R319 - Blood in urine of unknown cause

International Classification of Diseases

Last updated: 10/17/2025

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

Hematuria means there is blood present in your urine, which can make it appear pink, red, or brown. 'Unspecified' means your doctor has detected blood in your urine but hasn't yet determined the specific cause. This can happen for many reasons, ranging from minor issues like urinary tract infections or kidney stones to more serious conditions. The blood might be visible to you, or it might only be detected through laboratory testing. Your healthcare provider will likely want to do additional tests to find out why there's blood in your urine and determine the best treatment approach.

Additional Information

This is a symptom that requires investigation to determine the underlying cause. While sometimes due to minor conditions, blood in urine should always be evaluated by a healthcare provider to rule out serious conditions.
