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
Glenoid Cavity, Right
The right glenoid cavity, the shallow socket at the lateral scapula that articulates with the humeral head to form the shoulder joint, is drained when infection or a hematoma develops within this specific bony region, often related to shoulder joint infection extending into adjacent bone, a complication of shoulder arthroplasty, or a fracture of the glenoid rim. Because the glenoid forms half of the glenohumeral joint, a collection here sits in close relationship to the joint capsule and articular cartilage, and drainage may be performed alongside joint aspiration or open arthrotomy depending on how the infection is distributed. The rotator cuff tendons and the long head of the biceps pass immediately adjacent to this area, so surgical access is planned to protect these structures. The note should distinguish glenoid bone involvement from a purely intra-articular shoulder joint collection to support accurate code selection.
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.
