CPT code 56630: Vulvectomy, partial, without lymphadenectomy2026 Medicare rate & RVUs

Medicare pays $897.82 for 56630 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
