Use specific codes like G40.A09 when the diagnosis is confirmed.
Impact
Risk of audits due to incorrect seizure type coding.
Mitigation Strategy
Use detailed documentation to support code selection.
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.
