We wrap up our Modifier 58 series with KZA Coding Expert Rebecca Mizelle exploring what payers are looking for when reviewing these claims, with content prepared by KZA Coding Expert Christine Banks. Learn why payers often evaluate Modifiers 58, 78, and 79 together, what makes staged procedures and serial debridements particularly important from an audit perspective, and how Medicare, Medicare Advantage, and commercial payer requirements can differ. Rebecca also shares practical strategies for auditing Modifier 58 claims, verifying global-period tracking and prior authorization, and building stronger appeals when correctly documented claims are denied.

In Part 3 of our Modifier 58 series, KZA Coding Expert Rebecca Mizelle breaks down common mistakes that can turn a seemingly straightforward modifier into a reimbursement or compliance problem, using content prepared by KZA Coding Expert Christine Banks. 

From incorrectly using Modifier 58 for postoperative complications to missing prospective staging documentation and failing to reset the global period, Rebecca explains where practices often go wrong. She also shares practical tips for strengthening operative-note workflows, distinguishing Modifiers 58, 78, and 79, and helping coding teams and providers get it right from the start.

In Part 2 of our Modifier 58 series, KZA Coding Expert Rebecca Mizelle takes a deeper dive into the documentation needed to support proper use of this modifier, with content prepared by KZA Coding Expert Christine Banks. Learn how documentation requirements differ depending on whether a procedure is staged or anticipated, more extensive than the original procedure, or therapy following surgery. Through real-world case studies, Rebecca illustrates why prospective documentation, clear clinical progression, and careful global-period tracking are essential to supporting Modifier 58 and keeping claims audit-ready.

In Part 1 of our Modifier 58 series, KZA Coding Expert Rebecca Mizelle walks us through the fundamentals of this staged or related procedure modifier, using content prepared by KZA Coding Expert Christine Banks. Learn the three distinct circumstances in which Modifier 58 may apply, how it differs from Modifiers 78 and 79, and what it communicates to the payer during an active global period. We also cover reimbursement, when a new global period begins, and why distinguishing a planned or expected course of care from a postoperative complication is critical for both accurate payment and compliance.

In this Modifier Mondays Spotlight episode, KZA Coding Expert Rebecca Mizelle breaks down Advance Beneficiary Notices (ABNs) and the modifiers that communicate a patient’s financial responsibility to Medicare. Rebecca reviews when an ABN should be issued, the choices available to beneficiaries, and the differences between modifiers GA, GZ, GX, and GY. She also shares important documentation and retention requirements, common mistakes practices make when completing ABNs, and why coding and billing teams should never automatically apply an ABN modifier without confirming the circumstances. Tune in for a practical refresher on using ABNs correctly, protecting your patients, and keeping your claims compliant.

We conclude our Modifier 79 series by exploring what payers are currently scrutinizing when reviewing these claims. KZA Coding Expert Christine Banks discusses Medicare, Medicare Advantage, commercial payer, and workers' compensation expectations, explains the audit triggers she's seeing most often, and shares practical strategies for appealing denials, auditing your own claims, and strengthening documentation. Learn how proactive workflows can help protect reimbursement while maintaining compliance.

In Part 3 of our Modifier 79 series, Christine Banks explores the most common coding mistakes she encounters during audits, from billing postoperative pain management incorrectly to confusing Modifiers 79, 78, and 24. She also shares practical workflow tips to help practices identify unrelated procedures, properly track overlapping global periods, educate providers, and avoid costly denials and compliance issues.

Part 2 of our Modifier 79 series takes a deeper dive into the documentation required to support unrelated procedures performed during an active global period. KZA Coding Expert Christine Banks shares practical documentation tips, explains how to distinguish truly unrelated conditions, and walks through real-world orthopedic and general surgery case studies that demonstrate proper application of Modifier 79. You'll also learn why tracking overlapping global periods is essential for coding and scheduling teams alike.

In Part 1 of our Modifier 79 series, KZA Coding Expert Christine Banks breaks down the definition and proper use of this often-confused modifier. Learn when Modifier 79 should be used for unrelated procedures performed during a postoperative global period, how it differs from Modifiers 58 and 78, and why understanding these distinctions is critical for accurate reimbursement. Christine also explains how Modifier 79 impacts global periods and highlights common mistakes that can lead to denials or lost revenue.

We wrap up our Modifier 78 series with KZA Coding Expert Christine Banks, who shares what she's seeing in today's payer landscape surrounding unplanned returns to the operating room. From increased audit activity and denial trends to differences between Medicare, Medicare Advantage, commercial payers, and workers' compensation, Christine explains how payer expectations are evolving and what practices can do to stay ahead. Learn practical strategies for appealing denials, educating surgeons, reviewing payer contracts, and identifying missed reimbursement opportunities—all while reducing compliance risk.
