CPT 51045 Ureteral Stent Placement Reimbursement

CPT code 51045 denotes a cystotomy approach to place a ureteral stent or catheter to relieve a ureteral stricture or blockage. This code captures a targeted urologic surgical intervention used to restore urinary drainage and prevent complications from obstructive uropathy. Nationally, accurate coding for this procedure matters for clinical documentation, quality measurement, and appropriate facility and professional billing.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, as well as what to expect in payer coverage considerations and common billing practices. The publication summarizes relevant benchmarks, coding nuances, and recent policy developments that affect authorization, site-of-service designation, and bundling or global period implications. Clinical implications such as indications (ureteral stricture or obstruction), expected perioperative setting (hospital operating room, ambulatory surgery center), and the primary goals of the procedure (restoring ureteral patency, relieving obstruction) are covered to support coding accuracy and administrative review.

Data not available in the input is noted where applicable, and readers will be directed to payer-specific policies and clinical guidelines for authorization criteria and documentation requirements.

Billing Code Overview

CPT code 51045 describes a surgical procedure in which the provider makes an incision into the urinary bladder (cystotomy) to insert a stent or catheter into the ureter. The procedure is performed to treat a ureteral stricture or obstruction by establishing or restoring patency of the ureteral lumen.

Service type: Surgical, urologic endourologic intervention
Typical site of service: Operating room or procedure suite in an inpatient or outpatient hospital setting; may also be performed in ambulatory surgical centers depending on clinical circumstances

Clinical Context

A 58-year-old male presents with progressive right flank pain, hydronephrosis on renal ultrasound, and rising serum creatinine. Imaging via non-contrast CT identifies a ureteral obstruction near the distal ureter consistent with a ureteral stricture. The urology team schedules a transvesical ureteral catheter/stent placement via cystotomy to relieve obstruction. Under general anesthesia in an operating room, the surgeon makes a small suprapubic incision into the bladder, identifies the affected ureteral orifice, and inserts a ureteral stent or catheter through the cystotomy into the ureter under fluoroscopic guidance. The procedure may follow diagnostic cystoscopy and retrograde pyelography to localize the obstruction. Postoperatively the patient is observed in a recovery area and plans are made for outpatient follow-up for stent removal or exchange.

`26`	Professional component	Use when billing only the physician professional component separate from technical facility charges.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned.

Taxonomy Code	Specialty	Notes
208U00000X	Urology	Primary specialty performing ureteral stent or catheter placement via cystotomy.
2082P0800X	General Surgery	May perform in settings where urologist not available, particularly trauma or complex abdominal cases.
207Q00000X	Family Medicine	Rarely performs in procedural clinics; typically refers to specialists.
208800000X	Pediatric Urology	Performs pediatric variants of the procedure for congenital ureteral obstruction.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`N13.2`	Hydronephrosis with ureteral stricture	Common indication when a ureteral stricture causes upstream dilation and requires stent placement.
`N13.0`	Hydronephrosis due to ureteral stricture	Indicates obstruction of urine flow prompting decompression via ureteral stent or catheter.
`N13.8`	Other obstructive and reflux uropathy	Captures varied obstructive etiologies that may necessitate cystotomy and stent placement.
`N20.1`	Calculus of ureter	Ureteral stones causing obstruction may lead to stent placement via bladder incision if endoscopic removal is not feasible.
`N99.0`	Postprocedural urinary system disorder	Used when complications after prior urinary procedures result in need for catheter or stent placement.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`52000`	Cystourethroscopy, with or without irrigation, instillation, or ureteral catheterization, exclusive of radiologic service	Often performed before `51045` for diagnostic cystoscopy and attempt at retrograde stent placement; may precede open cystotomy if endoscopic approach fails.
`52005`	Cystourethroscopy with ureteral catheterization, with manipulation (separate procedure)	May be used when additional manipulation or catheter placement is performed endoscopically in the same session.
`51047`	Incision of bladder to insert ureteral catheter or stent, with irrigation and/or removal of stones (if listed separately)	Related open bladder incision procedures; codes may be considered when concomitant stone removal or additional bladder work is performed.
`50710`	Exploration of ureter, with repair or reimplantation	Performed when definitive ureteral reconstruction is required beyond stenting for stricture or injury.
`52010`	Cystourethroscopy with ureteral therapy (e.g., dilation)	May be performed in conjunction when ureteral dilation is attempted via cystoscopic approach rather than open cystotomy.
