Hello. I am 5,6 and weight 199 and my bra size is 38DDD or 40 D. My insurance offer breast reduction but they require 915 grams be removed. If I get 915 grams removed, what will be my bra size!

No one can accurately predict what cup size you will be should you have your 915+ grams removed from each side. You have choices here and if you wish to go with insurance, your surgeon is obligated to remove 915 gm or more, presumably from each side and you accept the outcome regardless of what cup size you have. If you want this and do not want obligations placed on you and your surgeon, you can pursue this cosmetically and then you can dictate just how much tissue you want removed (ie: cups/fists/etc) to best attempt achievement of your goals. Your surgeons who saw you felt the insurance minimums could not easily be met so if you want control, you should consider paying for this yourself. Yes, I despite insurance companies too.

Thank you for your question! Large breasts may not only interfere with your physical ability to function in daily activities but can be emotionally burdensome as well. Although it is difficult to determine post-operative cup sizes without an in-person examination, from what you describe you are a candidate for a breast reduction. Before the procedure, I usually have my patients bring in a bra of the size they want to be post-operatively. Breast reduction surgery removes excess breast tissue and reshapes the contour of the breasts so that they are smaller and perkier. I commonly use a minimal incision technique (Le Jour), eliminating the need for large scars while providing a pleasing breast contour and shape that is proportionate to the patient’s body. Your surgeon knows exactly how much tissue he or she is taking out, because it is weighed after removal. The good news is that this procedure can be performed under local anesthesia and twilight sedation as an outpatient procedure.
Breast reduction is usually covered by insurance when the surgery is performed as part of a medically mandated procedure to treat neck, back, or shoulder pain or other problems related to the spine. Recently, managed care has adopted stricter standards for coverage, so just make sure these problems are thoroughly documented in writing by your primary care physician and plastic surgeon. They may also have to submit photographs. Even then, you may be required to seek a second opinion from a chiropractor, physical therapist, or orthopedic surgeon.
It's important to be sure expectations are realistic and you have an understanding of the commitment needed for the healing process. Make sure that you understand the nature of your surgery, the recovery process, and that you feel comfortable and emotionally ready to make these changes to your body.
I suggest you make an appointment with a board certified plastic surgeon who will examine you and go over your surgical options in detail.

Unfortunately, no one can tell you in advance exactly what size you will be after 915 grams of tissue removal. If your breasts are very dense breast tissue, this may require a smaller volume to be removed than if your breasts are mostly fat. Many insurance companies follow the medicare guidelines in which case you would only need to have 500 grams per breast removed. What is your insurance that requires such a large weight of tissue be removed?
