Summary & Overview
CPT 50949: Laparoscopic Ureteral Procedure, Unlisted
CPT code 50949 designates unlisted laparoscopic procedures of the ureter and is used when no specific CPT code applies. This category-level code matters nationally because it supports billing for atypical or novel laparoscopic ureteral interventions that fall outside standard code sets, ensuring providers can report services while payers evaluate medical necessity and reimbursement. The analysis covers major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical scope and billing context for 50949, including where these services are typically performed (hospital outpatient departments and ambulatory surgical centers), and how payers commonly approach unlisted laparoscopic ureter procedures. The publication outlines typical documentation requirements and the role of unlisted codes in coding workflows, plus benchmarks and policy considerations relevant to national payer adjudication. Data not available in the input is noted where applicable. The piece is intended to equip coding managers, surgical billing staff, and revenue integrity teams with a concise reference on when and why 50949 is used and what to expect in payer interactions.
Billing Code Overview
CPT code 50949 is used to report laparoscopic procedures of the ureter that do not have a specific code. The descriptor indicates this is an unlisted laparoscopic ureteral surgery code intended for procedures that fall outside existing, more specific CPT listings.
Service Type: Laparoscopic ureteral surgery (unlisted procedure)
Typical Site of Service: Hospital outpatient department or ambulatory surgical center

Clinical & Coding Specifications
Clinical Context
A 47-year-old female presents with intermittent right flank pain and recurrent urinary tract infections. Imaging (CT urogram) demonstrates a mid-ureteral stricture with proximal hydroureteronephrosis and suspected ureteral endometriosis. After urology evaluation, the patient is scheduled for a diagnostic and therapeutic laparoscopic ureteral procedure under general anesthesia. In the operating room, the surgeon performs laparoscopic exploration of the ureter, mobilization of the affected segment, excision of fibrotic tissue, and primary ureteral repair with ureteroneocystostomy planned if required. Intraoperative decision-making may include stent placement, limited ureterotomy, or conversion to an open approach if exposure is inadequate. Typical perioperative workflow includes preoperative antibiotics, cystoscopy for retrograde evaluation as indicated, laparoscopic ureteral dissection, intraoperative ureteral stent placement if repair performed, postoperative imaging to confirm patency, and short inpatient observation or same-day discharge depending on complexity and comorbidities.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or complexity is substantially greater than typical for the procedure (document justification). |
51 | Multiple procedures | Use when additional unrelated surgical procedures are performed at the same operative session. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned. |
53 | Discontinued procedure | Use when procedure is started but terminated due to extenuating circumstances. |
59 | Distinct procedural service | Use to indicate a separate, distinct procedure not normally billed together. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team | Use when multiple specialists participate as part of a documented surgical team. |
73 | Discontinued outpatient hospital/ambulatory surgery before anesthesia | Use when outpatient procedure cancelled after patient taken to OR but before anesthesia. |
78 | Unplanned return to OR | Use when patient returns to operating room for related procedure during postoperative global period. |
AS | Ambulatory surgical center facility fee | Use to denote services provided in an ambulatory surgical center when reporting facility component. |
LT | Left side | Use to indicate procedure performed on the left-side ureter. |
RT | Right side | Use to indicate procedure performed on the right-side ureter. |
59 | Distinct procedural service | Use when separate procedures during same session are unrelated; document distinct anatomic site or session. |
| Taxonomy Code | Specialty | Notes |

| 208U00000X | Urology | Primary specialty performing ureteral laparoscopic procedures. |
| 207L00000X | General Surgery | General surgeons with endourology or minimally invasive training may perform ureteral surgery. |
| 363A00000X | Obstetrics & Gynecology | Gynecologic surgeons may perform ureterolysis or ureteral interventions when related to endometriosis or pelvic pathology. |
| 282N00000X | Pediatric Urology | Urologists specializing in children perform laparoscopic ureteral procedures in pediatric populations. |

Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
N13.5 | Unspecified hydronephrosis | Represents ureteral obstruction leading to dilatation; commonly addressed with ureteral surgery. |
N13.2 | Hydronephrosis with ureteral stricture | Directly indicates a ureteral stricture requiring surgical correction. |
N20.1 | Calculus of ureter | Ureteral stones causing obstruction may require laparoscopic ureteral procedures when endoscopic removal is not possible. |
N28.1 | Renal insufficiency, not elsewhere classified | Chronic obstruction from ureteral pathology can lead to impaired renal function influencing surgical planning. |
N83.3 | Ureteral endometriosis (use with N80.*) | Endometriosis involving the ureter can necessitate laparoscopic ureterolysis or resection. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |

50590 | Ureterolithotomy, with or without pyelolithotomy, laparoscopic | Performed when ureteral obstruction is due to impacted stone; may be an alternative or concurrent laparoscopic ureteral procedure. |
50730 | Ureteral reimplantation, ureteroneocystostomy, open; without antireflux procedure | May be performed if laparoscopic reconstruction is not feasible or conversion to open repair is required for definitive reimplantation. |
52332 | Cystoureteroscopy, with ureteroscopy and/or pyeloscopy; with removal of stone(s) | Diagnostic/therapeutic endoscopic procedure often performed preoperatively or intraoperatively for evaluation or stone management and may accompany laparoscopic ureteral procedures. |
