Gynecologic oncology surgery
About 56637: Complete radical vulvectomy with bilateral groin node removal
Reports complete radical removal of the vulva with lymph node dissection in both groins, typically for vulvar cancer requiring this extent of surgery.
A gynecologic oncologist typically performs this operation in a hospital operating room for vulvar malignancy requiring complete radical excision and bilateral inguinofemoral lymph node dissection. The procedure includes removal of the vulvar tissue and the specified groin node work on both sides; it is more extensive than a complete vulvectomy without lymphadenectomy or a partial radical excision.
Choose the code from the operative extent, not the diagnosis alone. The operative report should establish complete radical vulvar excision and lymph node dissection on both sides. The bilateral work is represented in the code, so modifier 50 is inappropriate. 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 the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment may be available, and co-surgeons are permitted; team surgery is not permitted.

56637 billing questions
How does this differ from code 56634?
This code represents complete radical vulvar excision with lymph node dissection on both sides. Code 56634 describes the corresponding complete radical operation with unilateral inguinofemoral lymphadenectomy.
Should modifier 50 be added?
No. The code already represents bilateral groin node dissection, and CMS identifies modifier 50 as inappropriate for this service.
Are the groin node dissections separately reported?
The bilateral inguinofemoral lymphadenectomy is included in this code. The operative documentation should support node dissection on both sides.
What documentation supports choosing this code?
The operative report should describe complete radical excision of the vulva and lymph node dissection in both groins. A cancer diagnosis by itself does not establish the operative extent.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available, and co-surgeons are permitted under the CMS facts for this code. Team surgery is not permitted.
