I work in our software system administration, I am not a daily coder, nor am I a biller...I have recently been brought into discussions about ways to make the billing process easier in our software system but I am concerned with what I am being told by the billing staff...they are telling me that they have created these 'standard practices' of their own to add a modifier 25 to any office visit when specific codes like UAs-81003, Injections-J Codes and Admin codes are on an encounter for specific payers. And in some cases, with some payers they are adding a modifier 25 to the office visit when any other service at all is on that encounter. When I asked about this practice, they tell me "It is the payer's policy" that they will only pay when the modifier 25 is attached, but when I have asked other health centers, I am told that they don't have these issues with these particular payers in most cases. There are a few exceptions. I have brought this concern up to the staff in the billing office and their managers, but it does not appear that anything has changed, they still stand by their "payer policy". Anybody else experience these kinds of denials/issues due to payer policy?
