Providing Exposure More Than A Single Level Spine Procedure? What’s the Correct Code(s)?

Question:

I provide anterior exposure for a neurosurgeon colleague for an anterior spine procedure. At times, this exposure is larger to allow for a spine procedure at more than one level. The neurosurgeon’s coder indicated that I could only code co-surgeon on the primary code, 22558. Is that correct?

Answer:

CPT states that the 62 co surgery modifier is also appropriately appended to add –on codes. Therefore, as co-surgeon, if your exposure is more extensive to accommodate more than a single level anterior lumbar interbody fusion (22558), you may also report the additional levels with a 62 modifier. For example, a 2 level procedure would be reported as 22558-62 and 22585-62 for the additional level.
