Mitigation Strategy
Use R56.9 for single seizure events without a confirmed epilepsy diagnosis.
Impact
Incorrect coding of epilepsy as a single seizure event.
Mitigation Strategy
Implement regular training on epilepsy coding guidelines.
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.
