Is modifier 50 used in nerve block family of codes 64400-64484?
For example let narrow it down to the codes 64479-64484. If a 64483(single level) was done. Any addt'l levels would be coded with 64484. Based on that, the provider would not bill with 50 modifier. Let me know if you can think of when modifer 50 would be used with nerve block codes.

If the procedure was done bilaterally, you would use modifier 50 with 64483, or list it twice with RT and LT. The additional levels (64484) is used when the injection moves. Example L2/L3 - 64483 then L3/L4 would be 64484, and you would use modifier 50 if they were done bilaterally.
