Use modifier 59 only when procedures are distinct and separate.
Impact
Failure to document comorbidities can lead to audit issues.
Mitigation Strategy
Use checklists to ensure all comorbidities 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.
