Mitigation Strategy
Use templates that prompt for laterality., Educate providers on documentation standards.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces the accuracy of clinical data.
Mitigation Strategy
Always document and code the specific side affected.
Impact
Failure to document laterality can lead to audit findings.
Mitigation Strategy
Implement mandatory fields in EHR for laterality.
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.
