The cost of an aesthetic procedure can vary greatly depending upon several factors, including the type of procedure you are having, the associated costs (i.e. same day surgery vs. an overnight hospital stay), and physician fees.
When the surgery is being performed to improve physical appearance only, it is usually not a covered service by most insurance plans. If the surgery is more reconstructive in nature, however, and is necessary to improve the function of a body part, it may be covered. Since insurance coverage varies, you will need to check with your own plan for specifics.
