Official Description

Ureteroplasty, plastic operation on ureter (eg, stricture)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 50700 refers to ureteroplasty, which is a surgical intervention aimed at repairing the ureter, the tube that carries urine from the kidney to the bladder. This operation is typically indicated when there is a stricture, or narrowing, of the ureter due to injury, disease, or congenital abnormalities. During ureteroplasty, the surgeon exposes the ureter and isolates the affected segment that is narrowed or damaged. The specific technique used for the plastic repair of the ureter can vary based on the nature of the abnormality present. One common method employed is Z-plasty, which involves making horizontal and oblique incisions around the narrowed area. These incisions create flaps of tissue that can be rotated and reattached, effectively widening the lumen of the ureter at the site of the stricture. This surgical approach not only alleviates the obstruction but also aims to restore normal urinary flow, thereby improving the patient's overall renal function and health.

1. Indications

The procedure of ureteroplasty (CPT® Code 50700) is indicated for specific conditions affecting the ureter. These include:

  • Ureteral Stricture - A condition where the ureter is narrowed, leading to obstruction of urine flow.
  • Ureteral Injury - Damage to the ureter that may occur due to trauma, surgical complications, or other medical conditions.
  • Congenital Abnormalities - Structural defects present at birth that affect the ureter's normal function.

2. Procedure

The ureteroplasty procedure involves several critical steps to ensure effective repair of the ureter. These steps include:

  • Step 1: Exposure of the Ureter - The surgeon begins by making an incision in the abdominal wall or flank to access the ureter. Once the incision is made, the surrounding tissues are carefully dissected to expose the ureter fully.
  • Step 2: Isolation of the Affected Segment - After the ureter is exposed, the narrowed or damaged portion is identified and isolated. This step is crucial as it allows the surgeon to focus on the specific area that requires repair.
  • Step 3: Incision and Flap Creation - Horizontal and oblique incisions are made over the narrowed segment of the ureter. These incisions create flaps of tissue that can be manipulated during the repair process.
  • Step 4: Flap Rotation and Re-anastomosis - The created flaps are then rotated and reattached to each other, a technique known as Z-plasty. This maneuver increases the diameter of the ureter at the site of the stricture, facilitating improved urine flow.
  • Step 5: Closure - Once the repair is complete, the surgeon carefully closes the incision in the abdominal wall or flank, ensuring that all layers of tissue are properly aligned and sutured.

3. Post-Procedure

After the ureteroplasty procedure, patients typically require monitoring for any complications, such as infection or urinary leakage. Post-operative care may include pain management, hydration, and possibly the placement of a stent to ensure proper urine flow while the ureter heals. Patients are usually advised to follow up with their healthcare provider to assess the success of the repair and to monitor kidney function. Recovery time can vary based on the individual and the extent of the surgery, but most patients can expect to resume normal activities within a few weeks, depending on their overall health and the specifics of their surgical procedure.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).

X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
