Billing Code Overview

CPT code 56405 describes the incision and drainage of an abscess in the genital area of a female patient. This procedure involves making an incision to evacuate pus and relieve pain and infection.

Service type: Minor surgical procedure (incision and drainage)
Typical site of service: Ambulatory surgical center, hospital outpatient department, urgent care, or office-based procedure room

Clinical Context

A 28-year-old female presents to an outpatient clinic with a 3-day history of a painful, fluctuant swelling in the left vulvar vestibule with surrounding erythema, warmth, and purulent drainage. She reports localized sharp pain with sitting and dyspareunia. On exam the provider identifies a 2.5 cm abscess in the labia minora consistent with a Bartholin gland abscess. After obtaining informed consent and confirming no contraindications, the provider performs an incision and drainage of the abscess under local anesthesia, evacuates purulent material, irrigates the cavity, and may place a small packing or Word catheter per clinical judgment. Specimens for Gram stain and culture may be collected if infection appears severe or recurrent. Post-procedure care includes wound instructions, analgesia, possible oral antibiotics based on clinical risk, and follow-up within 48–72 hours to reassess healing and remove packing if present.
