Why doesn insurance (or Medicare) pay for astigmatism correction?
Medicare sets trends for the insurance industry. Since Medicare distinguishes between what is medically necessary and what is cosmetic, or purely optional, we are required to handle the cataract removal and the astigmatism management differently from the perspective of who pays. Medicare and private health insurance reimburse for cataract surgery. They do not pay for refractive surgery, which is necessary for astigmatism correction.
