A419 - Sepsis (severe blood infection) where the specific bacteria or organism causing the infection has not been identified

International Classification of Diseases

Last updated: 10/3/2025

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

Sepsis is a serious medical condition that occurs when your body has an overwhelming response to an infection. This code indicates that you have sepsis, but doctors haven't yet identified the specific bacteria, virus, or other organism causing the infection. Sepsis can develop from infections anywhere in your body - such as pneumonia, urinary tract infections, or skin infections - and can quickly become life-threatening if not treated promptly. The 'unspecified organism' means that while sepsis has been diagnosed based on your symptoms and test results, additional testing may be needed to identify exactly what is causing the infection so that the most targeted treatment can be provided.

Additional Information

Sepsis is a medical emergency requiring immediate treatment. Early recognition and treatment significantly improve outcomes. This code may be updated once the specific organism is identified through culture results.
