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
Finger Phalanx, Left
On the left hand, drainage of a finger phalanx treats bony infection that has developed within one of the small segments of a digit, frequently following a puncture wound, bite, or an untreated paronychia that has tracked to bone. The proximal and middle phalanges have more soft tissue coverage than the distal phalanx, so the surgical approach and extent of debridement vary depending on which segment is affected and its proximity to the interphalangeal joints. The surgeon incises over the infected area, evacuates the abscess, and removes devitalized bone while sparing the flexor tendon sheath and digital neurovascular bundles wherever possible. Because finger infections can rapidly compromise joint motion, the specific phalanx and digit drained should be clearly recorded.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
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.
