My question relates to appending modifier -59 to multiple units. CPT® codes 97150 and 97113 X 4 have been charged, and I believe the requirements for the modifier have been met. That is, we should append modifier -59 to each unit of 97113 (i.e., apply -59 four times). Is that correct?
Yes, assuming the criteria for modifier 59 are met, you may append to all four 97113 codes as it is the column 2 code (mutually exclusive) in the national correct coding initiative (CCI) edits.
