Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision in the urinary system involves cutting out a piece of an organ, such as a wedge of kidney tissue for biopsy, a section of bladder wall containing a suspicious lesion, or part of a ureter, while leaving the rest of the structure intact. It is performed to diagnose disease by examining tissue under a microscope, or to remove a localized abnormal area without sacrificing the whole organ.
Anatomy & Axis Detail
Kidney Pelvis, Left
In the left renal pelvis, excision similarly targets a localized abnormality, such as a urothelial tumor or a polyp identified on prior imaging or ureteroscopic biopsy, removed endoscopically or through an open approach without taking the entire kidney or collecting system. This nephron-sparing strategy is weighed against the risk of tumor recurrence within the upper tract, and pathology confirmation of margins is a standard part of the workup. Coders should distinguish this excision from a more extensive nephroureterectomy performed for higher-grade disease, and confirm from documentation that the resected tissue originated specifically from the pelvis rather than an adjacent calyx or the proximal ureter.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
Coding & Documentation
Assignment depends on identifying the exact body part biopsied or partially removed and the surgical approach (open, percutaneous, or via endoscope). Operative and pathology notes together confirm that only a portion of the structure was taken, since removal of an entire organ is coded as Resection instead. A frequent mistake is defaulting to Excision for any biopsy language without checking whether the documentation actually describes complete organ removal, or failing to code a closed (percutaneous needle) biopsy separately from an open surgical biopsy performed during the same encounter.
