CPT 56440 Marsupialization Reimbursement & Policy

CPT code 56440 defines marsupialization of a Bartholin's gland cyst, a minor gynecologic surgical procedure that creates a lasting drainage opening to relieve pain and prevent recurrence. The code is commonly used across outpatient settings and matters nationally because Bartholin's gland cysts are a frequent source of gynecologic visits and procedures; appropriate coding affects access to timely treatment and accurate tracking of surgical care.

This analysis covers common national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find the clinical context for the procedure, typical sites of service, and an overview of billing considerations tied to outpatient gynecologic care. The publication summarizes benchmarks where available, highlights recent policy or coverage clarifications relevant to minor gynecologic outpatient procedures, and outlines documentation elements that support appropriate reporting of CPT code 56440.

Intended for coding professionals, billing managers, and clinical leaders, the content organizes practical information on coding, common payer coverage patterns, and the clinical rationale for marsupialization, helping stakeholders align clinical documentation with billing and reimbursement practices at a national level.

Billing Code Overview

CPT code 56440 describes a surgical procedure to treat a Bartholin's gland cyst by creating a permanent opening: the provider incises the cyst and sutures its edges to adjacent tissue so the cavity remains open and continues to drain. The procedure reduces pain and lowers the risk of cyst recurrence.

Service type: Minor gynecologic surgical procedure
Typical site of service: Outpatient clinic, ambulatory surgical center, or hospital outpatient department

Clinical Context

A 28-year-old female presents to the outpatient gynecology clinic with a 5-day history of a painful, fluctuating mass at the right posterior labia majora, associated with local erythema and difficulty sitting. Physical exam demonstrates a 2–3 cm tender, fluctuant Bartholin gland cyst. The provider discusses treatment options and elects to perform a Word catheter placement or incision and drainage with marsupialization under local anesthesia in the procedure room. The clinical workflow includes pre-procedure consent and history, topical and local anesthesia administration, sterile prep, incision of the cyst, drainage of purulent material if present, and suturing the cyst edge to adjacent mucosa to create a permanent opening (marsupialization). The patient receives post-procedure instructions for wound care, pain management, and signs of infection, and a follow-up visit is arranged to evaluate healing and catheter removal if used.

`N75.1`	Bartholin's gland abscess	Infection of the gland often requires incision and drainage or marsupialization.
`N76.0`	Acute vaginitis	May coexist and require evaluation but is not the direct indication for marsupialization.
`N76.1`	Subacute and chronic vaginitis	Chronic vulvovaginal inflammation that can be associated with gland dysfunction.
`N76.2`	Other specified inflammation of vagina and vulva	Includes localized inflammatory conditions relevant to evaluation.
