R5383 - Fatigue or tiredness not caused by a specific known medical condition

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

This code is used when a patient experiences ongoing tiredness, exhaustion, or lack of energy that cannot be explained by a specific medical diagnosis. This type of fatigue goes beyond normal tiredness from lack of sleep or physical activity. It may be related to various factors including stress, lifestyle, medication side effects, or underlying conditions that haven't been identified yet. Your doctor is documenting this symptom to track your condition and may order additional tests to determine if there's an underlying cause.

Additional Information

This is a symptom code rather than a specific diagnosis. The associated lab work (blood counts) suggests your doctor is investigating potential causes of your fatigue, such as anemia or other blood-related conditions. This code helps track your symptoms while further evaluation is conducted.
