What 38780 covers
Code 38780 represents an extensive transabdominal operation to remove lymphatic tissue across the retroperitoneum, reaching pelvic, aortic, and renal nodal fields rather than a limited regional basin. Urologists and surgical oncologists commonly perform it for selected cancers requiring broad retroperitoneal clearance, including testicular malignancy; the operative report should establish the extent and nodal territories treated.
Report 38780 when the surgeon performs that extensive dissection, not for isolated sampling or a more confined pelvic or abdominal nodal clearance. Document the indication, approach, and nodal boundaries, and distinguish the work from other procedures performed in the same session. Medicare treats it as major surgery: the day-before preoperative visit and related care through 90 days after surgery are included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures receive the standard reduction. Modifier 50 is inappropriate. An assistant may be paid; co-surgeons require supporting documentation, while team surgery is not permitted.

- 38770Pelvic lymphadenectomyExternal iliac, hypogastric, obturator
- 38770 is directed to pelvic nodal groups. It does not describe the broader retroperitoneal dissection represented by 38780.

38780 billing questions
How is 38780 distinguished from 38747?
Use 38780 for broad retroperitoneal clearance reaching pelvic, aortic, and renal nodal fields. Code 38747 describes regional abdominal node removal rather than this extensive dissection.
Can modifier 50 be appended for bilateral work?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
What postoperative care is included?
The major-surgery global period includes the day-before preoperative visit and related postoperative care for 90 days.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What documentation supports choosing 38780?
The operative report should identify the extensive retroperitoneal dissection and the nodal territories addressed, including whether pelvic, aortic, and renal fields were treated.
