What 49412 covers
A surgeon places interstitial devices, such as fiducial markers, in an intra-abdominal, intrapelvic, or retroperitoneal target to help guide radiation treatment. The open approach involves surgical access rather than percutaneous needle placement. This may occur during an open operation when a tumor or treatment target needs to be localized for radiation planning or delivery.
Report 49412 only as an add-on with a primary procedure; it is not a stand-alone service. The operative report should identify the target site, the devices placed, and the open approach, as well as the qualifying primary procedure performed at the encounter. CMS treats payment for this add-on within the primary procedure’s global period, so it is not paid as a separate episode outside that period.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
