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 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.

Qualifier: Diagnostic

Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.

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.
