Which type of procedure is most likely to be affected by RAC audits?

High-cost procedures with significant revenue impact are most likely to be affected by Recovery Audit Contractor (RAC) audits due to the financial implications associated with these services. RAC audits primarily aim to identify improper payments made by Medicare, and these audits focus on procedures that can lead to substantial financial losses for the program if billed incorrectly.

When high-cost procedures are involved, any discrepancies in coding or billing practices can result in significant revenue adjustments, making them prime targets for audit scrutiny. The financial stakes associated with these procedures mean that auditors will closely review them to ensure compliance with billing regulations and accurate documentation.

While other types of procedures mentioned may also undergo audits, those with substantial revenue implications are more likely to trigger focused scrutiny due to their potential impact on Medicare costs. This heightened review process reinforces the need for providers to ensure their documentation and coding practices are accurate and in compliance with regulations, especially for procedures that can significantly affect overall reimbursement.
