Reimbursement: Incorrect coding can lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate health records.

Mitigation Strategy

Use the code for the underlying condition first, such as GERD or COPD.

Impact

Using R05.3 as primary when an underlying cause is identified.

Mitigation Strategy

Educate coders on proper sequencing rules.

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.
