CPT 56625: Simple Vulvectomy for Benign or Premalignant Vulvar Disease
CPT code 56625 represents a simple vulvectomy, a gynecologic surgical procedure to remove all or part of the vulva for benign or premalignant conditions that are extensive or numerous and not amenable to local excision. This code is clinically important because it captures care for nonmalignant vulvar disease that may require definitive excision to relieve symptoms, prevent progression, or manage widespread premalignant changes. Nationally, accurate use of this code affects quality measurement, claims adjudication, and procedural utilization tracking for gynecologic surgery.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and appropriate service settings, typical payers and coverage context, and the types of benchmarks and policy issues that commonly affect reimbursement and utilization for this procedure. The publication outlines common billing considerations, frequently used modifiers (listed separately), and the clinical circumstances that distinguish a simple vulvectomy from other vulvar procedures.
This summary is intended for a national audience of payers, coding professionals, and clinical administrators seeking clear guidance on the clinical definition, service type, and sites of service associated with CPT code 56625. Data not available in the input is identified where relevant.

Billing Code Overview
CPT code 56625 describes a simple vulvectomy, a surgical procedure to remove all or part of the vulva for benign or premalignant conditions when disease is extensive or multiple and cannot be removed as a discrete local excision. The procedure encompasses excision of vulvar tissue to treat nonmalignant lesions or widespread premalignant changes.
Service Type: Surgical — Gynecologic Procedure
Typical Site of Service: Hospital outpatient department, ambulatory surgery center, or inpatient surgical setting, depending on patient condition and extent of resection.
Clinical & Coding Specifications
Clinical Context
A typical patient is a woman in her 50s–70s presenting with extensive symptomatic vulvar lesions such as widespread lichen sclerosus with scarring, multifocal high‑grade vulvar intraepithelial neoplasia, or large premalignant vulvar lesions not amenable to local excision. The clinical workflow begins with outpatient evaluation by a gynecologist or gynecologic oncologist including history, focused pelvic and vulvar exam, and biopsy of representative lesions. Preoperative workup includes medical optimization, informed consent discussing extent of resection and reconstructive options, and anesthesia evaluation. The procedure 56625 (simple vulvectomy) is performed in an ambulatory surgery center or hospital operating room under regional or general anesthesia. Intraoperative steps include marking of planned resection, excision of involved vulvar skin and subcutaneous tissue to the appropriate depth, hemostasis, and primary closure or local flap reconstruction as indicated. Postoperative care includes pain control, wound care instructions, short inpatient observation if needed, and outpatient follow‑up for pathology review and wound assessment. Common clinical scenarios include failure of conservative therapy for chronic vulvar disease, multifocal premalignant lesions where local excision is impractical, or extensive benign conditions causing functional impairment.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the vulvectomy required significantly greater effort, time, or complexity than typical, documented in operative note. |
50 | Bilateral procedure | Use if the procedure was performed on both sides of the vulva and payer requires bilateral reporting. |
52 | Reduced services | Use when the procedure was intentionally partially reduced or not completed as described. |
53 | Discontinued procedure | Use if the procedure was started but terminated for patient safety or other documented reasons. |
54 | Surgical care only | Use when only the surgeon's intraoperative services are billed separate from pre/post‑op global services. |
55 | Postoperative management only | Use when only postoperative management is billed by the surgeon. |
56 | Preoperative management only | Use when only preoperative management is billed by the surgeon prior to another provider performing the surgery. |
62 | Two surgeons | Use when two surgeons of different specialties perform distinct portions of the procedure. |
63 | Procedure performed on infants less than 4 kg | Rarely applicable; use when patient weight criteria apply (not typical for adult vulvectomy). |
66 | Surgical team | Use when a surgical team approach is required and documented. |
80 | Assistant surgeon | Use when an assistant surgeon provides assistance; bill as appropriate per payer rules. |
81 | Minimum assistant surgeon | Use when a minimal assistant is documented and allowed by payer. |
82 | Assistant surgeon (unqualified resident) | Use when an unqualified resident assists and assistant surgeon services are billed. |
TC | Technical component | Use when billing only the technical component of a service (limited applicability to procedures with separate technical components). |
