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
Metatarsal-Phalangeal Joint, Right
The right metatarsal-phalangeal joints, most notably the first MTP joint at the base of the great toe, bear significant load during the terminal push-off phase of gait and are commonly affected by hallux valgus, hallux rigidus, or traumatic injury. Removal in this location typically involves taking out Kirschner wires, screws, or a joint spacer placed during bunion correction, fusion, or implant arthroplasty. Because the first MTP joint is superficial and subject to repeated mechanical stress with each step, retained hardware often becomes symptomatic, prominent, or loosened, prompting a later procedure to extract it. Coders should note which specific metatarsal-phalangeal joint is involved, since the great toe joint is addressed far more often than the lesser toe joints and carries distinct clinical significance for gait mechanics.
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.
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.
