Studies analyzed 625,316 surgical procedures and found that claims with modifier 22 had higher charges, payments, but were more likely to be denied. Overall mean payments varied, with some procedures showing higher payments with modifier 22. However, for most surgeries, little financial advantage was seen, suggesting surgeons have little incentive to use modifier 22 under the current system.
