Official Description

Introduction of guide into renal pelvis and/or ureter with dilation to establish nephrostomy tract, percutaneous

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 50395 involves the introduction of a guide into the renal pelvis and/or ureter, accompanied by dilation to create a nephrostomy tract through a percutaneous approach. This procedure is typically performed in the flank region, where the skin over the kidney is first cleansed to minimize the risk of infection. A local anesthetic is then administered to ensure patient comfort during the procedure. Following this, a needle is carefully inserted, allowing for the advancement of a guidewire through the skin and into the renal pelvis or ureter. This step is crucial as it provides a pathway for subsequent instruments. The procedure is conducted under radiologic supervision, which is separately reportable, ensuring that the placement of the guidewire is accurately monitored. Once the guidewire is in place, a series of dilators are advanced over it to gradually enlarge the tract, facilitating the establishment of a nephrostomy. The dilation process is essential for creating an adequately sized tract, and once the desired diameter is achieved, the dilator is removed, leaving the nephrostomy tract ready for further intervention or drainage as needed.
