If the excess eyelid skin is pushing down your eyelids and your vision is impaired, then insurance may help cover the costs.
The definitive test required by the insurance companies is the visual field exam - taped and untaped. You'll look at some flashing lights and push a button when you see the light. Then you'll repeat the test after having your eyelids taped up. The computer records how many you saw and how many you missed. It also keeps track of false positives and negatives, so it doesn't help to cheat.
If the test shows that your vision in the upper fields have improved by have your eyelid skin removed from your field of view, then insurance will likely cover it. Unless it's medicare, they may also require preop photos and a letter of medical necessity submitted to them for prior authorization before surgery.
Of course, all of this depends on your insurance coverage. Contact your insurance company to make sure that its not excluded from your policy. The procedure code is 15823. If it is covered, you'll still be responsible for meeting your deductible and co-pays, based on your coverage.
