Looking for proper Medicare coding for the following complicated surgery. Please let me know if any of the anticipated codes I put below would be incorrect, bundled, need modifiers, or if there is anything else should be added or replaced with a more appropriate code.

Patient has chronic back pain, failed back syndrome and adjacent segment disease. Patient was scheduled for TLIF with exploration and also has an existing implanted intrathecal pump. Perhaps someone has access to a program that you can put in the codes and it will you. Greatly appreciate it!

2. Removal and re-implantation of spinal hardware (22852 & 22849)
