About 56631: Radical partial vulvectomy with unilateral node dissection
Reports radical partial removal of the vulva together with inguinofemoral lymph node dissection on one side, typically for vulvar malignancy.
This operation removes part of the vulva through a radical oncologic excision and includes dissection of inguinofemoral lymph nodes on one side. Gynecologic oncologists typically perform it in an operating room for vulvar cancer when nodal surgery is part of the same operation. The code distinguishes partial vulvar removal from complete removal and specifies unilateral node dissection.
Select this code when the operative report supports both the radical partial excision and the one-sided inguinofemoral dissection; the included node procedure is not separately reported as an additional service. The descriptor is unilateral, so do not append modifier 50. CMS 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% reduction. Assistant-at-surgery and co-surgeon payment may be made; team surgery is not permitted.

56631 billing questions
How does this differ from 56630?
56630 describes radical partial vulvar removal without the inguinofemoral lymph node dissection included in 56631. Use 56631 when the same operation includes unilateral node dissection.
Can the lymph node dissection be reported separately?
The unilateral inguinofemoral dissection is included in 56631. Do not separately report that same dissection as an additional service.
Should modifier 50 be used?
No. This code describes a unilateral operation, and modifier 50 is not appropriate.
What documentation supports the code?
The operative report should establish radical partial removal of the vulva and inguinofemoral node dissection on one side. It should also identify whether the vulvar removal was partial or complete.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
