E804 - Gilbert syndrome - a mild, inherited condition affecting liver processing of bilirubin

International Classification of Diseases

Last updated: 3/24/2026

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

Gilbert syndrome is a common, harmless genetic condition where the liver doesn't process bilirubin (a yellow substance from broken-down red blood cells) as efficiently as normal. This can cause mild yellowing of the eyes or skin (jaundice), especially during times of stress, illness, fasting, or dehydration. Most people with Gilbert syndrome have no symptoms and lead completely normal lives. The condition is inherited and affects about 3-12% of the population.

Additional Information

This is a benign condition that does not cause liver damage or require treatment. Patients should be aware that certain medications may need dose adjustments due to reduced liver enzyme activity.
