| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C22.1 | Intrahepatic cholangiocarcinoma | Use when the primary site of cholangiocarcinoma is confirmed as intrahepatic. |
|
| C78.7 | Secondary malignant neoplasm of liver | Use when documenting liver metastasis from a primary cholangiocarcinoma. |

Decision Criteria
clinical Criteria
- Confirmed intrahepatic origin via imaging and biopsy.
Applicable To
- Intrahepatic bile duct carcinoma
Excludes
- Extrahepatic bile duct carcinoma (C24.0)
Clinical Validation Requirements

- Imaging showing intrahepatic mass
Code-Specific Risks
- Misclassification with extrahepatic cholangiocarcinoma
Coding Notes
- Ensure anatomical specificity in documentation to avoid misclassification.
C78.7 - Secondary malignant neoplasm of liver
Use when documenting liver metastasis from a primary cholangiocarcinoma.
Applicable To
- Liver metastasis
Excludes
- Primary liver cancer (C22.0)
Clinical Validation Requirements
- Imaging showing liver lesions
- Biopsy confirming metastatic origin
Coding Notes
Sequence as primary when the focus of treatment is on the metastasis.
Ancillary Codes

C24.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Metastatic Cholangiocarcinoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C22.1.
Impact
Clinical: Incomplete clinical picture., Regulatory: Non-compliance with coding standards., Financial: Potential loss in reimbursement.
Mitigation Strategy
Cross-check documentation for all metastatic sites., Use coding software alerts.
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting treatment decisions.
Mitigation Strategy
Use C24.0 for perihilar cholangiocarcinoma.
Impact
Failure to document all metastatic sites can lead to audit flags.
Mitigation Strategy
Implement thorough documentation protocols and regular audits.
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.
