My BMI is 36. Are there any surgeons that would schedule me in for a tummy tuck?

An in -person consultation is always best for a proper exam and evaluation, consult carefully with a board certified PS.

The reason that many plastic surgeons are reluctant to perform an abdominoplasty with fat transfer to the behind for patients with a BMI higher than 30 is that we understand that the risks of complications can be much higher than would be considered safe. Caution is a good thing. I'm sure that you can find someone to do your surgery independent of a high BMI, but would you want to? Sometimes I encounter patients who want procedures that I feel are poorly advised in their situation. Sometimes, I simply refuse. Sometimes, I ask "If I can't do what you want, what can I do to help you?". Wisdom and experience are good traits for a plastic surgeon. Consider what your plastic surgeon suggested, sounds like decent advice.

A TT is certainly doable at a BMI of 36. At a BMI of 40, my anesthetist will not put you to sleep because of the increased anesthetic risk. It's really an anesthetic problem according to the criteria in your area. 
I suggest seeking another another opinion from a plastic surgeon certified by the American Board of if you lose the weight after the TT, you may have sagging skin again, so it is best to lose the weight before the surgery.Regarding losing more weight, 
Thank you for your question, and good luck.

Pictures might help and generally, I dont use a high BMI as a no go. Losing the weight might result in less fat to do the Brazilian.Good luck and pick a board certified plastic surgeon.

Most plastic surgeons suggest that you finish having
children, get your weight within 10 pounds of your ideal weight and have a BMI
less than 30 before undergoing an abdominoplasty with repair of the stretched
out abdominal muscles and liposuction of selective areas, in order to achieve
the best long term cosmetic result with the least potential complications.
 
 Following the advice
of anyone who would presume to tell you what to do without seeing photos and
more importantly without taking a full medical history, examining you, feeling
and assessing your tissue tone, discussing your desired outcome and fully
informing you about the pros and cons of each option would not be in your best
interest. Find a plastic surgeon that you are comfortable with and one that you
trust and listen to his or her advice. The surgeon should be certified by the
American Board of Plastic Surgery and ideally a member of the American Society
for Aesthetic Plastic Surgery (ASAPS). You should discuss your concerns with
that surgeon in person.

With a BMI over 30 your risks of wound healing and post operative problems will increase. You may not be a candidate for a tummy tuck at this time but you may be a candidate for a panniculectomy ( removal of extra skin of the lower abdomen) and some liposuction and a tummy truck ( tightening of the muscles and removal of more skin) in the future. You may want to explore that option of a staged procedure.
