N138 - Other obstructive and reflux uropathy - blockage or backup of urine in the urinary system

International Classification of Diseases

Last updated: 3/13/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code represents a condition where there is obstruction (blockage) or reflux (backward flow) of urine somewhere in the urinary system that doesn't fit into other specific categories. This can affect the kidneys, ureters (tubes that carry urine from kidneys to bladder), or other parts of the urinary tract. The obstruction or reflux can prevent normal urine flow, potentially leading to kidney problems if not treated. This is a 'catch-all' code used when the specific type of urinary obstruction or reflux doesn't match other more specific diagnostic codes.

Additional Information

This is a non-specific code that covers various types of urinary obstructions and reflux conditions. The actual treatment and prognosis depend on the specific underlying cause and location of the obstruction or reflux.
