Mitigation Strategy
Ensure documentation includes specific category and laterality to use precise codes like H54.42A3.
Impact
High audit risk when using codes like H54.7 without specific documentation.
Mitigation Strategy
Ensure documentation specifies category and 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.
