R945 - Blood test results showing your liver isn't working normally

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 means that blood tests checking how well your liver is working came back with abnormal results. Your liver performs many important jobs like filtering toxins from your blood, making proteins, and helping with digestion. When liver function tests are abnormal, it could indicate various conditions ranging from minor issues like medication effects or temporary inflammation to more serious liver problems. The abnormal results don't tell us exactly what's wrong - they're like a warning light that tells your doctor your liver needs more investigation. Your healthcare provider will likely want to do additional tests, review your medications, and possibly repeat the tests to determine what's causing the abnormal results and whether treatment is needed.

Additional Information

This is a diagnostic code indicating test results, not a specific disease. The underlying cause needs to be determined through further evaluation. Many factors can cause abnormal liver tests including medications, alcohol use, infections, or liver diseases.
