Toxic liver disease with cholestasis
Billable Code

Decision Criteria

clinical Criteria

  • Presence of R ratio ≤2 and ALP ≥2× ULN

documentation Criteria

  • Detailed documentation of drug causality and lab findings

Applicable To

  • Drug-induced cholestatic hepatitis

Excludes

  • Alcoholic liver disease (K70.-)

Clinical Validation Requirements

  • R ratio ≤2 (ALT/ULN ÷ ALP/ULN)
  • ALP ≥2× ULN
  • Bilirubin >2.5 mg/dL

Code-Specific Risks

  • Incorrectly coding without confirming drug causality
  • Missing documentation of R ratio and lab values

Coding Notes

  • Ensure to document the specific drug and confirm cholestasis with lab values.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Cholestatic pruritus

L29.81
Use with K71.0 if pruritus is present.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Obstruction of bile duct

K83.1
Use if imaging confirms extrahepatic cholestasis.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Cholestatic Liver Injury to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K71.0.

Impact

Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.

Mitigation Strategy

Always document the specific drug causing cholestasis., Use templates to ensure completeness.

Impact

Reimbursement: May lead to denied claims due to incomplete coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of clinical data.

Mitigation Strategy

Sequence T36.0x5A → K71.0

Impact

Failure to include T-codes for drug causality.

Mitigation Strategy

Ensure all relevant T-codes are included in the coding process.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Cholestatic Liver Injury, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Cholestatic Liver Injury

Use these documentation templates to ensure complete and accurate documentation for Cholestatic Liver Injury. These templates include all required elements for proper coding and billing.

Drug-induced cholestatic hepatitis

Specialty: Hepatology

Required Elements

  • Drug name and causality
  • R ratio calculation
  • Lab values (ALP, bilirubin)
  • Imaging results

Example Documentation

46M with doxycycline-induced cholestatic hepatitis (K71.0). ALT 817 → 177 (11 days), total bilirubin 10.5 → 25.9 mg/dL. R ratio: (817/40)/(280/120) = 0.87.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Liver injury from medication
Good Documentation Example
Toxic liver injury with cholestasis secondary to doxycycline (ALT 180, ALP 300, R=1.2), confirmed by biopsy showing canalicular bile plugs.
Explanation
The good example specifies the drug, lab values, and biopsy findings, providing a complete clinical picture.
