Question:

Should I be putting modifier 50 on the posterior instrumentation codes like 22840 and 22842 when I place pedicle screws and rods bilaterally?

Answer:

No. The posterior instrumentation codes (22840-22844) are valued for bilateral placement, so appending modifier 50 is not necessary and also would not be accurate.
