I have a provider who performed 33223 for z45.02 on 11/26/2019 (90-day global). The same provider performed 93458-26 for I25.10 on 01/24/2019. 93458-26 is getting denied for being included in the global surgical package. Is it appropriate for me to append modifier -79 to 93458-26? I am getting mixed information when I do an online search. I found an out-of-state payer website where it said that modifier -79 may not be used for non-surgical procedures, hence I am stumped. I appreciate input from others who may have encountered a similar situation in the past. Thanks.
