such as Mentor Boost, Sientra 107, or Natrelle Cohesive). The majority of our silicone breast augmentations cost 4500 for all the things you mentioned, and I'm running a special for all the mentioned things for 4000.
But this is many states away, your market could be very different.
A lot of patients goto Miami due to extremely cheap prices, same with flying to Turkey. But in those cases you don't know what kind of surgeon you're getting or what their training is. Maybe the surgeon you saw is very skilled and very busy so people are willing to pay a higher cost. Sometimes you get what you paid for with surgery. Just make sure you continue to do your research like you already are!
Hope this helps!

This is probably a very reasonable quote, but you could shop around in the area if you desire to see if you can get a better rate.

Dear Trinity1111,
the cost of surgery depends on a lot of factors (type of surgery, number of treated areas, anesthesia fee, surgeon, facility fee, city, etc.). It would be the best to visit or call plastic surgery offices and ask for a price.
