Mitigation Strategy

Use 'A' for initial encounters and 'D' for subsequent encounters.

Impact

Lack of specific injury details can lead to audit findings.

Mitigation Strategy

Use detailed templates and checklists to ensure comprehensive documentation.

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.
