CPT® Code 56420

The procedure described by CPT® Code 56420 involves the incision and drainage of a Bartholin's gland abscess. Bartholin's glands are two small glands located bilaterally at the posterior introitus, which is the opening of the vagina. These glands play a role in secreting fluid that contributes to vaginal lubrication. When these glands become obstructed, fluid can accumulate, leading to the formation of an abscess, which is a localized collection of pus. The physician performs this procedure to relieve pain and discomfort associated with the abscess, as well as to prevent further complications. During the procedure, the physician uses small forceps to grasp the wall of the abscess and creates a stab incision to allow for drainage. This process not only alleviates the pressure and pain caused by the abscess but also facilitates the collection of laboratory specimens for culture, which can help identify any underlying infections. Additionally, a small balloon-tipped catheter may be inserted into the Bartholin's duct, and the balloon is inflated to maintain the patency of the duct and promote healing. The catheter is typically left in place for a duration of three to four weeks to allow for proper epithelialization of the surgically created tract, ensuring that the area heals appropriately and reducing the likelihood of recurrence.
