Use for congenital intrahepatic ductal dilation.
Applicable To
- Caroli disease
- Cystic dilation of intrahepatic ducts
Clinical Validation Requirements
- Imaging showing dendritic ductal pattern
- Absence of acquired causes
Coding Notes
Document congenital nature and specific imaging findings.
C22.1 - Intrahepatic bile duct carcinoma
Use when malignancy is confirmed in intrahepatic ducts.
Applicable To
- Mass lesion with ductal dilation
Clinical Validation Requirements
- Biopsy-proven adenocarcinoma
- Mass lesion correlating with dilated ducts
Coding Notes
Ensure biopsy confirmation of malignancy.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Intrahepatic Biliary Ductal Dilation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K83.8.
Impact
Clinical: May lead to incorrect diagnosis and treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Use specific terminology, Provide imaging details
Impact
Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and statistics.
Mitigation Strategy
Ensure documentation specifies 'intrahepatic' and provides imaging evidence.
Impact
Failure to specify intrahepatic location can lead to audit issues.
Mitigation Strategy
Ensure detailed documentation and correct code selection.
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.
