| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K80.50 | Calculus of bile duct without cholangitis or cholecystitis, without obstruction | Use when a CBD stone is present without any signs of obstruction or infection. |
|
| K80.51 | Calculus of bile duct with obstruction | Use when a CBD stone causes obstruction, evidenced by imaging and lab results. |

Primary ICD-10-CM Codes for common bile duct stone
Decision Criteria
clinical Criteria
- No evidence of ductal dilation or elevated bilirubin
Applicable To
- Choledocholithiasis without obstruction
Clinical Validation Requirements
- Imaging confirmation of CBD stone without ductal dilation
- Normal liver function tests
Code-Specific Risks
- Misclassification if obstruction is present but not documented
Coding Notes
- Ensure imaging confirms the absence of obstruction.
K80.51 - Calculus of bile duct with obstruction
Use when a CBD stone causes obstruction, evidenced by imaging and lab results.
Applicable To
- Choledocholithiasis with obstruction
Excludes
- Cholangitis (K83.0)
- Cholecystitis (K81.0-K81.9)
Clinical Validation Requirements
- Imaging showing CBD dilation >8mm
- Elevated bilirubin levels
Coding Notes
Ensure documentation of obstruction through imaging.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Common Bile Duct Stone to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K80.50.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Use specific anatomical terms, Include imaging and lab results
Impact
Reimbursement: Incorrect DRG assignment leading to potential revenue loss, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data affecting patient records
Mitigation Strategy
Ensure documentation specifies 'common bile duct' or 'CBD'.
Impact
Failure to document obstruction can lead to incorrect coding.
Mitigation Strategy
Ensure imaging and lab results are documented to support obstruction.
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.
