Operation Definition
Taking out or off a device from a body part and putting back an identical or similar device in or on the same body part without cutting or puncturing the skin or a mucous membrane
Procedure Overview
A Change procedure swaps out a urinary drainage device, such as a nephrostomy tube, ureteral stent, or indwelling urinary catheter, for a new one of the same or similar type, using the existing tract rather than creating a new incision or puncture. It is done routinely to prevent tube encrustation, blockage, or infection, since drainage catheters left in place too long degrade and become a source of complications.
These exchanges are typically quick bedside or outpatient procedures rather than surgeries, since the device simply slides out and a replacement slides back in through the same opening. Patients with chronic urinary diversions or long-term nephrostomy drainage may undergo this exchange on a recurring schedule.
Anatomy & Axis Detail
Bladder
The bladder, when equipped with an indwelling drainage device such as a suprapubic catheter, periodically requires that catheter exchanged through its established tract, a routine maintenance step for patients with chronic urinary retention, neurogenic bladder, or outlet obstruction who rely on the tube for ongoing drainage. The old catheter is withdrawn and a replacement of the same or adjusted caliber is passed through the existing suprapubic tract into the bladder lumen, avoiding disruption of the tract itself, which if allowed to close can be difficult to re-establish. Regular exchange reduces the risk of encrustation, balloon rupture, and catheter-associated infection that accompanies long-term indwelling drainage. This differs from a new suprapubic tube placement, which would instead be coded as an insertion through a newly created access.
Approach: External
External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.
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
This root operation applies only when the same external tract is reused without cutting or puncturing skin or mucosa; if imaging guidance or a new percutaneous access is required, the procedure is coded differently, often as Removal followed by Insertion. Documentation should clearly state that an existing device was removed and an identical or similar device placed via the same route. A common assignment mistake is defaulting to Change whenever a catheter is swapped, without confirming that no new access was created, and overlooking cases where a stent exchange also involved cystoscopic manipulation warranting a separate code.
