What 00906 covers
00906 covers anesthesia for surgery that removes part or all of the vulva, commonly to treat a vulvar lesion or malignancy. A gynecologic surgeon typically performs the operation in an operating room; the anesthesiologist or CRNA reports the anesthesia service, separately from the surgeon’s procedure.
Choose 00906 for a vulvectomy rather than an operation on the vagina, anorectal region, or another perineal site. The operative report should identify the vulvar resection and its extent, and document any accompanying groin-node or adjacent-tissue work; the anesthesia record should support the anesthetic service and its timing. The code has 4 base units, and Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. CMS counts anesthesia time in minutes from preparation for anesthesia until the practitioner is no longer personally attending and the patient can safely be placed under postoperative care, converting minutes to 15-minute units to one decimal place; the conversion factor varies by locality.

00906 billing questions
When should I choose 00906 instead of 00904?
Use 00906 when the operation is a vulvectomy. Code 00904 is for a radical perineal procedure other than a vulvectomy.
Is the vulvectomy itself reported with 00906?
The surgeon reports the vulvectomy procedure, while the anesthesia practitioner reports 00906 for the anesthesia service. The operative record should support the surgical service, and the anesthesia record should support the anesthesia service.
How are anesthesia time units calculated for 00906?
CMS counts anesthesia time in minutes and converts it to units of 15 minutes, calculated to one decimal place. The count begins when the practitioner starts preparing the patient for anesthesia and ends when personal attendance ends and the patient can safely be placed under postoperative care.
What documentation supports reporting 00906?
The operative report should identify the vulvectomy and describe its extent, including any accompanying groin-node or adjacent-tissue work. The anesthesia record should support the service and the start and end of anesthesia time.
