CPT 56620: Simple Vulvectomy for Benign or Premalignant Vulvar Conditions
CPT code 56620 denotes a simple vulvectomy — surgical removal of all or part of the vulva for benign or premalignant conditions when lesions are extensive or numerous and not amenable to local excision. The code is important for coding and reimbursement of gynecologic surgical services that address non-malignant vulvar disease and for capturing care intensity and site-of-service planning. Nationally, accurate use of this CPT code affects surgical utilization reporting, payment parity between ASCs and hospital settings, and quality measurement for vulvar procedures.
Key payers covered in this summary include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for 56620, typical sites of service, common modifiers used with surgical CPT coding (listed elsewhere), and what to expect in payer coverage patterns. The publication outlines billing benchmarks, documentation priorities tied to clinical indications, and recent policy considerations affecting surgical coding for benign vulvar conditions. This resource is intended for clinical coders, hospital billing managers, and policy analysts seeking a clear national view of how CPT code 56620 is classified, where it is typically performed, and which major payers are relevant to reimbursement and coverage discussions.

Billing Code Overview
CPT code 56620 describes a simple vulvectomy, a surgical procedure to remove all or part of the vulva for benign or premalignant conditions when lesions are extensive or numerous and cannot be removed by local excision of a discrete lesion.
Service type: Surgical procedure — gynecologic excision
Typical site of service: Operative setting, such as an ambulatory surgery center (ASC) or hospital operating room, depending on patient complexity and anesthesia needs.
Clinical & Coding Specifications
Clinical Context
A typical patient is a woman in her 60s presenting with extensive symptomatic vulvar disease such as widespread vulvar intraepithelial neoplasia, multifocal high-grade dysplasia, or benign but diffuse conditions (eg, lichen sclerosus with superimposed hyperkeratosis) not amenable to single-lesion excision. The surgical team (gynecologic surgeon or gynecologic oncologist) evaluates the patient in clinic, documents lesion extent, discusses risks/benefits and obtains informed consent. Preoperative workup includes focused history, pelvic exam, relevant biopsies confirming premalignant or benign pathology, anesthesia evaluation, and marking the planned resection. The procedure is performed in an outpatient surgical suite or ambulatory surgery center for many patients, or in a hospital operating room when comorbidities or anesthesia needs dictate. Typical intraoperative workflow includes general or regional anesthesia, surgical removal of all or part of the vulva to achieve symptomatic control or remove extensive premalignant disease, hemostasis, and layered closure or healing by secondary intention as appropriate. Postoperative care includes pain control, wound care instructions, follow-up for pathology results, and surveillance for recurrence or complications such as infection, hematoma, urinary retention, or altered sexual function.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than usual for a simple vulvectomy (eg, extensive dissection, unexpected complexity). |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the procedure is terminated intraoperatively for reasons that do not include patient transfer of care. |
59 | Distinct procedural service | Use when a separate, distinct procedural service is performed on the same day (eg, an independent vulvar lesion excision in addition to the vulvectomy). |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the vulvectomy. |
80 | Assistant surgeon | Use when an assistant surgeon provided assistance during the vulvectomy. |
AS | Medicare beneficiary in an ASC | Use to indicate the service was performed in an ambulatory surgery center for beneficiaries eligible under Medicare. |
26 | Professional component | Use when reporting only the physician’s professional component of a global service (rare for operative codes). |
TC | Technical component | Use when reporting only the facility/technical component of a service when separated from the professional component. |
50 | Bilateral procedure | Use when the procedure is performed bilaterally and the payer requires a bilateral modifier (apply only if bilateral coding conventions apply). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207V00000X | Obstetrics & Gynecology | Most common specialty performing simple vulvectomy for benign or premalignant vulvar disease. |
| 207VG0400X | Gynecologic Oncology | Performs vulvectomies for extensive premalignant disease and complex resections. |
| 207LP2900X | Female Pelvic Medicine & Reconstructive Surgery | Manages complex vulvar reconstruction and functional concerns after resection. |
| 363A00000X | General Surgery | May perform vulvectomy in certain settings, particularly in hospitals without gynecologic specialists. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |

L90.5 | Lichen sclerosus | A chronic inflammatory dermatosis that can cause widespread vulvar changes and scarring; may lead to symptomatic disease requiring vulvectomy when extensive. |
N90.5 | Vulvar intraepithelial neoplasia, high-grade | Premalignant epithelial changes that are often treated surgically when multifocal or refractory to medical therapy. |
D07.1 | Carcinoma in situ of vulva | In situ neoplasia of the vulva; extensive or multifocal disease may require simple vulvectomy. |
L98.0 | Erythema multiforme of skin and mucous membranes (vulvar involvement) | Severe or recurrent mucocutaneous disease affecting vulvar tissue that may necessitate excision for symptomatic control. |
N90.8 | Other specified noninflammatory disorders of vulva and perineum | Category for benign but extensive vulvar conditions not classified elsewhere that can prompt vulvectomy. |
B37.3 | Candidiasis of vulva and vagina | Chronic or recalcitrant infections with resultant destructive changes can be part of the clinical picture leading to excision in select cases. |
