What ICD-10 Codes Are Used for Elevated Liver Enzymes?

Navigating the Elevated Liver Enzyme ICD codes is critical for clear diagnostic articulation. Below are some of the primary codes in this category:

R94.5: Abnormal results of liver function studies.
K71.0: Toxic liver disease with cholestasis.
K71.1: Toxic liver disease with hepatic necrosis.
K71.2: Toxic liver disease with acute hepatitis.
K71.3: Toxic liver disease with chronic persistent hepatitis.
K71.4: Toxic liver disease with chronic lobular hepatitis.
K71.50: Toxic liver disease with chronic active hepatitis, not elsewhere classified.
K71.6: Toxic liver disease with hepatitis, not elsewhere classified.
K71.7: Toxic liver disease with fibrosis and cirrhosis of the liver.

Understanding these Elevated Liver Enzyme ICD codes for healthcare professionals ensures accurate documentation and proper billing.

Which Elevated Liver Enzymes ICD Codes Are Billable?

R94.5: Yes, for unspecific liver function anomalies.
K71.0: Yes, when cholestasis is due to toxic substances.
K71.1: Yes, pertaining to hepatic necrosis caused by toxins.
K71.2: Yes, for acute hepatitis from toxic agents.
K71.3: Yes, concerning chronic persistent hepatitis due to toxins.
K71.4: Yes, linked to chronic lobular hepatitis from toxic substances.
K71.50: Yes, addressing non-classified chronic active hepatitis caused by toxins.
K71.6: Yes, for hepatitis cases unclassified but due to toxic agents.
K71.7: Yes, when liver fibrosis and cirrhosis are toxin-induced.

Clinical Information

Elevated liver enzymes signify inflammation or damage to the liver cells. Understanding the nuances is crucial:

Indicators: Elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are primary indicators.
Causes: Medications, hepatitis, fatty liver disease, alcohol consumption, tumors, and other infections.
Diagnosis: Usually via blood tests like ALT, AST, ALP, and bilirubin tests.
Management: Dependent on the cause; may involve lifestyle changes, medications, or interventions for underlying issues.

Synonyms Include:

Liver enzyme elevation
Hepatic enzyme increase
Raised liver function tests (LFTs)
Liver biochemistry anomalies
Hepatic function abnormality

Commonly asked questions

No, not all liver conditions result in elevated enzymes. However, significant liver damage or inflammation often leads to noticeable enzyme increases.

ALT and AST are vital markers in assessing liver health, with ALT being more specific to the liver. Elevated levels usually indicate liver inflammation or damage.

Yes, several medications can cause liver enzyme elevation. Monitoring is essential when on long-term medication to ensure liver health.
