Do you put modifier 90 (outpatient lab) on the E/M or on the ordered screening code? thx

Modifier 90 is not an E/M modifier, it is a laboratory modifier.

I have attached a great modifier resource from Novitas that may help you in the future. There are only 3 modifiers that are appended to E/M: 24, 25, 57.
