Operation Definition

Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part

Procedure Overview

Replacement procedures put in biological or synthetic material that physically takes over for all or part of a urinary structure that has been removed or has failed. The clearest example is placement of an artificial urinary sphincter to manage stress incontinence, or use of a segment of bowel or synthetic material to reconstruct the bladder after part of it has been taken out.

These procedures are chosen when native tissue can no longer perform its job and a substitute - whether a manufactured device or tissue moved from elsewhere in the body - is put in its place. Candidates include patients recovering from bladder cancer surgery, those with severe incontinence unresponsive to other treatments, or people whose urethra has been damaged beyond simple repair.

Because the replaced material functions in place of the original structure going forward, these procedures are usually more involved and longer-lasting in their effect than repair or reposition.

Anatomy & Axis Detail

Ureter, Right

Replacement of the right ureter involves removing a diseased or damaged segment and substituting it with other tissue, most commonly an ileal segment used to bridge a long defect from extensive stricture, malignancy, radiation injury, or failed prior repair. This differs from a direct suture repair in that ureteral continuity is restored using nonureteral tissue rather than the patient's own ureteral wall alone. Because the ureter's small caliber and peristaltic function are difficult to replicate, the replacement segment is fashioned and anastomosed carefully to minimize reflux and maintain adequate drainage from the kidney to the bladder. A stent is typically left across the reconstruction during healing. Documentation should make clear that a segment was excised and substituted with graft tissue, distinguishing this from repair, dilation, or bypass procedures coded elsewhere.

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: Autologous Tissue Substitute

Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of manufactured material.

Coding & Documentation

Documentation must show that material - whether a device, donor tissue, or the patient's own tissue harvested from elsewhere - was put in to functionally substitute for the body part, not just reinforce or patch it. The note should identify the material used and confirm that any diseased or damaged native tissue was removed first, since Replacement often follows a Resection or Excision performed in the same operative session.

A common coding mistake is applying Replacement when the correct root operation is actually Supplement, which reinforces existing tissue without taking over its function entirely. Coders also sometimes overlook that bladder augmentation using a bowel segment qualifies as Replacement because it uses tissue to take over bladder function, and instead code it only as the harvesting procedure.

Commonly Confused With

SupplementReplacement is frequently mixed up with Supplement, where the added material reinforces a body part that still performs its own function, versus Replacement where the material substitutes for the part entirely.
RepairIt is also distinct from Repair, which restores native anatomy without introducing substitute material, and from Insertion, which places a device to assist a still-functioning body part rather than to take its place.
