Coding 61750 vs. 61751 for a Stereotactic Biopsy

Question:

We struggle with the code description for CPT 61750 vs 61751. Our providers load MRI and/or CT scans to a stereotactic navigation machine during surgery for Stereotactic biopsy, aspiration, or excision of a tumor. Which code would be correct when an MRI scan is used during surgery? The scan was done prior to going to the OR.

Answer:

Code 61751 is reported regardless of when the CT was performed, and it is typically performed before the patient goes to the OR.
