Re: Info on ALIF surgery ???
I cannot respond to your question specifically but I can give you a bit of general information.
Insurance companies have tightened their criteria for a fusion, be it ALIF, PLIF, TLIF, AxiaLIF....beginning about two years ago. I was scheduled to have a 3 level PLIF a year ago...March 2nd was the date. I got within a day of surgery before finding out it was not approved. I will spare you all the details....The appeal was a complex procedure, and it was during this time that I learned about the criteria that many of the big insurance companies are now using to evaluate a need for spine surgery.
During the course of this experience, my surgeon told me that in 22 years of doing spine surgery, he could count the number of his patients who would have met these new criteria. He was so incensed that the insurance company was telling him what he could and couldn't do and what was best for his patient, without ever laying eyes on me or my MRIs!
My guess just from the few words you used to describe your condition is that you meet the criteria for a discectomy, but not for a fusion. They are figuring that the discectomy, which is a less complicated procedure, requiring a shorter hospital stay, etc., will resolve your issues and save them some money. They are betting on that being the case, because if it doesn't work, you will then be needing the larger, more complex surgery.
Your doctor may be able to explain to their satisfaction that there are reasons why you require the fusion, in which case, they will approve the operation.
My appeal was successful and I had a 3 level fusion on June 1st.
Hope this helps you understand what might have happened in your case....
