These articles discuss what part medicare will pay for now and indicates they are adding in more codes for them.
They will at this point pay for your biological disk to be removed but not I guess the artifical implant if I understand the article correctly. The first article gives the code you need for billing.

Did your doctor's office say medicare will part for part?
Here's are some more new codes for implanting the disk. I am not sure if they have figured out what they will pay yet which might be part of the problem. It does sound like it's in the works though if they have set up codes for them.
