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
Elbow Bursa and Ligament, Left
On the left elbow, the olecranon bursa overlies the tip of the ulna and is the most frequent site of drainage in this region, typically due to repetitive pressure, direct trauma, gouty crystal deposition, or bacterial infection causing visible, often tense swelling. The elbow's collateral ligaments, which stabilize the joint against varus and valgus stress, can also accumulate fluid following sprain or degenerative change, though this is encountered less often than bursal effusion. Given the bursa's superficial position with little overlying soft tissue, aspiration is usually straightforward but carries a real risk of introducing infection if sterile technique is not maintained. Accurate documentation should note left-sided laterality and specify whether the source was the olecranon bursa or an associated ligament.
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.
Device: Drainage Device
Drainage Device denotes a device such as a tube or catheter left in place to remove fluid, blood, or air from a body part or cavity following a procedure. It is distinguished from Monitoring Device, which senses and records physiologic data rather than evacuating substances from the body.
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.
