Mitigation Strategy
Ensure documentation specifies 'radial styloid' or 'de Quervain's' to use M65.4.
Impact
Lack of specific anatomical details in documentation
Mitigation Strategy
Implement detailed documentation templates
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.
