Overview

Updated annually, Green's best-selling 3-2-1 CODE IT! 2025 Edition, and MindTap digital learning solutions, equip beginning coders with a comprehensive introduction to today's medical coding. Revised annually to provide the most current information, this easy-to-use medical coding resource addresses the latest changes to the ICD-10-CM, ICD-10-PCS, CPT® and HCPCS Level II code sets. Students begin with diagnosis coding and progress to coding procedures and services. Separate chapters review inpatient and outpatient coding and differentiate general and specific ICD-10-CM, ICD-10-PCS, HCPCS Level II and CPT coding and guidelines. Examples, defined terms and printed and digital practice opportunities reinforce concepts. Computer-assisted coding cases and professional encoder software help prepare students for entry-level coding positions and professional coding credentials.
