This is a question which comes up alot!
For breast reduction procedures to be covered by insurance you have to fulfill certain criteria:
First you need to have symptoms related to large breasts (macromastia) such as neck pain, shoulder strap grooving, upper or lower back pain and/or rash underneath your breasts, etc.
The second criteria for most carriers is that need to fit within a sliding scale. This means that depending on your height and weight, you need to have a certain amount of breast tissue removed from each breast to qualify for insurance coverage.
For example Blue Cross uses the Schnur Sliding which I linked. Let me run through an example. Let say a woman is 5’5″ and weighs 150 lbs. Her body surface area (BSA) is 1.77. Under this Schnur scale,a surgeon would have to remove at least 425gm (about a pound) of tissue from each breast. This might be just right or too much for a woman who may otherwise qualify for a breast reduction or breast lift.
Most plastic surgeons believe that these sliding scales do not correlate with overall benefit of breast reduction surgery. It can be very frustrating to both patients and plastic surgeons because a lot more women would benefit from this surgery than the insurance companies allow.
Nonetheless, please make an appointment with a board certified plastic surgeon who can completely evaluate you before deciding the correct course.
