Mitigation Strategy
Query provider to confirm TGA criteria are met.
Impact
Inadequate documentation may lead to audit findings.
Mitigation Strategy
Use detailed templates and confirm all TGA criteria are documented.
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.
