Gynecologic surgery
About 56640: Complete radical vulvectomy with pelvic node dissection
Reports complete radical removal of the vulva with bilateral inguinofemoral and pelvic lymph node dissection, typically for invasive vulvar malignancy.
This operation removes the vulva in its entirety as a radical cancer procedure and includes bilateral inguinofemoral lymphadenectomy and pelvic lymph node dissection. It is generally performed by a gynecologic oncologist in a hospital or other surgical facility for selected patients with invasive vulvar cancer when the operative plan includes this extent of nodal surgery. The groin and pelvic node work is part of the service represented by this code.
Select this code when the operative report supports complete radical vulvar removal and both the bilateral inguinofemoral and pelvic node dissections; a partial resection or a procedure without pelvic node dissection points to a different code in the family. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. A qualifying bilateral service reported with modifier 50 is paid at 150%. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

56640 billing questions
How does 56640 differ from 56637?
56640 includes pelvic lymph node dissection in addition to complete radical vulvectomy and bilateral inguinofemoral lymphadenectomy. Use 56637 when the operative service includes the bilateral groin node dissection but not pelvic node dissection.
Are the groin and pelvic node dissections separately reported?
They are included in 56640 when performed as part of the coded operation. The operative report should document the extent and laterality of the node dissections.
When should 56633 be used instead?
56633 describes complete radical vulvectomy without the inguinofemoral lymphadenectomy included in 56640. The documented operation, rather than the cancer diagnosis alone, determines the appropriate code.
What documentation supports 56640?
Document that the vulvar removal was complete and radical, and describe bilateral inguinofemoral and pelvic lymph node dissection. Include the operative findings and the extent of each surgical component.
How does Medicare handle other procedures performed in the same session?
Under the listed multiple-procedure rule, Medicare pays the highest-valued procedure in full and other procedures at 50%. Related postoperative care for 56640 falls within its 90-day global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
