Operation Definition
Taking out or off a device from a body part
Procedure Overview
Removal procedures take out a device that was previously placed in a lower joint, such as internal fixation hardware, a spacer, drainage tubing, or an external fixator frame. These procedures are performed once the device has served its purpose - for example, after a fracture has healed and screws are no longer needed - or when a device is causing pain, infection, or mechanical irritation and needs to come out. Removal can be a planned, staged part of treatment or an unplanned procedure prompted by a complication.
Because the device itself, not the joint tissue, is the focus, these procedures are typically less extensive than the original surgery that placed the device, though scar tissue and bony ingrowth around older hardware can make removal technically demanding.
Anatomy & Axis Detail
Ankle Joint, Left
The left ankle joint is the corresponding tibiotalar mortise on the opposite side, formed by the same tight articulation of tibia, fibula, and talus that makes it both highly load-bearing and mechanically unforgiving of retained foreign material. Removal here targets hardware fragments, cement, or debris left in the joint following a prior left ankle fracture fixation or fusion procedure, distinct from any material addressed on the right side. The joint's narrow congruent shape and thin surrounding soft tissue envelope mean that even small retained fragments can cause mechanical symptoms or impingement, often prompting imaging-guided retrieval. As with the right ankle, careful laterality documentation matters given how often ankle fixation procedures are staged or performed bilaterally over a patient's history.
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: Infusion Device
Infusion Device denotes a device left in place to deliver medication, fluids, or other substances into a body part over time, such as an intrathecal or epidural pump. It is distinct from devices that merely monitor or mechanically support tissue, since its function is ongoing pharmacologic or fluid delivery rather than structural replacement. Common placements include the spinal canal, peritoneal cavity, and vascular access sites.
Coding & Documentation
The operative note must identify the specific device being taken out and confirm nothing is being put in its place; if a new device replaces the old one, the more specific combination root operation (such as Revision) may apply instead of a plain Removal. The body part coded is the joint from which the device is taken, using the device's original insertion site. A recurring error is coding Removal when hardware is being exchanged for a different device during the same procedure, which should instead be captured as Revision, or when the device is being taken out specifically because it failed, which some coders mistakenly still classify simply as Removal without checking whether Revision criteria are met.
