Decision Criteria
clinical Criteria
- Biopsy confirms hepatocellular carcinoma
coding Criteria
- Use C22.0 for primary liver cancer only
Applicable To
- Primary liver cancer
Excludes
- Secondary liver cancer (C78.7)
Clinical Validation Requirements

Coding Notes
- Ensure documentation specifies primary liver cancer to avoid confusion with metastatic disease.
C78.7 - Secondary malignant neoplasm of liver
Use when liver cancer is secondary to another primary cancer.
Applicable To
- Metastatic liver cancer
Excludes
- Primary liver cancer (C22.0)
Clinical Validation Requirements
- Pathology report indicating metastasis from another primary site
Coding Notes
Always sequence the primary cancer code before C78.7.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Malignant Neoplasm of Liver to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C22.0.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Always specify the origin of the cancer., Use clear terminology in documentation.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate cancer registry data.
Mitigation Strategy
Use C78.7 for secondary liver cancer and code the primary site first.
Impact
Incorrectly coding metastatic liver cancer as primary.
Mitigation Strategy
Implement training on proper sequencing and documentation.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
