Ask Dr. Z

For complex arterial/venous interventions, sometimes we will floss the patient and externalize the wire through two access sites. For example, body flossing from the right internal jugular vein access to the right common femoral vein access for SVC stent placement. How do you code for the added effort to floss a patient? I've heard some physicians code for foreign body retrieval, but I'm not sure if that's allowable. They are treating the wire as the "foreign body" that's snared from one access through the other.
