Mitigation Strategy

Include detailed symptom descriptions, Use structured templates

Impact

Reimbursement: May lead to incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces specificity and accuracy of data.

Mitigation Strategy

Use R33.8 when BPH is the confirmed cause of retention.

Impact

Failure to sequence N40.1 before R33.8

Mitigation Strategy

Use coding guidelines to ensure proper sequencing.

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.
