Dr. Pan completed a complete radical vulvectomy with bilateral inguinofemoral lymphadenectomy. The appropriate code to report this procedure is ____.

The procedure described, a complete radical vulvectomy with bilateral inguinofemoral lymphadenectomy, is accurately represented by the code 56637.

This specific code captures the complexity and extent of the surgical intervention. A radical vulvectomy involves the removal of the vulva and may also necessitate the resection of surrounding structures, which is a significant surgical procedure. The addition of bilateral inguinofemoral lymphadenectomy indicates that lymph nodes in both the inguinal and femoral regions are also being removed, reflecting a more extensive surgical approach due to potential cancer involvement.

The distinction in the coding options typically relates to the complexity, extent, and specific anatomical areas involved. Other codes in the list may correspond to different surgical levels or combinations, but only 56637 explicitly covers the full scope of a complete radical vulvectomy along with the associated lymphadenectomy at the specified levels needed for accurate coding in this scenario.
