The International Classification of Diseases, 10th Revision (ICD-10), provides a comprehensive system for coding various health conditions, including those related to liver function tests (LFTs). LFTs are a group of tests used to assess liver function and diagnose liver diseases. Here are 5 ICD-10 codes related to LFTs, along with a brief description of each:
ICD-10 Codes for Liver Function Tests

Understanding the ICD-10 codes for LFTs is essential for accurate diagnosis, treatment, and billing purposes. The following codes are used to report abnormal liver function test results:
R94.5 - Abnormal liver function test
This code is used to report abnormal liver function test results, including elevated liver enzymes, bilirubin, or other liver function parameters. It is a non-specific code that can be used when the specific abnormality is not specified.
K76.0 - Fatty liver
This code is used to report fatty liver disease, also known as hepatic steatosis. Fatty liver is a condition characterized by the accumulation of excess fat in the liver cells, which can lead to liver damage and dysfunction.
K76.1 - Chronic passive congestion of liver
This code is used to report chronic passive congestion of the liver, which occurs when there is a backup of blood in the liver due to right-sided heart failure or other conditions. This can lead to liver damage and dysfunction.
K77.0 - Liver disorders in diseases classified elsewhere
This code is used to report liver disorders that occur in diseases classified elsewhere, such as liver involvement in infectious diseases, autoimmune disorders, or other conditions.
R94.6 - Unsatisfactory liver function test
This code is used to report unsatisfactory liver function test results, which may indicate liver disease or dysfunction. It is often used when the test results are unclear or inconclusive.
ICD-10 Code | Description |
---|---|
R94.5 | Abnormal liver function test |
K76.0 | Fatty liver |
K76.1 | Chronic passive congestion of liver |
K77.0 | Liver disorders in diseases classified elsewhere |
R94.6 | Unsatisfactory liver function test |

Key Points
- ICD-10 codes are used to report various health conditions, including liver function tests.
- R94.5 is used to report abnormal liver function test results.
- K76.0 is used to report fatty liver disease.
- K76.1 is used to report chronic passive congestion of the liver.
- K77.0 is used to report liver disorders in diseases classified elsewhere.
What is the purpose of ICD-10 codes for liver function tests?
+The purpose of ICD-10 codes for liver function tests is to provide a standardized system for reporting and coding liver function test results, which can help with diagnosis, treatment, and billing purposes.
How are ICD-10 codes used in clinical practice?
+ICD-10 codes are used in clinical practice to document patient diagnoses, report test results, and facilitate communication between healthcare providers. They are also used for billing and insurance purposes.
What is the difference between R94.5 and R94.6?
+R94.5 is used to report abnormal liver function test results, while R94.6 is used to report unsatisfactory liver function test results. Unsatisfactory results may indicate liver disease or dysfunction, but may also be due to other factors such as laboratory error or incomplete testing.
