A breast lift is a cosmetic operation and is not covered by insurance. A breast reduction which includes a breast lift in addition to reduction of the way to the breast sometimes is.
You insurance is a contract between you and your insurance company. Given the variety of options for insurance, there are wide variations in benefits. However, your company should be able to answer your question about your coverage. In my experience, breast lifts are never a covered procedure, while breast reduction may be covered from time to time. Your insurance company will also guide you to surgeons who accept their plan as payment. Hope this helps you get relief.
