Summary & Overview

CPT 50600: Ureteral Incision and External Drainage

CPT code 50600 defines a urologic surgical procedure to incise the ureter for inspection or to place an external drainage catheter from the ureter to the skin. This code captures interventions used to evaluate ureteral integrity, relieve obstruction, or provide external urinary drainage when internal stenting is not suitable. Nationally, accurate coding for procedures like 50600 matters for procedure reporting, hospital case mix, surgical quality measurement, and appropriate payment for complex urologic care.

Key payers commonly relevant to billing and reimbursement for this procedure include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and service setting for the code, typical claims and billing considerations tied to urologic surgical services, and an outline of what documentation elements support billing. The publication also summarizes benchmarks and policy context where available and highlights areas where data was not provided.

This summary serves clinicians, coding professionals, and policy analysts seeking a national-level briefing on CPT code 50600, its clinical purpose, and the payer landscape that typically covers such urologic surgical services.

Billing Code Overview

CPT code 50600 describes a surgical procedure in which the provider makes an incision in the ureter to inspect it or establishes external drainage by placing a catheter from the ureter to the patient’s skin. This procedure is a ureteral incision and/or external drainage placement.

Service type: Surgical urologic procedure involving ureteral exploration and drainage.
Typical site of service: Hospital operating room or ambulatory surgical center where urologic procedures requiring incision and catheter placement are performed.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting with flank pain, hydronephrosis, recurrent urinary tract infections, or suspected ureteral obstruction due to stone, stricture, extrinsic compression, or tumor. Imaging (CT urogram, IVP, renal ultrasound) demonstrates proximal or distal ureteral dilation or an obstructing lesion. The urologist schedules an open or limited incision of the ureter for direct inspection (50600) or placement of a percutaneous or cutaneous ureteral drainage catheter (ureterostomy or externalized nephroureteral drain) when endoscopic retrograde stenting is not feasible or has failed.

Preoperative workflow includes history and physical, consent for possible ureteral exploration and drainage, review of imaging, and perioperative antibiotics. Intraoperative steps include identification of the ureter via open or limited incision, inspection and possible biopsy of suspicious lesions, and placement of an external drainage catheter between the ureter and the skin with securement. Postoperative management includes dressing and drain care, monitoring urine output from the catheter, imaging to confirm position and drainage, outpatient or inpatient education for catheter maintenance, and scheduled follow-up for definitive repair or stent exchange.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`N13.2`	Hydronephrosis with renal and ureteral calculous obstruction	Common indication when ureteral obstruction from stone causes hydronephrosis requiring drainage.
`N13.4`	Hydronephrosis due to other obstructive uropathy	General code for obstructive processes causing dilation necessitating inspection or drainage.
`N13.6`	Pyonephrosis	Infected collecting system with obstruction often requires drainage of the ureter or renal collecting system.
`N28.1`	Other disorders of kidney and ureter in neoplastic disease	Ureteral obstruction from tumor may require incision for inspection and drainage or biopsy.
`N20.0`	Calculus of kidney	Renal stones causing ureteral obstruction can lead to this procedure when endoscopic removal fails.
`N20.1`	Calculus of ureter	Direct ureteral stones are a frequent indication for ureteral incision or external drainage when retrograde access fails.
`N32.89`	Other specified disorders of bladder	Relevant when bladder pathology prevents retrograde stenting and external ureteral drainage is necessary.
`R33.9`	Retention of urine, unspecified	Acute urinary retention with associated upper tract dilation may prompt surgical drainage measures including ureteral catheterization/drainage.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`52000`	Cystourethroscopy, with or without collection of specimen(s) by brushing or washing	Performed pre- or intraoperatively to evaluate ureteral orifices and attempt retrograde stent placement prior to open ureter incision or external drainage.
`52005`	Cystourethroscopy with ureteral catheterization, with or without irrigation and/or contrast instillation	Used to attempt retrograde ureteral catheterization and contrast study before selecting open ureteral incision or external drain placement.
`50240`	Nephrostomy, percutaneous, with catheter placement, including imaging guidance when performed	Alternative or adjunct when antegrade renal drainage is required instead of cutaneous ureteral drainage.
`50590`	Insertion of indwelling ureteral stent (e.g., double-J), with or without cystoscopy	If internal stenting is successful, this may obviate the need for an external ureteral drainage catheter or follow as a definitive management.
`52370`	Cystoureteroscopy, with ureteroscopy and removal of stone(s) by ureteroscopic approach	Performed when ureteral stones are the cause; may be attempted before incision/drainage.
`54125`	Biopsy of ureteral lesion (open)	If inspection reveals a suspicious ureteral lesion, open biopsy codes or pathology-related procedures may be performed during the same operative session.
