Code	Description	When to Use	Key Documentation
K70.10	Alcoholic hepatitis without ascites	Use when alcoholic hepatitis is confirmed with elevated GGT and alcohol use.	GGT >100 U/L AST:ALT ratio ≥2:1 Documented alcohol intake
R94.5	Abnormal results of liver function studies	Use when liver function tests are abnormal but no specific diagnosis is made.	GGT > ULN but <100 U/L Normal bilirubin/albumin

Documentation & Coding Risks

Avoid these common issues when documenting Gamma-Glutamyl Transferase.

Failing to document alcohol use

Impact

Clinical: Misdiagnosis of liver condition, Regulatory: Non-compliance with coding standards, Financial: Denial of claims

Mitigation

Always ask about alcohol use in liver disease cases, Document findings clearly

Using unspecified liver disease codes

Impact

Reimbursement: Higher denial rates for unspecified codes, Compliance: Increased audit risk, Data Quality: Poor data quality and clinical accuracy

Mitigation

Use specific codes like K70.10 when criteria are met.

Unspecified liver disease codes

Impact

High audit risk when using unspecified codes without supporting documentation.

Mitigation

Use specific codes and ensure documentation supports the diagnosis.
