CPT 56630: Radical Vulvectomy for Malignant Disease
CPT code 56630 denotes a radical vulvectomy, a major oncologic surgical procedure to remove all or part of the vulva for malignant disease. The code captures comprehensive resection often including adjacent tissues and, when indicated by disease spread, removal of the clitoris and regional lymph nodes. This procedure is clinically significant given its role in definitive surgical management of vulvar cancer and its implications for inpatient surgical resources, perioperative care, and multidisciplinary oncology coordination.
Key payers addressed in this national review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for 56630, typical settings of care, and how the code is used in surgical oncology documentation. The publication highlights benchmarks and billing practice observations, common modifier usage when available, and relevant policy considerations that affect coverage and claims processing for major gynecologic oncologic procedures.
This summary provides clinicians, coding professionals, and payers with an overview of the code’s clinical intent, typical utilization settings, and points of attention for billing and reimbursement workflows. Data not available in the input is explicitly omitted from this summary.

Billing Code Overview
CPT code 56630 describes a radical vulvectomy, a surgical procedure that removes all or part of the vulva to treat malignant disease. The operation may include excision of adjacent tissue and, depending on disease extent, removal of the clitoris and regional lymph nodes. As a radical procedure, tissue beyond the visible tumor is commonly resected to achieve oncologic margins.
Service type: Major surgical oncology procedure
Typical site of service: Inpatient surgical suite or hospital operating room, with postoperative care in a hospital or specialized surgical recovery unit.
Clinical & Coding Specifications
Clinical Context
A 62-year-old female presents with a biopsy-confirmed squamous cell carcinoma of the vulva involving the labia majora and periclitoral tissue with concern for deep stromal invasion. After multidisciplinary tumor board review, the patient is scheduled for a 56630 radical vulvectomy under general anesthesia for oncologic resection. Preoperative workup includes pelvic exam, imaging (pelvic MRI or CT), routine labs, and discussion of potential lymph node assessment (separate procedures) and reconstructive options.
The clinical workflow: preoperative evaluation and consent in the gynecologic oncology clinic; operating room for radical excision of vulvar tissue with appropriate margins, possible partial clitoridectomy based on tumor extent, hemostasis and specimen orientation for pathology; immediate wound management which may include primary closure, local flap reconstruction, or delayed closure; postoperative recovery in PACU with inpatient admission for pain control, wound care, and physical therapy as indicated; pathology reporting to guide adjuvant therapy decisions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for 56630 and supported by operative report. |
23 | Unusual anesthesia | Use when a procedure is performed under general anesthesia specifically because of an unusual circumstance (not commonly used; document reason). |
26 | Professional component | Use when billing is separated into professional and technical components for services that allow split billing (rare for this surgical code). |
50 | Bilateral procedure | Use if bilateral anatomic involvement is reported and payer requires a bilateral modifier for bilateral vulvar procedures. |
51 | Multiple procedures | Use when 56630 is reported with additional distinct surgical procedures during the same operative session. |
52 | Reduced services | Use when the procedure is intentionally partially reduced or not completed per documented reason. |
53 | Discontinued procedure | Use when 56630 is started but discontinued due to extenuating circumstances; document reason. |
54 | Surgical care only | Use when only the surgical component is billed and other global components are billed separately. |
55 | Postoperative management only | Use when only post-op care is billed by a surgeon who did not perform the operation. |
62 | Two surgeons | Use when two surgeons of different specialties work together as primary surgeons performing distinct portions of 56630. |
63 | Procedure performed on infants/neonates | Not commonly used for this code; included for completeness when applicable. |
76 | Repeat procedure by same physician | Use when 56630 is repeated later by the same physician for the same patient. |
78 | Return to OR for related procedure during postoperative period | Use when patient returns to OR for a related complication of the original 56630. |
79 | Unrelated procedure or service by same physician during postoperative period | Use when an unrelated procedure is performed during global period. |
RT | Right side | Use to identify laterality when payer requires laterality reporting for component procedures. |

207VG0400X | Gynecologic Oncology | Gynecologic oncologists typically perform radical vulvectomies and manage perioperative oncology care. |
207P00000X | Surgery | General surgeons may be involved when extensive resections or flap reconstructions are required. |
