Taking or letting out fluids and/or gases from a body part

Procedure Overview

Drainage procedures on the upper bones remove fluid or gas, most often pus from an infected area, through incision, needle aspiration, or placement of a drain. This applies to bones such as the sternum, ribs, clavicle, scapula, humerus, and the bones of the forearm and hand when an abscess forms within or around the bone, commonly as a result of osteomyelitis or a post-surgical infection at a sternotomy or fracture site.

The goal is to relieve pressure, reduce bacterial load, and allow antibiotics to work more effectively, sometimes as an urgent measure to prevent the infection from spreading into the bloodstream or an adjacent joint. A drain may be left in place temporarily so fluid continues to exit as the area heals.

Anatomy & Axis Detail

Ribs, 1 to 2

Ribs 1 and 2, the uppermost and most protected pair of the thoracic cage, sit close to the subclavian vessels, brachial plexus, and lung apex, so a collection requiring drainage in this location - whether from osteomyelitis, a post-traumatic hematoma, or a spreading chest wall abscess - demands careful attention to these adjacent structures. Their shortened, curved shape and deep position beneath the clavicle and shoulder girdle musculature make surgical access more limited than for lower ribs, often requiring a targeted approach guided by imaging. Coders should note that this code applies specifically when the first or second rib, or both together, is the site drained; involvement of additional lower ribs would shift the procedure to a different rib grouping. The clinical note should specify the fluid character and whether a drain or catheter was left in place following evacuation.

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 record should clearly state that fluid, typically purulent material, was taken out of the bone or the space immediately surrounding it, and whether a drainage device was left in place, since that affects the diagnosis qualifier used. The specific bone and any device left behind both need to be documented precisely.

A common assignment mistake is applying Drainage when the surgeon actually removed dead or infected bone tissue, which would fall under Excision or Extirpation depending on whether solid fragments were taken out. Coders should also watch for cases where drainage is incidental to a larger debridement procedure performed at the same operative session, which may require a separate code.

Commonly Confused With

ExtirpationExtirpation is easily confused with Drainage because both can be performed for infection, but Extirpation removes solid matter such as a bone sequestrum or thick abscess debris, while Drainage removes liquid or gas.
ExcisionExcision is distinct because it involves cutting out actual bone tissue rather than evacuating fluid.
