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

Wrist Bursa and Ligament, Left

In the left wrist, the intercarpal and radiocarpal ligaments, along with small periarticular bursae, can become distended with fluid as a result of overuse injury, rheumatoid or crystalline arthritis, or infection introduced through a puncture wound or spreading tenosynovitis. The wrist's tightly packed anatomy, where ligaments run close to the carpal tunnel's contents and extensor or flexor tendon sheaths, makes accurate needle or incisional placement important to avoid nerve or tendon injury during drainage. Collections are often small and may require image guidance to localize precisely. Documentation should record left-sided laterality and identify which specific ligament or bursa was drained, since this distinguishes the procedure from drainage of an adjacent tendon sheath or the wrist joint capsule itself.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Qualifier: Diagnostic

Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.

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.

Commonly Confused With

ExtirpationDrainage is frequently confused with Extirpation, which removes solid matter such as a calcified deposit or loose body rather than fluid.
ExcisionIt is also distinct from Excision, where a piece of the bursa wall itself is cut out, sometimes performed alongside drainage when a chronically inflamed bursa is removed rather than simply emptied.
