Always link medication to the condition, Review documentation for completeness
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: May trigger audits for inappropriate coding., Data Quality: Affects accuracy of patient records.
Mitigation Strategy
Only use Z79 codes for therapies exceeding 90 days.
Impact
Risk of audits due to incorrect use of Z79 codes
Mitigation Strategy
Ensure documentation supports long-term use and links to the condition.
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.
