Modifier

I am trying to bill CPT 74000 and 74250. I have a rejection for them but I noticed on CMS website a modifier can be used. Could you tell me which one?

modifier?

What is the reason for the rejection? Is it diagnosis related?

Are you performing both the technical and professional component of the test?

We need more information to help.
