| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A41.81 | Sepsis due to vancomycin-resistant Enterococcus | Use when sepsis is confirmed to be caused by vancomycin-resistant Enterococcus. |
|
| Z16.21 | Resistance to vancomycin | Use as a secondary code when documenting vancomycin resistance. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria
clinical Criteria
- Confirmed VRE infection with sepsis symptoms
Applicable To
- VRE sepsis
Excludes
- Sepsis due to other organisms
Clinical Validation Requirements
- Positive blood culture for Enterococcus
- Resistance to vancomycin confirmed
Code-Specific Risks
- Incorrect sequencing with resistance codes
Coding Notes
- Ensure proper sequencing: infection code first, followed by resistance code.
Z16.21 - Resistance to vancomycin
Use as a secondary code when documenting vancomycin resistance.
Applicable To
- Vancomycin-resistant Enterococcus
Excludes
- Resistance to other antibiotics
Clinical Validation Requirements
- Laboratory confirmation of vancomycin resistance
Coding Notes
Always use in conjunction with a primary infection code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Resistance to vancomycin
Z16.21Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Multidrug-Resistant Organisms to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code A41.81.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.
Mitigation Strategy
Use specific organism and resistance details, Educate staff on documentation standards
Impact
Reimbursement: Incorrect sequencing can lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Always sequence infection code before resistance code.
Impact
Incorrect sequencing of infection and resistance codes.
Mitigation Strategy
Regular training on ICD-10 guidelines.
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.
