We billed a 93018 on the same day as an E/M code and I'm trying to find the rules on why we can't do this.
If all you are doing is reading the test, you don't bill for performing the test, which is what it looks like you are doing from your question.
On any test that has a technical and a professional component, if you perform the professional component only, you have to produce a report and add the modifier.
93018 is for the interpretation and report only, not for performing the test.
