Usually weight loss surgery to remove skin that is done for cosmetic reasons is not covered by any types of health insurance and most times you'll have to pay for that out of pocket.
If the skin removal surgery is medically needed for weight loss that is affecting your health then health insurance may cover the cost of the skin removal surgery but there's no guarantee.
Skin removal surgery costs on average of $4,000.00 to $6,000.00 depending on where you're located.
