It depends on the internal policy and edits of the plan you work for. Christine has good advice above. When talking about the provider side, they would probably say does it "hurt" anything to "accidentally" apply a 25 modifier when nothing else was billed on that claim/date that would require it? Probably not. However, from a payer and auditing/coding standpoint, it is a red flag that the provider is just automatically appending a 25 to everything to bypass any and all edits. In my view, it should be denied. It is being appended incorrectly when NCCI does not call for it. If there is nothing else performed or billed on that date which would require a 25 they are using it incorrectly and that is an error. These providers that have use of the 25 modifier that is not in line with other providers in the geographic area and specialty are red flags. Same with 59.
