I am 26 years old and am having surgery on January 21, 2009. I have a "bad" disc at L4-5 that is just getting worse and will not get any better. I have had this pain off and on for my whole life but over the past 3 years it has become constant and there is no way I can continue to live like this. I have been through physical therapy, chiropractic, massage therapy, and nothing has worked so surgery is now the next step. My doctor thinks I am a very good candidate for the disc replacement becuase of my age. Has anyone else had this surgery and if so did you have a battle with your health insurance. My spine surgeon said that a lot of insurance companies do not approve the disc replacement surgery and they are calling today to find out if my health insurance will cover it. If they do not then I am going to have to have a fusion done. Any input?
