B95.6Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Infected Toe to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L03.031.

Impact
Reimbursement: May result in reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases the accuracy of health records.
Mitigation Strategy
Always document and code the specific side of the infection.
Impact
Failure to document laterality can lead to audit flags.
Mitigation Strategy
Implement a checklist to ensure laterality is documented in all relevant notes.
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.
