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

Ureter, Left

The left ureter carries urine from the left renal pelvis to the bladder along a retroperitoneal course that crosses the iliac vessels and runs medial to the gonadal vessels. Excision here removes a portion of this muscular tube, typically for a segment involved by a stricture-associated tumor, a fibrotic or ischemic segment, or a localized malignancy such as urothelial carcinoma confined to one length of duct. Because the ureter is a conduit rather than a reservoir, removing a segment usually requires reconstruction, such as ureteroureterostomy or reimplantation, performed as a separate procedure from the excision itself. Coders should confirm from the operative note whether the resected tissue represents a discrete segment (Excision) versus the entire ureter (Resection), and note laterality explicitly since right and left ureters are captured under separate values.

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.

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.

Commonly Confused With

ResectionExcision is most often confused with Resection - the dividing line is whether any of the organ remains after the procedure.
ExtirpationIt also differs from Extirpation, which removes abnormal solid matter like a stone or necrotic debris rather than a piece of the organ itself, and from Destruction, which eliminates tissue in place without removing a specimen.
