Operation Definition

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

Procedure Overview

Drainage procedures on the lower bones remove fluid or gas that has built up within or around a bone, most often pus from an infection such as osteomyelitis or a subperiosteal abscess. A surgeon opens a channel into the affected area of the pelvis, femur, tibia, or another lower bone and lets the collection escape, sometimes leaving a drain in place to allow continued outflow.

This family of procedures is used when infection, blood, or another fluid collection is causing pain, swelling, or systemic illness and needs to be evacuated to relieve pressure and allow antibiotics or the body's own defenses to bring the infection under control.

Anatomy & Axis Detail

Upper Femur, Right

The upper femur, right side, encompasses the femoral head, neck, and greater and lesser trochanters, a region critical to hip biomechanics and vulnerable to fracture in older adults. Drainage here commonly addresses infection following hip fracture fixation or hemiarthroplasty, hematogenous osteomyelitis of the femoral neck, or an abscess tracking along the intertrochanteric region. Because this segment has a precarious blood supply, particularly to the femoral head via the retinacular vessels, infection and its treatment carry a risk of avascular necrosis, making prompt evacuation of purulent material important to limit further vascular compromise. Surgical access typically follows an anterolateral or posterior hip approach, and documentation should note whether hardware was present and whether it was removed or retained.

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.

Coding & Documentation

The documentation should describe fluid or gas being let out of the bone and specify whether a drainage device, such as a catheter or drain, was left behind, since that determines whether a qualifier for drainage device applies. The exact bone and the depth of approach (percutaneous versus open) should be clearly stated to select the right approach value.

A common error is coding Drainage when the procedure actually removed necrotic bone tissue along with the fluid - if dead or infected bone was debrided and taken out, that portion of the case is better captured under Excision, and both root operations may need to be coded if both were performed. Coders should also avoid defaulting to Drainage for procedures where the bone itself was cut without any fluid evacuation.

Commonly Confused With

ExcisionExcision (0QB) is commonly performed alongside Drainage in infected bone, and the two are distinguished by whether tissue was cut out and removed (Excision) versus fluid being let out (Drainage) - both codes may apply to the same operative episode.
DivisionDivision is different because it separates bone tissue without removing any fluid.
ExtirpationExtirpation is sometimes confused with Drainage when a solid matter, like a sequestrum or clot, is taken out rather than a liquid or gas, which would make Extirpation the correct root operation instead.
