Reporting modifier 78 for a staged procedure? Expect denials.

When it comes to appending CPT® modifiers to your codes, the rules can be daunting, and Medicare’s regulations only compound the confusion. But if you’re up to speed on these key modifier billing practices, you’ll be raking in deserved pay.

If the physician who renders the interpretation is with a separate professional group and is not a hospital employee, you should report the service with modifier 26 to obtain his proper share of the reimbursement.

Key: You’ll report modifier 78 (Unplanned return to the operating room for a related procedure during the postoperative period) when conditions arising from the initial surgery (complications) rather than the patient’s condition...
