What is the ICD-10 code for elevated liver enzymes?

The ICD-10 code for elevated liver enzymes without a known cause is R74.01. If a cause is identified, such as NAFLD, use the appropriate code like K76.0.

When should R74.01 be used?

Use R74.01 when ALT/AST levels are elevated without a known underlying cause. If a cause is identified, code the cause first.

Documentation & Coding Risks

Avoid these common issues when documenting Elevated Liver Enzymes.

Vague documentation of liver enzyme elevation

Impact

Clinical: Inaccurate diagnosis and treatment plans., Regulatory: Potential audit failures., Financial: Incorrect billing and reimbursement.

Mitigation

Require specific enzyme levels in documentation.

Using R74.01 when an underlying cause is known

Impact

Reimbursement: May lead to incorrect DRG assignment., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Identify and code the underlying cause first, such as K76.0 for NAFLD.

Incorrect sequencing of codes

Impact

Failure to code the primary cause first.

Mitigation

Regular training on ICD-10 sequencing rules.
