CPT® Modifiers Mastery

The Complete Clinical Casebook: Step-by-Step Guide to Accurate Coding, Unbundling Rules, NCCI Edits, and Real-World Scenarios

Published by Precision Coding Press · Verified against current AAPC & AMA standards

Conquer the #1 Cause of Claim Denials

Over 25% of all surgical and E/M questions on the AAPC exam pivot entirely on selecting the single correct two-digit modifier. In real-world medical billing, modifier errors account for the vast majority of NCCI unbundling recoupments. CPT® Modifiers Mastery dissects 50 authentic clinical encounters across outpatient clinics, surgery centers, and endoscopy suites, providing the exact guideline citations and distractor disqualifications needed to code with total precision.
