I had mine covered by insurance. It is called vein ablation, My dr said it is very common for WLS patients to get bad veins after weight loss. We have all that fat pressing on our veins and it holds them in. They pop out afterwards. I did get a DVT afterwards only small number get that 8%. I was on blood thinners for 6 months I am off of them now. I just had another follow up treatment. My legs look like a young girls.
