I work for a hospital that we have several physicians in same practice that may see the same patient for for different reasons in same day. EX: Pt comes into ER and one of our docs see them for critical care and an hr later another one of our docs are putting in ET tube or CVC line (or both). When I bill I will use 99291 for the 1st physician and give the other doc the ET tube/CVC line. The insurance company is saying same group/specialty won't get paid. Should I be putting modifier 25 on 99291 claim??? I didn't think you would because it is different physicians. HELP!!!
