Modifier -26 on labs?

I don't do laboratory coding but was shocked that a pathologist charged me for the professional component of lab tests (80053-26, 80061-26, 84439-26, 84443-26, 85025-26). As far as I am aware these codes cannot be reported with modifier -26. The person at the pathologist office told me that they CAN use mod -26 and charge me the professional fee. Someone please tell me - is this truly appropriate?
Thank you!
