Can you give an example of when to report 59 Distinct Procedural Service?
On the same day a patient has a scheduled infusion in the medical oncology department, the patient is also scheduled to have a follow-up CT scan of the abdomen. Both AMA CPT® guidance and NCCI edits state that drug administration (such as IV push or infusion) that is integral to the work of the diagnostic study is not separately reportable, so the infusion services will encounter a billing edit on the same date of service as the CT scan. In this scenario, it would be appropriate to append modifier 59 (or modifier XU as applicable) to the drug administration code, since the infusion was a distinct procedural service from the CT scan.
