Mitigation Strategy
Review family history during intake, Use Z83.79 for relevant cases
Impact
Reimbursement: May lead to claim denials, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate patient records
Mitigation Strategy
Ensure biopsy results confirm celiac disease before coding.
Impact
Missing biopsy or serology results in records.
Mitigation Strategy
Implement checklist for required 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.
