Impact

Reimbursement: Using unspecified codes can lead to lower reimbursement rates., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Reduces the accuracy of clinical data.

Mitigation Strategy

Impact

Failure to document laterality can lead to incorrect coding.

Mitigation Strategy

Implement mandatory fields for laterality in EHR templates.

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.
