Urology and Urological Radiology Procedures (October 2005)
October 2005 pages 18-22 Coding Commentary:Urology and Urological Radiology Procedures The cliche "small but mighty" can be applicable to both the heart and kidneys because these organs are each normally about the size of a fist. Although small, the interdependent functions of these organs is "mighty" important to our physiologic well being. Together with the skin and the respiratory system, the kidneys are the body's primary excretory organs. Urine formation and excretion (about 1 to 1.5 L per day) is a life-sustaining function representing the end product of metabolism. Normally, urine flows from the kidneys down through the...

Article Overview
This CPT® Assistant article explains coding topics related to urology and urological radiology procedures in the context of renal, ureteral, and nephrostomy-related services. It is aimed at coders, billers, and clinicians who document or report these services and need to understand how the article organizes procedure categories, imaging components, and example scenarios. The piece also touches on anatomy and physiology background to frame the procedural discussion and emphasizes the importance of documentation for reporting related services.
Why This Topic Matters
Urology and interventional radiology services often involve multiple related components, imaging support, and complex documentation. This article helps readers identify the scope of the discussed procedures and the broader coding areas addressed in the guidance.
Article Sections
-
Coding Commentary: Urology and Urological Radiology Procedures
Introduces the article’s overall focus and the clinical context for the coding discussion. It provides background on urinary tract anatomy and related procedural themes.
-
Commonly Asked Questions About Codes 50390-50395
Presents coding questions and general guidance related to selected urologic and radiologic services. The section centers on documentation, imaging support, and how the procedures are organized within the article.
-
Codes 50390 and 74425
Addresses a question set involving a renal-pelvis procedure and its associated radiology supervision and interpretation. The discussion focuses on documentation and the relationship between the procedure and imaging component.
-
Codes 50392, 50393, 74475, 74480
Covers a separate question set involving nephrostomy and ureteral catheter or stent services with associated imaging support. The section compares related services and discusses reporting considerations in general terms.
-
Codes 50395 and 74485
Reviews guidance for a tract-creation and dilation-related procedure category and its imaging component. The section explains the broader circumstances in which these services are discussed in the article.
-
Clinical Example 1
Provides a narrative procedure example involving ureteral intervention and nephrostomy exchange. The example is used to illustrate how the article’s coding concepts apply to a complex clinical scenario.
-
Clinical Example 2
Provides a second procedure example involving bilateral nephrostomy tube placement. It shows how the article uses a detailed case to illustrate documentation and reporting considerations.
-
Simple Anatomy and Physiology Review
Summarizes basic kidney and urinary system anatomy and function. This section serves as background for understanding the procedures discussed earlier in the article.
-
Introduction of Catheter Into Renal Pelvis
Introduces a glossary-style reference segment for anatomical and physiological terms relevant to the article. It supports reader understanding of the urologic terminology used throughout the piece.
-
Glossary
Defines selected kidney and urinary system terms referenced in the article. The glossary is included as supporting background rather than coding guidance.
