I do billing for five different practices across Texas and am having an issue with BCBS. They are denying most E/M codes when we use the 25-modifier (to distinguish from other services rendered the same day). I've gotten dozens of these so far. I have read some info online from different practices that BCBS is going to reduce reimbursement on E/M's when billed with the 25-modifier to 50% of the allowed amount. But I haven't seen anything in black and white from BCBS itself. Does anyone have any hard information on this change? The dozens of appeals are KILLING me. Maybe I shouldn't have taken on five practices.
