CPT 56632: Radical Vulvectomy with Bilateral Inguinofemoral Lymph Node Dissection
CPT code 56632 denotes a radical vulvectomy, a major oncologic gynecologic surgery that removes vulvar tissue adjacent to malignancy and typically includes bilateral inguinofemoral lymph node dissection. This procedure matters nationally because it addresses invasive vulvar cancers that require extensive resection and regional nodal staging or clearance, with implications for surgical morbidity, reconstruction needs, and postoperative care pathways. Payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise clinical and billing overview of CPT code 56632, including its service type and typical site of service, common payer coverage landscape, and areas where policy and billing practices affect utilization and claim adjudication. The publication summarizes benchmarks and reimbursement context where available, outlines relevant clinical context for coding and documentation, and highlights policy updates or payer-specific considerations when present. Data not available in the input will be identified as such rather than inferred.

Billing Code Overview
CPT code 56632 describes a radical vulvectomy performed for malignant disease of the vulva. The procedure involves wide excision of vulvar tissue surrounding the malignancy and commonly includes removal of bilateral inguinofemoral lymph nodes; removal of the clitoris may occur depending on disease extent. This is a radical oncologic surgical procedure aimed at local control of vulvar cancer.
Service Type: Radical oncologic gynecologic surgery
Typical Site of Service: Inpatient surgical suite or hospital operating room with possible inpatient recovery
Clinical & Coding Specifications
Clinical Context
A typical patient is a postmenopausal woman presenting with a biopsy-proven squamous cell carcinoma of the vulva with clinical or radiographic evidence suggesting regional nodal involvement. Preoperative workup includes history and physical, pelvic exam, imaging (pelvic MRI or CT, and PET/CT as indicated), and anesthesia evaluation. The multidisciplinary team (gynecologic oncology, surgical oncology, radiation oncology as needed) discusses extent of resection. On the day of surgery the patient undergoes a radical vulvectomy under general anesthesia with removal of the primary vulvar tumor and wide margins, and bilateral inguinofemoral lymphadenectomy. Intraoperative steps include tumor localization, incision and en bloc resection of involved vulvar tissue (which may include partial or complete clitoridectomy depending on tumor extent), hemostasis, bilateral groin dissection for inguinofemoral nodes, assessment for reconstruction (primary closure, skin graft, or flap), and placement of drains as needed. Postoperative care includes monitoring in PACU, wound and drain management, pain control, venous thromboembolism prophylaxis, and coordination for pathology review and adjuvant therapy planning if margins or nodes are positive. Typical site of service is an inpatient surgical setting at an acute care hospital or an ambulatory surgery center with capabilities for extended recovery if limited resection is performed and patient meets outpatient criteria.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Exempt companion code (institution-specific) | Rarely used; follow payer instructions when a CPT modifier for institutional reporting is required. |
11 | Office/Outpatient E&M primary service (contextual) | Applied when billing systems require an indicator for primary service; rare for operative codes but used per payer adjudication. |
22 | Increased procedural services | Use when work or complexity substantially greater than typical radical vulvectomy (document justification). |
50 | Bilateral procedure | Not typically appended to 56632 because procedure inherently addresses bilateral inguinofemoral nodes, but some payers may require bilateral modifier for clearly bilateral anatomic work—use payer guidance. |
51 | Multiple procedures | When additional distinct CPT procedures are performed during same operative session (e.g., separate reconstructive flap coded separately). |
52 | Reduced services | Use when procedure is begun but discontinued or performed in a reduced manner (document reason). |
54 | Surgical care only | Use when another provider bills global care and the surgeon bills only the intraoperative services. |
55 | Postoperative management only | Use when surgeon provides only postoperative care and did not perform the operation. |
62 | Two surgeons | Use when co-surgeons with distinct surgical work are required for simultaneous portions of the operation. |
66 | Surgical team (multiple surgeons) | Use for team reporting when surgical team approach is used and payer accepts team modifier. |
78 | Unplanned return to OR for related procedure during global period | Use if patient returns to OR unexpectedly for a complication related to the initial radical vulvectomy. |
79 | Unrelated procedure or service during the postoperative period | Use when an unrelated procedure is performed during the global period (not in the provided modifier list but often relevant); do not use if not present. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when APP performs assist-at-surgery services and payer requires AS. |

2080P0207X | General Surgery | May perform extensive oncologic vulvar resections and groin dissections in some centers. |
207RC0000X | Obstetrics & Gynecology | Gynecologic surgeons may perform the procedure when subspecialty care not required. |
207K00000X | Surgical Oncology | Surgical oncologists involved in multidisciplinary management and complex resections. |
363LF0000X | Plastic Surgery | Performs reconstruction (flaps, grafts) when complex closure or reconstruction is required. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
C51.1 | Malignant neoplasm of labium majus | Common primary diagnosis indicating vulvar cancer treated with radical vulvectomy. |
C51.2 | Malignant neoplasm of clitoris | Tumors involving the clitoris may necessitate partial or complete clitoridectomy as part of radical vulvectomy. |
C51.9 | Malignant neoplasm of vulva, unspecified | Used when vulvar malignancy is documented without further anatomic specificity. |
C79.82 | Secondary malignant neoplasm of genital organs | May be used when vulvar disease represents metastasis from another primary site or when regional spread is documented. |
D07.1 | Carcinoma in situ of vulva | When extensive pre-invasive disease requires radical excision in select cases or when margins are uncertain. |
