About 38792: Radioactive tracer injection for sentinel node
Reports radioactive tracer injection to localize sentinel lymph nodes, commonly before breast cancer or melanoma surgery and subsequent node removal.
This service is the injection of radioactive tracer to help locate sentinel lymph nodes that drain a tumor site. It is commonly used in breast cancer and melanoma care before sentinel node biopsy or excision. A nuclear medicine or radiology clinician, or the surgeon, may perform the injection in a facility or office setting. The injection is distinct from imaging that follows it and from surgical removal of the node.
Report 38792 when the documented service is the radioactive tracer injection for sentinel node localization. The record should identify the injection site, laterality, tracer, and clinical purpose; report a separately performed node biopsy or imaging service with its applicable code. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 applies to bilateral performance and is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

38792 billing questions
How is 38792 different from sentinel node removal?
38792 reports the radioactive tracer injection used to locate the node. Report the appropriate biopsy or excision code separately when the surgeon removes a node.
Does this code report lymphoscintigraphy imaging?
No. It reports the injection procedure; lymphatic and node imaging is a separate service, such as 78195 when performed and supported.
Can 38792 be reported with nonradioactive sentinel node mapping?
It may be reported with 38900 when both radioactive tracer injection and the separately documented nonradioactive intraoperative mapping technique are performed.
When is modifier 50 appropriate?
Use modifier 50 when the injection service is performed bilaterally. CMS pays the bilateral procedure at 150%.
What documentation supports reporting 38792?
Document the tracer injection, injection site and side, and its purpose in localizing sentinel nodes. Identify any separately performed imaging or node excision in the record.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
