Exam, Modifier -25 and Diagnostic Tests
Question: If I am performing multiple diagnostic tests, do I need to append modifier -25 to the exam?
Answer: Modifier -25 indicates a separately identifiable exam when performing a procedure. It’s not appropriate to append to the exam when billing testing services. Best to check the Medicare National Correct Coding Initiative (CCI) edits to confirm the bundling of all tests before submitting the claim.
