Taking or letting out fluids and/or gases from a body part
Procedure Overview
Drainage procedures remove fluid or gas that has accumulated within a bursa, most often as a result of inflammation, infection, or trauma. Bursae are small fluid-filled sacs that cushion joints, and when they become irritated or infected they can swell painfully with excess fluid, a condition commonly known as bursitis. Draining the fluid relieves pressure and pain, and in infected cases removes purulent material that antibiotics alone cannot clear.
This can be done with a needle and syringe for straightforward aspiration of a swollen bursa, such as the olecranon bursa at the elbow or the prepatellar bursa at the knee, or through a small incision when the fluid is thicker or infection requires more thorough evacuation.
Drainage is typically a first-line treatment for symptomatic bursitis and is often paired with fluid analysis to identify infection, crystal disease, or bleeding as the underlying cause.
Anatomy & Axis Detail
Perineum Bursa and Ligament
The perineum's bursae and ligaments lie within a compact, highly vascular region bridging the urogenital and anal triangles, where the perineal body anchors muscles and fascia of the pelvic floor. Fluid collections here, whether from obstetric trauma, perianal or perineal abscess, infected episiotomy sites, or postsurgical seroma, tend to track along fascial planes rather than staying localized, making drainage technically demanding and important for preventing spread toward the ischiorectal fossa or deeper pelvic spaces. Because the area is close to the rectum, urethra, and external genitalia, drainage must be planned carefully to avoid injury to these structures while still achieving dependent, complete evacuation. Documentation should specify the approach used, since percutaneous needle aspiration and open incisional drainage are coded differently despite treating the same underlying collection.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
The operative or procedure note should describe fluid, pus, or blood being taken out of a bursa, with language such as aspiration, needle drainage, or incision and drainage. Coders need to confirm the target is a bursa rather than a joint space, since joint aspiration is coded to a different body system.
A common assignment error is failing to distinguish diagnostic aspiration from therapeutic drainage when both occur in the same encounter, or missing that a device such as a drain was left in place, which affects the approach and device value. Documentation should also specify whether the procedure was open or percutaneous, since this changes the approach character.
