Book synopsis

Every modifier you append to a claim is a decision that can protect your practice - or expose it to an audit. Modifier Mastery: Auditor's POV is a comprehensive, real-world guide to CPT modifier selection, written from the perspective of the auditor reviewing your claim, not just the coder submitting it.

Inside, you'll master the modifiers that matter most: E/M exceptions (24, 25, 57), surgical and procedural modifiers (50, 51, 52/53, 59 and the X-modifiers), professional/technical component splits (26/TC), teaching physician and resident billing (GC/GE), split/shared services (FS), anesthesia modifiers (P1-P6, QK/QY/AD), laboratory and pathology modifiers (90, 91, QW), and advanced applications like Modifier 22, 78, 79, 62, and 63.

Every chapter pairs clear modifier rules with correct-vs-incorrect billing scenarios drawn from real audit triggers - so you learn not just what the modifier means, but exactly how OIG and CMS reviewers evaluate your documentation. You'll also find dedicated guidance on denials and appeals, compliance program architecture, and the documentation standards that hold up under scrutiny.

Whether you're a certified coder, compliance officer, or physician who wants to understand what's really happening behind your claims, this guide gives you the audit-ready clarity to code with confidence.
