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
Humeral Shaft, Left
The humeral shaft is the long tubular midsection of the upper arm bone between the surgical neck and the supracondylar region, a common site for osteomyelitis following open fracture, hematogenous seeding in children, or infected hardware after fixation. Drainage here typically involves incising the periosteum and cortex to evacuate a subperiosteal or intramedullary abscess, sometimes combined with fenestration or reaming of the medullary canal to relieve pressure and remove purulent debris. Because the radial nerve spirals along the posterior and lateral aspect of the shaft, the approach must be planned to avoid traction injury. Documentation should specify whether the procedure was purely diagnostic aspiration or a formal open incision and drainage, since this distinguishes coding to the qualifier for approach and device left behind, such as a drain.
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.
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.
