CPT 00906: Anesthesia for Vulvectomy
CPT code 00906 covers anesthesia services for vulvectomy, a surgical excision of external female genitalia. This code identifies professional anesthesia time and complexity associated with gynecologic procedures involving the vulva, and it matters nationally because accurate coding supports appropriate clinical documentation, billing consistency, and payment for perioperative anesthesia services across ambulatory surgical centers and hospital operating rooms. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise explanation of the clinical service represented by the code, common payer coverage considerations, and context for how this anesthesia code relates to related genital and perineal anesthesia codes. The publication summarizes typical sites of service, core billing themes, and how 00906 is positioned among nearby anesthesia codes for genital and perineal procedures. Data not available in the input is noted where applicable. This overview is intended for clinicians, billing professionals, and policy analysts seeking a national-level snapshot of the code’s clinical scope and payer landscape.

Billing Code Overview
CPT code 00906 describes anesthesia services provided for a patient undergoing vulvectomy, defined as excision of the external female genitalia. The service type is anesthesia for a surgical gynecologic procedure. The typical site of service is an operating room or other inpatient/outpatient surgical setting where vulvectomy procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 52-year-old female with chronic vulvar dysplasia and recurrent vulvar carcinoma is scheduled for a partial vulvectomy (excision of the external female genitalia) under general anesthesia with possible local/regional blocks for postoperative analgesia. Preoperative evaluation by the anesthesia team includes review of oncologic history, prior surgeries, airway assessment, medication reconciliation, and evaluation of comorbidities (hypertension, diabetes). The patient arrives to an outpatient ambulatory surgery center or hospital operating room — typical sites of service include the main OR in a hospital or an ambulatory surgery center equipped for gynecologic oncology procedures. On the day of surgery, consent for anesthesia is obtained; monitoring per ASA standards is applied. Induction of general anesthesia is performed with endotracheal intubation or laryngeal mask airway based on airway assessment and planned surgical exposure. Regional techniques such as pudendal nerve block or local infiltration may be performed intraoperatively for analgesia. Intraoperative management addresses hemodynamics, blood loss, temperature, and positioning for perineal access. If intraoperative findings require extension to radical perineal resection, anesthetic plan is adjusted for longer duration. Post-anesthesia care includes pain control, nausea prophylaxis, monitoring of voiding, and instructions for wound care prior to discharge or transfer to an inpatient unit if indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia involves substantially greater work, complexity, or time than typical for the vulvectomy procedure and payer allows modifier 22 on anesthesia claims per policy. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary but not typically required for the procedure (e.g., patient refusal of sedation or extreme anxiety). |
50 | Bilateral procedure | Use when bilateral vulvar procedures are performed and payers require bilateral modifier reporting. |
52 | Reduced services | Use when the planned vulvectomy is partially performed or curtailed, resulting in reduced anesthesia services. |
53 | Discontinued procedure | Use when the procedure is started but halted for patient safety and anesthesia services are terminated accordingly. |
54 | Surgical care only | Use when reporting only the surgical portion and another practitioner reports the anesthesia; typically not appended to anesthesia codes but relevant in team contexts. |
55 | Postoperative management only | Use when reporting only postoperative care responsibilities when anesthesia responsibility is transferred. |
62 | Two surgeons | Use when two surgeons are required concurrently for a complex vulvectomy and payer guidance affects anesthesia billing. |
78 | Return to the operating room for a related procedure during the postoperative period | Use when the patient returns to OR for a complication related to the initial vulvectomy requiring additional anesthesia. |
AA | Anesthesia service performed personally by anesthesiologist | Use to indicate the physician anesthesiologist personally performed the anesthesia service. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | Use when the anesthesiologist supervises multiple concurrent CRNA cases per payer rules. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for anesthesia | Use when a qualified non-anesthesiologist advanced practitioner provides anesthesia services as recognized by the payer. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures where the anesthesiologist performed more than half of the qualifying activities | Use to report physician medical direction for multiple concurrent anesthesia cases including this procedure. |
QS | Monitored anesthesia care (MAC) service | Use when the service provided is monitored anesthesia care rather than general anesthesia for vulvar procedures. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physician anesthesiologists who direct or personally provide anesthesia for vulvectomy. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who may administer anesthesia under supervision or independently per state and payer rules. |
207LA0401X | Pain Medicine (Anesthesiology) | Anesthesiologists with pain subspecialty who may provide perioperative nerve blocks or complex analgesic management. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
N50.9 | Disorder of male genital organs, unspecified | Present in raw data but not anatomically aligned with vulvectomy; included in input lists and may represent coding cross-reference errors or concurrent male genital diagnoses in other patients. |
N76.89 | Other specified inflammation of vagina and vulva | Directly relevant as severe vulvar/vaginal inflammation can lead to excisional procedures such as vulvectomy for refractory disease. |
R10.2 | Pelvic and perineal pain | Symptom that may prompt evaluation leading to surgical intervention including vulvectomy for pain refractory to medical therapy. |
N47.1 | Phimosis | A male genital diagnosis included in the input; not directly relevant to female vulvectomy but present in the provided list. |
N48.1 | Balanitis | Another male genital diagnosis from the provided list; not directly related to vulvectomy but included per input. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
00902 | Anesthesia for procedures on male genitalia | Related by anatomical site coding conventions; used for male genital procedures and contrasted with vulvectomy anesthesia coding. |
00904 | Anesthesia for procedures on the perineum | Overlaps anatomically; used when the procedure focus is perineal rather than exclusively vulvar and for coding decisions between perineal vs vulvar codes. |
00908 | Anesthesia for radical perineal procedures | Used when the vulvectomy extends to a radical perineal resection; indicates more extensive surgical field and typically longer anesthesia time. |
01992 | Anesthesia for diagnostic or therapeutic nerve blocks | Used when intraoperative or perioperative pudendal or other nerve blocks are performed for analgesia in conjunction with vulvectomy. |
