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
Radius, Right
The right radius forms the lateral forearm bone and, given its proximity to the wrist and elbow joints, is a frequent focus of septic arthritis extension, post-traumatic infection, or abscess following radial head or distal radius surgery. Drainage of the radius usually requires an open or percutaneous approach directly over the shaft or metaphysis, avoiding the superficial branch of the radial nerve and the radial artery during dissection. Surgeons often irrigate the medullary canal after cortical fenestration when infection has become intramedullary rather than confined to soft tissue overlying the bone. Because the forearm has limited soft tissue coverage, drainage procedures here carry a real risk of exposing tendons or neurovascular structures, which should be noted if additional protective measures were taken during the case.
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 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.
