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, Right
Excision within the right renal pelvis involves removing a discrete lesion, most often a urothelial tumor arising from the lining of this collecting structure, while leaving the surrounding kidney tissue in place. Because upper tract urothelial carcinoma can be multifocal and behaves differently from bladder cancer, localized excision is sometimes chosen for select low-grade lesions, particularly when preserving renal function is a priority, though many cases still proceed to more extensive resection. The operative note should specify that the procedure was confined to pelvis tissue rather than the ureter or renal parenchyma broadly, since accurate body part selection depends on the lesion's precise anatomic origin.
Approach: Via Natural or Artificial Opening
Via Natural or Artificial Opening means the instrument reaches the target site by passing through an existing body orifice, such as the mouth or urethra, or a surgically created opening like a stoma, without additional incision or scope guidance. It is distinguished from the Endoscopic variant by the absence of a visualizing scope, and from External by actually traversing into the body through that opening.
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.
