What 56630 covers
A gynecologic surgeon, often a gynecologic oncologist, performs this operation to remove a portion of the vulva along with deeper underlying tissue and a surrounding margin. It is most often used to treat vulvar cancer when the planned excision is radical but does not include inguinofemoral lymph node dissection. The service is generally performed in an operating room, with the operative report documenting the anatomic extent of the vulvar excision and whether nodes were dissected.
Choose this code for a radical partial excision without lymphadenectomy; a simple partial excision is less extensive, while adding unilateral or bilateral inguinofemoral lymphadenectomy changes the code. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. For procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is not appropriate for this service. CMS may pay for an assistant at surgery; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

56630 billing questions
How does this differ from a simple partial vulvectomy?
This code represents a radical excision that includes deeper underlying tissue and surrounding tissue. A simple partial vulvectomy is less extensive.
Can this code be reported when inguinofemoral nodes are dissected?
No. Select the radical partial vulvectomy code that reflects unilateral or bilateral inguinofemoral lymphadenectomy when that dissection is performed.
Should modifier 50 be appended?
No. Modifier 50 is inappropriate for this service; use the code matching the operation and any lymphadenectomy performed.
Are related postoperative visits included?
Yes. The 90-day global period includes related postoperative care, as well as the day-before preoperative visit.
Can an assistant or co-surgeon be reported?
CMS may pay for an assistant at surgery. Co-surgeon payment requires supporting documentation, while team-surgery payment is not permitted.
